delivered the opinion of the Court.
This was an action of assumpsit, instituted by the appellee against the appellant, to recover the sum of $2,000, the balance of salary for the year 1869. The ground of the action *59is, that the appellant, through its agent, had contracted with the appellee to employ him for the entire year of 1869, at a salary of $4,000, payable monthly, and that he was wrongfully dismissed from the service of the appellant on the first of July, 1869, up to which date his salary was paid.
At the trial in the Court below several bills of exceptions were taken by the appellant; but as the fourth and fifth exceptions involve questions of a preliminary character, we shall dispose of them before considering the questions raised by the other exceptions, which are of a different nature.
And as to the fourth exception, we discover nothing in it to justify a reversal of the judgment appealed from. Whether a continuance should have been ordered, after the amendment of the appellee’s declaration, was matter of discretion, which is exclusively confided to the Court in which the amendment takes place; and no appeal lies from its exercise. Code, Art. 75, secs. 23 and 24. If the Court below was not satisfied that the ends of justice required a continuance, it was clearly right in refusing to grant it; and no mere rule of Court could be allowed to operate to divest such discretion, or in any manner to change or modify the statutory provision on the subject. Rules of Court must not be in conflict or inconsistent with the Statute law of the State.
The fifth exception was taken to the' refusal of the Court to order the removal of the cause into the Circuit Court of the United States for the district of Maryland; and, under the facts disclosed by the record, wo think the Court was entirely right in such refusal.
The cause was in progress of trial, and three bills of exceptions had been taken to the rulings as to the admissibility of evidence, when the application for removal was made; and according to what we regard as the true and plain interpretation of the Act of Congress, under which the right of removal is claimed, being that approved March 2d, 1867, entitled “An Act to amend an Act entitled ‘An Act for the removal of causes in certain cases from State Courts,’ approved July 27, *601866,” the application came too late to stay the further progress of the trial. By this amendatory Act of 1867, it is provided, “That where a suit is now pending, or may hereafter be brought in any State Court, in which there is a controversy between a citizen of the State in which the suit is brought and a citizen of another State, and the matter in dispute exceeds the sum of $500, exclusive of costs, such citizen of another State, whether he be plaintiff or defendant, if he will make and file, in such State Court, an affidavit stating that he has reason to and does believe that, from prejudice or local influence, he will not be able to obtain justice in such State Court, may, at any time before the final hearing or trial of the suit, file a petition in such State Court for the removal of the suit into the next Circuit Court of the United States to be held in the district where the suit is pending, and offer good and sufficient surety for his entering in such Court, on the first day of its session, copies of all process, pleadings, depositions, testimony, and other proceedings in such suit, and doing such other appropriate acts as, by the Act to which this Act is amendatory, are required to be done, upon the removal of a suit into the United States Courts.” 14 Statutes at Large, 306, 558. This Act, so far as it is applicable to defendants, is but a modification of the 12th section of the Judiciary Act of 1789,. and while by the Act of 1789 the application for removal was required to be made at the time of the defendant’s appearance entered in the cause, by the words of the latter Act of 1867, the right to apply for removal is extended to any time before final hearing or trial ; and as, in this case, the trial ha.d actually commenced, and several questions in its progress had been decided before the application was filed, such application cannot be said to have been made before trial. The application should have been made before the hearing or trial commenced; for otherwise it would be impossible to determine at what stage of the trial the application would be proper. Could it be made at the last stage of the trial, after all the legal questions had been *61decided by the Court, and the facts submitted to the jury, but before the verdict found? We can hardly suppose that any one would seriously attempt to maintain such a proposition. And if not in such case, at Avhat prior stage of the trial Avould the application be admissible ? W e think it clear, that it is not at any time before the conclusion, but at any time before the commencement of the trial, that the application to remove must be made.
It AA'as contended, however, that because the appellee Avas alloAved to amend his declaration after the commencement of the trial, by inserting a special count therein, there Avas a neAV issue made, and that, as to that part of the case, the trial did not in fact commence until after pleas filed to the amended declaration, and issues joined thereon; and as the application to remove AA’as made before the amended declaration Avas pleaded to, it should be regarded as made in due time. But in this view of the subject avo do not concur. The pending trial did not terminate by the leave to amend; for as the substance of the issue Avas not materially changed by the amendment, the jury Avas not required to be re-sworn; but all the evidence previously given remained before them, as if no amendment had been make. Garrett vs. Dickerson, 19 Md., 418. Amendments that are proper to secure the trial of the real merits of the cause may be made at any time before the jury retire to make up their verdict; and unless the issue is materially changed by the amendment, or a continuance is deemed necessary to the ends of justice, Avhere the amendment is made during the course of the trial, a juror is never Avithdraivn, as AA’as the practice prior to the Act of 1852; but the cause proceeds as if no amendment had been made. Code, Art. 75, secs. 23, 24. The making of the amendment, therefore, afforded no ground for alloAving the application for removal.
But the failure to make the application in due time Avas not the only objection to the right of removal in this case. The appellant is alleged to be a corporation chartered by the *62State of New York, where it has its principal office, and therefore claims to be regarded as a citizen of that State, and thus within the provisions of the Act of Congress referred to, which was passed to regulate the exercise of jurisdiction of the Federal Courts over controversies between citizens of different States, conferred by section 2, Article 3, of the Constitution of the United States. And, according to the decisions of the Supreme Court of the United States, the appellant is certainly entitled to be so regarded and treated, in reference to the question of Federal jurisdiction; for it is now settled, by a series of decisions of that high tribunal, that where a corporation is created by the laws of a State, the legal presumption is, that its members are citizens of the State in which alone the corporate body has a legal existence; and any suit by or against such corporation, in its corporate name, must be presumed to be a suit by or against' citizens of the State creating the body corporate; and that no averment or evidence to the contrary is admissible for the purpose of withdrawing the suit from the jurisdiction of the Courts of the United States. Louisville, Cin. & Charleston Railroad Co. vs. Letson, 2 How., 497; Marshall vs. The Balt. & Ohio Railroad Co., 16 How., 325; Covington Drawbridge Co. vs. Shepherd, 20 How., 231; Ohio & Miss. Railroad Co. vs. Wheeler, 1 Bl., 286. But while this is the ease in reference to the defendant, it no where appears in the record that the plaintiff is a citizen of Maryland; and according to the recent case of The Insurance Co. vs. Francis, 11 Wall., 210, in order to entitle a party to the right of removal under the Act of Congress, it must affirmatively appear, either by the pleadings in the cause, or other appropriate allegation, that the party desiring the removal is a citizen of another State than that in which the suit is pending, and that the adverse party is a citizen of the particular State in whose Court the suit was brought. So that, in any aspect of the case as the record presents it, it would have been erroneous for the Court to have granted the prayer for removal.
*63Having disposed of the questions raised by the fourth and fifth bills of exceptions, we shall now proceed to consider the other questions in the case, and which relate to the admissibility of evidence, and the propriety of granting and refusing certain instructions to the jury. And before referring particularly to each several exception remaining to be considered, we shall state the leading and undisputed facts of the ease, and the general principles of law that would seem to be applicable to them.
The appellee was employed, according to his own testimony, by the appellant, from 1852 to the time of his discharge in July, 1869, as assistant superintendent, and the contract of employment was made with Samuel M. Shoemaker, as the appellant’s agent and general superintendent for this district. His employment was yearly, from January to January; and in 1867 his .salary was $4,000, and continued at that amount to the close of his service. He was notified of his discharge on the 28th of June, 1869, to take effect from the 30th of that month, and no reason for the discharge was given at the time. He further proved, by his own evidence, that from November, 1868, up to the time of his dismissal, he had been interested, with certain other parties, as the Philadelphia, "Wilmington and Baltimore Transfer Company, in conveying freight from the President street railroad station to consignees in Baltimore; and that the business of the appellant was and is to transport freight from city to city, and that, with exception of freight transported by its own company, it did not deliver freight to consignees in Baltimore. He also proved, on cross-examination, that in April or May, 1869, he was notified by Shoemaker, the general superintendent, that the appellant disapproved of his connection with the Baltimore Transfer Company, and that it demanded that he should cease his connection with that concern; that he tried to sell out his interest, but did not; that lie waited, in his own language, “for something to turn up.” Ho also proved, that at the time of his dismissal he had overdrawn *64the salary due to that date, some $500, which he afterwards paid back. That he had authority over the subordinate officers of the appellant. These facts were all proven by the appellee himself, and therefore, so far as he is concerned, and as against him, may be taken as true.
It was also proved, that the authority of Shoemaker, as general superintendent of the Maryland district, was to supervise the working and general management of the business and affairs of the company in such district, and to appoint and discharge agents and other subordinate employés. It was proved, moreover, that Shoemaker was well aware of the appellee’s connection with the Transfer Company, from the time such connection commenced.
There was also proof tending to show, that in fact the operations of the Transfer Company, of which the appellee was a member, did injuriously conflict and compete Avith the operations and interest of the appellant, in Baltimore.
On this state of case, the main question is, whether there was justification for the dismissal of the appellee; and this involves the further question as to the extent of the authority of Shoemaker, the general superintendent, by whom the appellee was employed and retained in service, with knowledge of the fact that the latter was connected with the Baltimore Transfer Co.; the other questions raised, and to be decided, being subordinate to these.
Whether there existed, as matter of fact, sufficient ground for the discharge of the appellee, Avas, of course, a question for the jury; but, as a principle of law, it may be stated generally, that the appellee, by the nature of his employment, Avas impliedly bound to serve the appellant faithfully, and to refrain from doing any act knowingly and wilfully Avhich might affect injuriously the business of his employer. It has been expressly decided, that a servant, Avhile engaged in the service of his master, has no right to do any act which may injure his trade, or undermine his business. Nichol vs. Martyn, 2 Esp. Rep., 732. And in the case of Lacy vs. Osbaldiston, 8 *65C. & P., 80, brought for wrongfully discharging the plaintiff as an acting manager of a theatre, it was held, that if the plaintiff had so conducted himself as to render it injurious to the interest of the theatre to retain him, the proprietor might lawfully dismiss him; the learned Judge, in summing up, saying to the jury, that, as to the dismissal, it was a question of fact whether the plaintiff was so conducting himself as that it would have been injurious to the interests of the theatre to have kept him; and if so, he should have no difficulty in saying that it would be a good ground of dismissal. And the same principle is distinctly recognized by this Court, in the case of Jaffray vs. King, 34 Md., 220.
But it is insisted by the appellee that, as he became interested in the Baltimore Transfer Company in the fall of 1868 j with the knowledge and consent of Shoemaker, the general superintendent of the appellant, and was afterwards retained in service as he had been before, by such superintendent, it became a condition in the contract of employment that he should be allowed to hold such connection with the Transfer Company, and that the appellant is, in effect, estopped from setting up any such cause of dismissal as is relied on by it. And this, of necessity, involves the question of the extent of Shoemaker’s authority, and the effect of his knowledge of and acquiescence in the appellee’s connection with the Transfer Company.
Now, assuming that the authority of Shoemaker was as broad and comprehensive as contended by the appellee, that is, that he was authorized to employ and discharge employés and agents, and direct their conduct, make contracts, and exercise generally supervision over the business of the appellant, in the particular division; still, wc think it would be difficult to maintain that such delegation of authority included power in the agent to license or authorize one of the coemployes, who was himself entrusted with large and important control over the business transactions of the appellant, to engage in and carry on a business in competition with that which he *66had been employed to foster and promote. To bind the appellant as principal it is incumbent on the'appellee to show that the agent, with whom he dealt, had competent authority. The authority shown is simply that by which the agent was empowered to enter into all such contracts as were usually and properly entered into in the ordinary conduct and management of the business. To this extent and no further can the authority here shown be carried by any fair construction of it; nor would it be rational to presume that it was the intention of the principal to clothe the agent with authority to contract in a manner to inflict serious injury on its business. Was then the license or authority given to the appellee by the general superintendent, to maintain the connection with the Transfer Company, if it did in fact compete with and was injurious to the business of the appellant, such an act as was.done in the usual and ordinary conduct and management of its affairs? To maintain such a proposition it would require affirmative proof on the part of the appellee; for it certainly does not result by any reasonable construction of the power shown. If powers like the present were construed as contended for by the appellee, there would be no safety for principals. Instead of having their business supervised in their own interests, by agents bound to them by obligations of fidelity and good faith, they might be compelled to retain in their service, at large salaries, agents engaged at the time in undermining and destroying their trade; a state of things that no principal should be presumed to have authorized. The rule of construction in such cases, is well settled. If the authority is special, says Judge Story, (Sto. on Ag., seo. 83,) “it is construed.to include only the usual means appropriate to the end. If the authority is general, it is still construed to be limited to the usual means to accomplish the end. Even if a general discretion is vested in the agent, it is not deemed to be unlimited. But it must be exercised in a reasonable manner, and cannot be resorted to in order to justify acts, which the principal could not be *67presumed to intend; or which would defeat, and not promote, the apparent end or purpose, for which the power was given.”
This rule, for the construction of powers like the present, is well stated, with many illustrations of its application from decided cases, by the editors in 1 Amer. Lead. Cases, 567. It is there said, that “ it is a universal principle in the law of agency, that the powers of the agent are to be exercised for the benefit of the principal only, and not of the agent or of third parties. A power to do all acts that the principal could do, or all acts of a certain description, for and in the name of the principal, is limited to the doing of them for the use and benefit of the principal only, as much as if it were so expressed. Stainer vs. Tysen, 3 Hill, (N. Y.,) 279, 281; North River Bank vs. Aymar, 3 Hill, (N. Y.,) 263, 266. A power, therefore, in the most general terms, to draw and indorse bills for and in the name of the principal, will not authorize a drawing or indorsing in his name for the accommodation of third persons. Nichols vs. State Bank, 3 Yerger, 107; Wallace vs. Branch Bank at Mobile, 1 Judges’, Ala., 565; St. John vs. Redmond, 9 Porter, 428; The Planter's’ Bank vs. Cameron, 3 Sm. & Mars., 609, 613; or for the benefit of the agent. Suckley vs. Tunno & Cox, 1 Brevard, 257; S. C., 2 Bay, 505; and this principle is illustrated in the case of partnership. A power in the most general terms to do all and everything that the agent may think proper in any business the principal may be concerned or interested in, will not authorize the agent to pledge the property of the principal for his own debt. Hewes vs. Dodridge, 1 Robinson’s Va. Rep., 143. The most guiding principle in the construction of powers, is to be derived from a consideration of the purpose which the agent, or other depositary of power, is appointed to accomplish.”
Seeing then that the power of the agent is delegated exclusively for the benefit of the principal, and is to be exercised alone for the promotion of what is supposed to be his interest, there is clearly no ground for contending that the agent could *68bind the principal by any such license or authority as that given the appellee in this case, if it be found that such license or authority was or could be used to the prejudice and injury of the appellant; and, if such be the fact, the appellee himself must be taken to have been cognizant of it, and therefore bound to refrain from forming the connection with the Transfer Company.
It is insisted, however, that because the general superintendent of the appellant had notice, at the time of the retention of the appellee in service for the year 1869, of the latter’s interest in the Transfer Company, that, notwithstanding the agent may have had no authority to authorize such a connection on the part of the appellee, such notice is in law notice to the principal, and as the appellee was retained in service with such notice, the employment became subject to the appellee’s right to retain his interest in the Transfer Company. But to this proposition we do not assent. It is true, notice to an agent of facts arising from and growing out of the subject-matter of his agency, is constructive notice to the principal. But this rule has no application to the case where the question is, whether the act relied on to bind the principal, was done within the limits and scope of the agent’s authority or not. If knowledge of the agent could fix liability upon the principal in such case, irrespective of the limit of the former’s authority, the cases of Grant vs. Norway, 10 C. B., 665; Hubbersty vs. Ward, 8 Exch., 830; Coleman vs. Riches, 29 Eng. L. & Eq. Rep., 323, and many other cases to which reference could be made, would have resulted in very different judgments from what they did. In the first two cases named, it was held, that, though a master of a vessel has a general authority to execute bills of lading for goods shipped, he has no power to charge the owner by signing bills of lading for a greater quantity of goods than those on board, and that a bill of lading so signed would not bind the owner, even in the hands of innocent third parties. And in the last named case, where the agent of a wharfinger, whose duty it was to *69give receipts for goods actually received, gave a receipt for goods which had not been received, the principal was held not to be responsible, even to third parties who had been deceived by the receipt, because it was not within the scope of the agent’s authority in the course of his employment, to give such a receipt. In this case the appellee was himself an agent of the appellant, and he must be supposed to have known something of the extent of the authority of the superior agent, upon whose knowledge and acquiescence he relies.
It is true, the act of the agent, though unauthorized at the time, may become binding upon the principal, by ratification and adoption. But to make such ratification effectual it must be shown that there was previous knowledge on the part of the principal of all the material facts and circumstances attending the act to be ratified. Bell vs. Cunningham, 3 Pet., 81; Owens vs. Hull, 9 Pet., 607; The Pennsylvania, Delaware and Maryland Steam Nav. Co. vs. Dandridge, 8 Gill & John., 249; Mayor & C. C. of Balto. vs. Reynolds, 20 Md., 1. If the principal assents to the act while ignorant of the facts attending it, he may disaffirm it when informed of such facts. 6 Pick., 198. And it is equally true, that where an act is done in behalf of the principal, though not within the authority of the agent, if the former has full knowledge upon the subject, and from which act he derives benefit, he must dissent and give notice of the fact within a reasonable time, or his assent and ratification will be presumed. Brigham vs. Peter, 1 Gray, 147. So that, in this case, if the services of the appellee were accepted by the appellant, with full knowledge of the former’s connection with the Transfer Company, sanctioned and authorized by its agent, at the time of the last yearly employment, and of the manner in which the operations of that company might affect the business of the appellant in Baltimore, the latter was bound to signify its dissent within a reasonable time from the time it became possessed of the knowledge; or otherwise be concluded by a presumed assent and ratification. But then, it would be incumbent *70upon the appellee to show notice in fact on the part of the appellant, and at what time it was received.
With these principles in view, there can be but little difficulty in disposing of the remaining exceptions.
The first, exception was taken to the admissibility in evidence of the declaration of the appellee himself, made to Shoemaker, the superintendent, after notice of the fact of dismissal, to the effect, that he intended to hold the appellant responsible for his year’s salary. Upon what principle this declaration was admitted in evidence, we are at a loss to understand. It was in fact wholly immaterial. It served to prove nothing that was essential to the case. If the appellee had been wrongfully dismissed, as he alleges, it required no such notice or declaration to entitle him to maintain his action; and as the order for the dismissal came from the appellant, it is manifest that Shoemaker had no power or authority to revoke it, or in any manner to act upon the notification of .the appellee, so as to bind his principal. The mere declaration of the party himself, made to another not authorized to receive or act upon it, is clearly not admissible; and the Court was therefore in error in allowing such a declaration to go to the jury. 29 Md., 194.
The second, aud third exceptions present in effect but one and the same question; and that is, whether Shoemaker’s knowledge and sanction of the appellee’s connection with the Transfer Company before the commencement of the year’s service of 1869, so affected the appellant as to preclude the right to dismiss the ap'pellee because of such connection.
We have already said that the power shown to have been delegated to Shoemaker, as superintendent, did not authorize him to sanction and license the appellee’s connection with that company, if in point of fact it was a competing concern with the appellant. The proof stated in these bills of exceptions, it is true, tended to show that, at the time, it was the opinion of the agent that the connection of the appellee with the Transfer Company would not be injurious to the interests of *71the appellant; but we know of no rule by which the principal is bound by the mere opinion of his agent, unless authorized to give it to influence the action of third parties.
This evidence might have been made admissible, if the appellee had proposed to follow it up with other evidence to prove that such knowledge of the agent had been communicated to the principal, and that the latter had ratified the sanction given by the agent, either expressly or by presumption. But no such offer was made, and it was therefore error to allow the evidence to be given to the jury.
We come now to the prayers that were offered, some of which were granted and others refused, contained in the appellant’s sixth exception.
The first prayer on the part of the appellee, and which was granted, we think correct, and properly instructed the jury as to the law of the ease. We do not understand that this instruction was seriously questioned. But the second prayer of the appellee, which was also granted, we regard as essentially erroneous, and should have been refused. It asserts, after stating the extent and limit of the authority supposed to have been delegated to Shoemaker, and the employment by him of the appellee, that the jury were at liberty to find “that in regard to all matters and things pertaining to or affecting said contract of employment, the knowledge and consent of the said superintendent or general agent, was the knowledge and consent of the defendant.” This, if it means what we suppose it does, or was intended to mean, is a proposition that cannot be sustained. We have already said that the knowledge of the agent in regard to matters with which he was connected beyond the scope of his authority is not the knowledge of his principal, and that the doctrine by which notice to the agent is to be regarded as notice to his principal does not apply to a case like the present. If the agent transcended his authority in giving sanction to or allowing conduct on the part of the appellee that afforded just ground of complaint by the principal, the latter had the undoubted *72right to repudiate the act of its agent. And though it may be said in this case, that the license or sanction given by the superintendent to the appellee to form the connection with the Transfer Company, in some sense inhered in the contract of employment, still, it is an established principle, that if an agent does an act within the scope of his authority, and at the same time does something more which he was not authorized to do, and the two matters are not inseparable, even though both may relate to the same subject, that which was authorized is alone binding, and the other void, so far as the principal is concerned. 2 Greenl. Ev., see. 59. Here the matters are not only separable, but are quite distinct, the sanction given to hold the relation to the Transfer Company being collateral to the employment of the appellee.
The second prayer of the appellant would be free from objection, if it had been more explicit in submitting to the jury the question whether the appellee’s connection with the Transfer Company, was in violation of his duties to the appellant, and injurious to its interest. Objection was taken to the prayer in the Court below on the ground that it assumed that such connection of the appellee was in violation of his duty, and that the interest of the appellant was affected thereby. If such be the proper reading of the prayer it would certainly render it objectionable; and, upon a careful examination, we think it is susceptible of the construction placed upon it by the appellee, whatever may have been the intention of its author; and it was therefore properly rejected. The prayer should have been explicit and free from all ambiguity in submitting that question to the jury, as it was one most material in the case.
The fourth prayer of the appellant, however, is free from the objection taken to the second, and should have.been granted. It fairly submitted to the finding of the jury all the facts upon which the right of dismissal depended; and as these two prayers, the second and fourth, embrace the more general proposition announced in the third prayer of *73the appellant, this latter prayer may be regarded as immaterial, and hence it becomes unnecessary to say more in reference to it.
(Decided 12th January, 1872.)For the errors stated, we shall reverse the judgment of the Court below, and award a new trial.
