The plaintiff’s declaration contains two counts.
The first count alleges a breach of a written contract, and the second is a count upon an account annexed. There is no question between the parties as to the second count.
The written instrument annexed to the plaintiff’s declaration constitutes a valid, legal contract, binding upon the parties. The defendant, being the owner of a certain parcel of land in Salem upon which there was a trap rock ledge which she desired to have removed to a certain level, entered into a contract with the plaintiff, by the terms whereof she agreed “to permit the said McDonough to go upon the said premises, put in derricks, crushers and other stone machinery, suitable to remove the said stone and in such form and at such times as the said Almy may direct.” The Contract also provides that the defendant is to “sell such stone and in such form as it may be needed and directed by her, and she agrees to pay to the said McDonough the sum of sixty-five cents per ton for crushed stone suitable for the market as ordered by her. And for all cellar stone that may be produced in blasting, she agrees to pay the said McDonough, when she directs the delivery thereof, at the rate of three cents a face foot in an eighteen inch wall. All other building stone she agrees to pay the said McDonough at the same rate last mentioned and under the same style of measurement.” There are certain other provisions of the contract not material to the issues between the parties. This *415contract appears to be clear and explicit in its terms and free from ambiguity. It does not in terms contain any agreement on the part of the defendant that she will furnish to the plaintiff or obtain for him any permit or license to enable him to operate a steam engine or boiler in the performance of his work, nor can any such undertaking on her part be reasonably inferred from the language employed. When the contract was entered into there was an ordinance in force in the city of Salem which provided that "No . . . stationary steam boiler from which power is to be taken or any other fuel than coal or coke is to be used to create steam and no stationary steam engine shall be hereafter erected or put up to be used in this city without a license obtained from the board of aldermen; provided however that no such license shall be required for such an engine unless the same is to be erected within five hundred feet of a dwelling house or a public building.” The undisputed evidence shows that the plaintiff erected a boiler and engine upon the defendant’s land within a distance of five hundred feet from dwelling houses, and without a license or permit therefor, and that thereafter he was prohibited by the city officials from operating it. The plaintiff contends that no license was required of him for the erection of such steam engine and boiler.
Having entered into the contract the plaintiff was bound to carry out the part of it which he had agreed to perform unless he was prevented or excused therefrom by the conduct of the defendant. He could not, however, violate the law or ordinances of the city of Salem in an attempt to perform the work undertaken, but was bound to its performance in a lawful manner. The contract is absolute in its terms and contains no condition that the plaintiff’s obligations thereunder shall be dependent upon his being able to secure proper license to enable bim to perform the work which he agrees to do. When the contract between the parties was entered into, the defendant held a license from the board of aldermen to erect and maintain an engine and boiler on Cliff Street, where the plaintiff could have carried on the work, even if not so advantageously as it could have been carried on had the plaintiff’s plant been on the Y Street side; and no contention is made that the plaintiff could not have acted under the license so granted. The contract therefore could have been per*416formed by the plaintiff in such a manner as to violate no law, and he is bound by its terms. Gaston v. Gordon, 208 Mass. 265. If the plaintiff believed that he could erect and operate his engine and boiler without a license, even if such a license was required, or that no license was required under the ordinance, he could not be legally excused from the performance of his contract if he found that he was mistaken as to his rights, but was required to proceed to do the work at such a place on the lot as he might lawfully occupy for that purpose.
The plaintiff contends that the engine erected by him was not stationary but portable, and that therefore the ordinance did not apply. This contention brings us to the plaintiff’s first exception, which is to the instruction of the presiding judge that the steam engine erected by the plaintiff was a “stationary steam engine” within the meaning of the ordinance. We are of opinion that this ruling was right. There is no controversy between the parties as to the manner in which the engine was installed or the length of time it would remain upon the defendant’s land in the performance of the work. The evidence shows that it was set upon a concrete foundation and bolted and braced to the concrete in such a manner as to be stationary and immovable, and free from vibration. There was also evidence to show that it would be used in the same location for a period of at least two or three years. Whatever may have been the character of the engine when it was brought to the plaintiff’s land, we have no doubt that when it was set upon the concrete foundation and permanently attached thereto for the purpose of being used two or three years, it became a “stationary steam engine” within the meaning of the ordinance. The word “stationary” is defined as “fixed in a certain station,” “a steam engine permanently placed;” while “portable” accurately describes an object “capable of being borne or carried; easily transported.” Webster’s New International Dictionary. Accordingly the ruling that the engine was a “stationary steam engine,” as that term was used in the ordinance, was correct, and the exception must be overruled.
After the contract was made, the plaintiff erected a steam engine and boiler, built bins and started to set up his stone crusher on the Y Street side of the lot. There was evidence to show that *417before the plaintiff began work crushing stone he was informed that he could not run his stone crusher where it had been located; that he stated to the defendant that he had made a mistake in starting to work on the wrong side of the ledge, and that he asked her if she would try to get a permit or license so that he could work on the Y Street side; that in compliance with this request the defendant made application to the board of aldermen for a license to erect a steam engine and boiler upon different portions of the lot, and that after hearing this application was denied. The defendant testified that she told the plaintiff, before he had installed bis engine and boiler on the Y Street side of the ledge, that she had no license to erect a steam engine and boiler there but did have a license to erect such engine and boiler on the Cliff Street side; that later he told her he was going to place his crusher on the Y Street side of the lot, and that she replied that if he put his crusher on that side of the ledge he did it upon his own responsibility, and that he must take all the responsibility and risk of loss; and that the plaintiff replied “I will.” The plaintiff contended that stone could be taken from the ledge and crushed on the Y Street side at less expense than from the upper, or Cliff Street, side of the ledge. The defendant testified that after her application for a license had been denied by the board of aldermen, the plaintiff stated to her that he would not move his stone crusher and other machinery to Cliff Street because of the expense involved in such removal. The plaintiff testified that the defendant notified him, after the application for a license had been denied, that he must stop work, and that she thereby terminated the contract to his damage. This is the breach of the contract specified by the plaintiff. The defendant denied that she ever stopped the plaintiff from carrying out his contract, or interfered with its performance, aside from stating to him that if he undertook to operate his steam engine and stone crusher on the Y Street side of the lot he must take all the responsibility and risk of loss.
The judge correctly instructed the jury that if the defendant refused to permit the plaintiff to perform his contract and ordered him to stop work, that would amount to a breach of the contract on her part, and their verdict should be for the plaintiff on the first count. As the verdict was for the defendant on that count *418the plaintiff must have failed to satisfy the jury that he was forbidden or prevented by the defendant from carrying out his contract. The case was referred to an auditor, who also found that the defendant did not unqualifiedly forbid the plaintiff to carry on his work.
The plaintiff excepted to the refusal of the judge to give twenty requests for instructions. The requests numbered 2, 3 and 4 could not have been given, as it was no part of the duty of the defendant to procure a license to enable the plaintiff to perform his work. The fifth request also could not have been given, because there is no evidence to warrant a finding that the defendant required the plaintiff to begin his operations at any particular place on the premises. The seventh request was rightly refused. If the defendant, at the plaintiff’s request, saw fit to apply for a license so that the plaintiff could operate his stone crusher on the Y Street side of the ledge, it would not be an admission by her of the right of the plaintiff to operate his plant there or elsewhere. The eighth request was rightly denied, because the contract is not ambiguous in its terms. The ninth request assumes that the defendant notified the plaintiff that he would have to stop work. This was denied by the defendant and was the principal issue of fact between the parties to be determined by the jury under the first count and so could not have been given. The tenth and eleventh requests were rightly refused. The defendant was not bound, for the reasons previously stated, to secure permits to enable the plaintiff to perform his contract. The twelfth and thirteenth requests could not have been given because, if a license was refused to operate the plant on the Y Street side of the premises, the plaintiff might have operated it on Cliff Street or on any other part of the premises where a license could be obtained for that purpose, if such license was required. The fourteenth, fifteenth, sixteenth, seventeenth and eighteenth requests assumed that the defendant was bound to procure the necessary licenses to enable the plaintiff to perform his contract, but as no such obligation rested upon the defendant, these requests could not have been given. The twentieth request was rightly denied. As no appreciable amount of stone ever was quarried, there was no occasion to obtain orders to sell it; besides, this request relates to damages and, in view of the verdict of the jury, has become *419immaterial. The twenty-first request was denied rightly. Whether the defendant failed to perform her part of the contract was a question for the jury upon conflicting evidence. The judge having correctly ruled as matter of law that the steam engine and boiler erected by the defendant were stationary, the twenty-second request was rightly refused.
The presiding judge gave four instructions to the jury at the request of the defendant, and the plaintiff excepted. The defendant’s request numbered 16 was immaterial because there was no evidence to show that any cellar stone was procured or quarried by the plaintiff. The plaintiff thérefore could not have been harmed by the instruction given. The defendant’s requests numbered 25 and 26 would seem not to have been material to any issue in the case, and we do not think that the plaintiff was prejudiced thereby. If a license to blast was required in order that the plaintiff might legally perform his contract, it was his duty to obtain it for the same reason that it was his duty to obtain a license to erect a stationary steam boiler and engine. The exception to the giving of the defendant’s request numbered 32 cannot be sustained. If the plaintiff could not obtain a license to operate on Y Street, he was not thereby excused from the performance of the contract, but was bound to carry on his work on such portion of the premises as he could occupy for that purpose.
It is plain that none of the plaintiff’s exceptions can be sustained. The case seems to have been carefully tried by the judge of the Superior Court; his instructions were full, clear and accurate, and were well calculated to assist the jury in arriving at a correct conclusion.
Exceptions overruled.
