1. A question of practice as to trials at law before a judge sitting without a jury lies at the threshold. The defendant seasonably presented requests for rulings. It is said in the exceptions that “ these requests though not expressly passed on by the court are to be treated as refused, the defendant having duly reserved its exceptions, it being understood, however, that the facts assumed or hypothetically stated in these requests are to be taken as true only in so far as sustained by the evidence herein contained and referred to.” We interpret this as meaning that the requests were refused. If the court ignored them the defendant’s rights can be no higher than if the court refused them. It means further that if on any view of the evidence reported, the facts assumed in the requests can be found, then the facts are to be treated as so found. We are led to this construction of the exceptions because it is the only one which is fair to the excepting party. Otherwise it could not be determined what the view of the Superior Court was as to the matters covered by the prayers. The Superior Court judge filed no memorandum and made only a general finding for the plaintiff. One branch of the plaintiff’s argument has been that the exceptions must be overruled on the ground that it must be assumed that the judge did not find the facts recited in the prayers and that so far as bald requests for correct rulings of law have been refused it must be assumed that facts have been found by the judge which made inapplicable such principles. While a case may be imagined where such an argument may prevail, it cannot ordinarily, nor in this case. When controverted issues of fact are tried without a jury, before a judge who makes only a general finding, it would be manifestly unjust if the defeated party could not be assured in some way that correct rules of law have been followed. Where the facts are not agreed and no memorandum of findings is filed, commonly it cannot be certain precisely what facts are found or which witnesses are believed by the trial judge in reaching his conclusions. If it *18were necessary for an excepting- party not only to maintain the soundness of the law as stated in his requests but also to show that the facts supposed as the groundwork of his request must have been found on the evidence, and that no other facts could have been found which would make inapplicable the ruling of law asked for, parties in jury waived cases could not know, save in comparatively rare instances, that a grievous error of law had not been committed by the trial judge. When a case is tried without a jury, the judge occupies a dual position; he is the magistrate required to lay down correctly the guiding principle of law; he is also the tribunal compelled to determine what the facts are. When these duties are nicely analyzed, he ought as judge to -formulate the governing rules of law, and then, acting in place of the jury, he ought to follow these rules in deciding where the truth lies on conflicting evidence. In one essential particular only does he stand differently as to requests for rulings from a judge presiding over a jury trial, — he may refuse to grant a request for the avowed reason that it is immaterial or inapplicable in view of the facts found by him. When a request is presented such as in a jury trial ought to have been given, an exception to a refusal to grant it by a judge sitting without a jury must be sustained, unless the ground of refusal is distinctly stated or plainly appears in some way on the record and is such as to show that no harm has been done by the refusal, or unless it is obvious on the whole that no rights of parties have been endangered. Mere silent refusal to grant requests under these circumstances does not raise the presumption in favor of a trial court, which exists as to findings of fact made by it. This is no new principle of practice. The present judgment is simply an amplification of a rule inherent in the trial of jury waived cases, which has been more succinctly announced in earlier cases. Miller v. Robinson, 2 Allen, 610. Kettell v. Foote, 3 Allen, 212. Lane v. Boston Five Gents Savings Bank, 118 Mass. 260. Turner v. Wentworth, 119 Mass. 459, 464. It was stated by Chief Justice Holmes, in Clarke v. Second National Bank, 177 Mass. 257, 266, by Mr. Justice Loring in Jaquith v. Davenport, 191 Mass. 415, at 418, and by Mr. Justice Hammond in Chandler v. Baker, 191 Mass. 579, 585. To the same point see also Maynard v. Royal Worcester Corset Co. 200 Mass. 1, 5; *19Bangs v. Farr, 209 Mass. 339. There is nothing inconsistent with this view in Carnes v. Howard, 180 Mass. 569. The statute upon which the court acted in Insurance Co. v. Folsom, 18 Wall. 237, required a procedure unlike our own. This rule does not impair the efficiency of the Superior Court, nor restrict its power to administer justice promptly and completely. It is not a recurrence to technicality of practice. It does not invite or justify an unreasonable number of prayers calculated rather to entrap the unwary than to elucidate the principles involved. It does not require that exceptions be sustained when it is not apparent upon the whole that some substantial error injuriously affecting the rights of parties has been committed. It does not compel the judge to deal in detail with fragmentary or indecisive evidence, to be troubled by trivial requests, or to make a special finding, although, as was pointed out in 177 Mass. at p. 264, often it may prove helpful if the grounds of his action are explained. But it does require him, when refusing a request, founded upon evidence, to state expressly or by fair inference, either that the legal proposition presented is unsound or inapplicable, or that the facts upon which it is predicated are not found to be true. Failure in this regard affords reasonable apprehension that there has been a miscarriage of justice.
2. The defendant’s requests to the effect that the plaintiff could not recover upon the contract of March 7, 1900, were refused rightly. It does not appear to have been conceded that this contract when executed was not binding upon the parties. There was ample evidence that both parties supposed that the contract continued in force until August, and treated it as if in force. The only dispute about it was that the defendant asserted that there was a mistake in it as to the term of credit to be extended to it. It might have been found that the contention of the defendant in this regard, which was expressed by it in writing to the plaintiff, was accepted orally by the latter, and as thus corrected became binding upon the defendant, and available to the plaintiff, although not signed by both parties. The statute of frauds would be no defense under these circumstances. Beach & Clarridge Co. v. American Steam Gauge & Valve Manuf. Co. 202 Mass. 177, and cases cited at p. 181.
3. It was open for the trial judge to find that the contract *20was not annulled by mutual consent. The vote of cancellation by the board of directors of the plaintiff was not decisive, and may have been found in the light of all the testimony and the attendant circumstances to have been conditional upon the execution of a new one in substitution, a condition which was never fulfilled.
4. The mutilation of a copy of the contract by the plaintiff was only one factor, not necessarily conclusive by itself, and to be considered with all the others in ascertaining the intent with which the act was done. Attorney General v. American Legion of Honor, 206 Mass. 183. The general finding for the plaintiff involved the conclusions as matter of fact that the contract of March 7, 1900, as modified was binding upon the parties and had not been annulled or cancelled. In this no error appears.
5. There were no circumstances, which required a finding of such inability on the part of the plaintiff to carry on its business or intention on its part to sell out as to justify the defendant in abandoning its contract. The action of the plaintiff at most amounted to a determination to ascertain at what price its business could be sold for. It did not fairly warrant the inference of inability to go on with the contract. National Contracting Co. v. Vulcanite Portland Cement Co. 192 Mass. 247, and cases cited at p. 256.
6. The plaintiff is a manufacturer of textile machinery in England. William Firth, for some years previous to 1900, had the exclusive sale of the plaintiff’s machinery in America, and early in 1900 organized in the United States a corporation, of which he was the principal stockholder, president and manager, to take over his business. Under date of March 7,1900, a written contract was made between the plaintiff and the defendant, by which the plaintiff gave the defendant “the sole right to sell their machinery in the United States of America and the Dominion of Canada,” and the defendant undertook “ to sell efficiently and to appoint representatives to travel regularly in those countries visiting the existing mills and the districts in which mills may be erected for the purpose of procuring orders for all the various machines made by ” the plaintiff. The defendant further agreed not to engage in the sale of other similar machinery in *21the designated territory during the term of the contract, and the plaintiff agreed to do all its business in the same territory through the agency of the defendant. All the machinery was to be invoiced to the defendant as delivered, and was to be paid for by the defendant within a specified time, the defendant to conduct the business in its own name. The contract was to continue in force for five years, unless terminated sooner by the plaintiff on six months’ notice “ in the event of it being found that the William Firth Company cannot work the business as efficiently as it has been worked by William Firth.” The contract was terminated by the defendant without justification in August or September, 1900. The case was tried before a judge of the Superior Court without a jury, and a finding was made in favor of the plaintiff apparently based on the ruling that the plaintiff was entitled to recover the loss of profits on sales of machinery occasioned by the act of the defendant. We draw this inference from the refusal of the court to grant requests sixteen, seventeen, eighteen and nineteen of the defendant which cover this ground. The correctness of this ruling is challenged.
The fundamental principle of law upon which damages for breach of contract are assessed is that the injured party shall be placed in the same position he would have been in, if the contract had been performed, so far as loss can be ascertained to have followed as a natural consequence and to have been within the contemplation of the parties as reasonable men as a probable result of the breach, and so far as compensation therefor in money can be computed by rational methods upon a firm, basis of facts. Leavitt v. Fiberloid Co. 196 Mass. 440, 446. Wertheim v. Chicoutimi Pulp Co. [1911] A. C. 301, 307. When a claim for prospective profits is brought to the test of this principle, recovery can be had where loss of profits is the proximate result of the breach, and is such as in the common course of events reasonably might have been expected, at the time the contract was made, to ensue from a breach, and where it can be determined as a practical matter with a fair degree of certainty what the profits would have been. But profits cannot be recovered, when the contract interpreted in the light of all its surroundings does not appear to have been made in contemplation of such damages, or when they are remote, or so uncertain, contingent, or speculative as not to *22be susceptible of trustworthy proof. They must be capable of ascertainment by reference to some definite standard, either of market value, established experience or direct inference from known circumstances. Gagnon v. Sperry & Hutchinson Co. 206 Mass. 547, and cases cited at p. 555. Dennis v. Maxfield, 10 Allen, 138. This is simply a concrete application of the wider principle, which is frequently adverted to and which pervades the determination of all legal rights, to the effect that the complaining party must establish his claim upon a solid foundation in fact, and cannot recover when any essential element is left to conjecture, surmise or hypothesis. The difficulty is not so much in the statement of the general principle as in applying it. A comparatively insignificant incident may be in such combination with others as to lead to a conclusion in one decision apparently at variance with that reached in others. Each case must be decided on its own facts under this necessarily somewhat broad and comprehensive proposition.
This contract had a double aspect. In one respect it created the relation of principal and agent, and in another view it contemplated as between the parties purchases and sales. Looking at the latter first, it appears that while the plaintiff was to sell its machinery in the United States and Canada only through the defendant, the defendant was the buyer and was to make its profits by gains in resales, and was not to be paid by commissions. There was no agreement for any specific amount of sales. No maximum or minimum of aggregate annual transactions was stipulated. There was no obligation on the plaintiff to manufacture or on the defendant to take any definite number of designated machines. No prices were fixed. Whether there should be any sales depended upon a meeting of minds between the parties as to each article. Each sale would depend in the ordinary course of business upon the cost to the plaintiff of manufacturing, the profit demanded by it, the price which could be obtained in the American market, and the margin which the defendant might need to meet its expenses and a fair return upon capital invested and reasonable profit. No measure of remunerative profit for the plaintiff was settled, either by the contract or by the custom of the trade. It appeared that sometimes it had sold machinery to the defendant at a loss. There *23was evidence that the selling price of the plaintiff and its actual cost of manufacture bore no settled ratio to each other. The expenses of the defendant and its fair profit contdined inherently uncertain elements resting in large part upon the volumes of business done. The contract was silent as to any gouge of this, either by analogy to commissions, percentages, or otherwise. All these considerations, difficult if not impossible of proof, would enter into the minds of the parties in making each sale. The reported evidence shows plainly that there was great fluctuation in the demand by American cotton manufacturers for English-made machinery. This depended in material degree upon the mechanical ingenuity and business sagacity of competing American machine makers, and upon the prosperity of American cotton manufacturers. The conditions of both these branches of industry were subject to periods of depression and activity, as to which during the time covered by this contract there was much conflicting testimony. The variation in the annual sales by the plaintiff to the predecessor of the defendant in handling its American trade during the five years before 1900 had been from ¿£15,000 to ¿£140,000. The number of sales which the defendant would have been able to make to its customers was problematical. It could have made none, unless the prices fixed by the plaintiff upon its machines from time to time had been such as to enable it to attract American buyers. The defendant, although taking over at its incorporation the business conducted formerly by William Firth, had as a corporation no record of commercial achievement. Although Mr. Firth was the chief stockholder in the defendant, he was under no obligation to continue in its service, and might have sold his interest in it or left its employ at any time. The contract gave to the plaintiff no assurance that his ability would be retained in the business. It is conceivable that the contract might have been faithfully performed on both sides, and yet no important sales have been made. This might have arisen from á variety of circumstances liable to occur in ordinary trade. The plaintiff rests its claim for loss of prospective profits on two classes of evidence, — first, upon that showing the difference between its total sales in America for the five years next previous to the execution of the contract and its sales in America during the term of the contract, *24and computing upon this difference the profit which it claims it would have made; and, second, upon testimony to the effect that immediately after the defendant’s breach of contract its sales in America fell off greatly, as compared with those of the preceding seven months, until its new American agency was established. As to breaches of some contracts different in character from the one at bar and more explicit in their obligations, evidence of this nature might be important or even conclusive. Loughery v. Huxford, 206 Mass. 324. But the vagueness of this contract and the absence from it of elements vital to any binding or enforceable contract of sale have been pointed out. It must be construed as made and not reconstructed to meet an apparently unforeseen emergency. Perhaps no one' of these factors by itself would be decisive. But taking them as a whole, we are of opinion that the terms of this contract show that loss of profits was not cóntemplated as damages for a breach, and these, together with all the circumstances, both before and since its execution and breach, furnish a basis too insubstantial for the ascertainment of profits lost by the plaintiff. Moreover the interpretation we have adopted seems consonant with what may have been the intention of the parties. A new mechanical device may render obsolete machinery previously in wide use. A change in the tariff policy of governments may seriously affect the course of international commerce. These and other contingencies may have induced a contract of such elastic and indefinite terms as to leave each party somewhat free to act in view of altered conditions as they might arise, without being bound to hard and unyielding provisions. Noble v. Hand, 163 Mass. 289. Todd v. Keene, 167 Mass. 157. United Press v. New York Press Co. 164 N. Y. 406. Howard v. Stillwell & Bierce Manuf. Co. 139 U. S. 199.

McFarlan Carriage Co. 166 Ind. 123.
The case at bar is distinguishable from Speirs v. Union Drop Forge Co. 180 Mass. 87. In that case the contract was to keep *25an entire factory employed. Many of the prices for the staple articles to be manufactured were determined. Jn the value oi the manufacturing plant and the prices fixed were facts sufficient in the opinion of a majority of the court to support that action. But these elements are wanting in the plaintiff’s proof.
There is ground for the assessment of substantial damages, however, in the agency aspect of the contract. According to its terms the plaintiff was to have the active and intelligent service of the defendant, with a sufficient corps of salesmen, in pushing the sale of its products in the United States and Canada. That contract was broken by the defendant, whereby the plaintiff was deprived of that which it was entitled to receive. Thereupon it took the course, which it had a right to take in such an event, of establishing another agency in the United States and conducting its business through this substituted channel. Its reasonable expense incurred in repairing the loss cast upon it by the wrongful act of the defendant and in regaining the position acquired by it under its contract with the defendant is a legitimate element of damage and may be recovered. It is the direct result of the defendant’s breach of the contract, and no doubt is capable of approximately accurate proof. It was or should have been in the contemplation of the parties f as a consequence of the breach. C. W. Hunt Co. v. Boston Elevated Railway, 199 Mass. 220. Hanson & Parker v. Wittenberg, 205 Mass. 319. Erie County Natural Gas & Fuel Co. v. Carroll, [1911] A. C. 105, 117. The other exceptions become immaterial in view of the grounds upon which this decision rests.
It follows that these exceptions must be sustained, but only in respect to the assessment of damages. Hence the new trial must be confined to that issue.
So ordered.
