These are cross actions of contract arising out of the same transaction. They were tried together before an auditor and before a jury.
The plaintiff Cavanagh declares upon two counts. In the first count he alleges the making of a contract between the plaintiff and the defendant on October 23,1912, for the furnishing and driving of spruce piles for the foundation of the Boston Fish Market building on Pier No. 6, South Boston. In this count the plaintiff alleges in substance that he was induced to enter into this contract by misrepresentations made to him by officers of the defendant company; that relying upon such representations he performed *440a part of the work covered by the contract and continued at work until it was impossible to proceed further by reason of the soil in which the piles were to be driven being of a different character from what it was represented to be by the defendant. The plaintiff further alleges four breaches of the contract on the part of the defendant company, the first of which, namely, “that the defendant agreed to make certain excavations, which it refused and neglected to do,” is the only one argued. He then alleges that because of these breaches of the contract on the part of the defendant company, he has been forced to cease work under said contract and has suffered damages which he seeks to recover in this action. The second count for the same cause of action was amended before the trial in accordance with the terms of the auditor’s report, and now consists of an account for labor and material furnished by the plaintiff to the defendant to the amount of $14,323.12. The defendant’s answer is a general denial.
The plaintiff’s claim in the second action is set forth in a declaration containing two counts. The first alleges the making of a contract between the plaintiff and the defendant, Cavanagh, on November 22, 1912, under the terms of which the defendant undertook to furnish and drive all the piles required for the foundations for two buildings on the Boston Fish Market Pier in South Boston; the abandonment of the contract by- the defendant and an overpayment by the plaintiff to the defendant at the time he abandoned the contract; a specification of the damage which it alleges it sustained in completing the work, and a claim for the penalty provided by the contract in case of delay. The second count for the same cause of action is on an account annexed. The answer of the defendant was a general denial. And he further answered that the contract “was entered into under a mutual mistake of fact in the belief and understanding by both parties that the fill where the plaintiff [in the first action] was to drive piles under said contract was a mud and dirt fill, whereas in fact, unknown to both parties, said fill had been made to a large extent with stone rip-rap, boulders, concrete, brick and other debris, and was unsuitable for driving piles; wherefore this defendant says that in equity he ought to be absolutely and unconditionally relieved against the plaintiff’s claim and cause of action.”
Under the bid and acceptance, Cavanagh began work on Novem*441ber 5, 1912, and continued to perform work under that contract, or under it as modified by the printed formal contract dated November 12 and executed November 22, 1912, until February 5, 1913. On the 'last named day he wrote the company “I decline to further attempt to carry out my contract with you for furnishing and driving piles for the two buildings on Pier No. 6, South Boston, owing to conditions with which you are fully familiar. . . .” and thereupon ceased work and has done nothing further toward the completion of the contract.
At the trial before the auditor and, before the jury Cavanagh contended, and introduced evidence by which he sought to prove, that the original contract on the bid and acceptance as well as the written contract dated November 12 were void, because of fraud or because of mutual mistake; that all the contracts were abandoned by both parties; and that the contract of November 12, if ever in force, was broken by the company by its failure to make payments to Cavanagh and to excavate as it was required to do by the terms of the contract. At the close of all the evidence the presiding judge ruled that “there was no evidence to warrant submitting the case to the jury on the questions of mistake, abandonment, and breach of contract. . . .” The jury answered in the affirmative the question “Did Cavanagh waive breaches of the contract, if any, in the matter of payments?” The judge thereupon ordered a verdict for the defendant in the first case and for the plaintiff in the second case, and reported the cases to the Supreme Judicial Court upon the following terms and conditions: “ If the rulings made and directions and instructions given are correct, judgments are to be entered upon the verdicts as rendered. If upon all of the evidence the ruling of the court directing the verdicts was wrong, the verdicts are to be set aside and judgment is to be entered for the plaintiff in the case of Cavanagh v. Tyson, Weare & Marshall Co. in the sum of $14,323.12, with interest thereon from the date of the writ and in the case of Tyson, Weare & Marshall Co. v. Cavanagh, judgment is to be •s entered for the defendant. If the court erred in his rulings upon the admission or exclusion of evidence or in his instructions to the jury upon the issue which was submitted, then a new trial is to be had. If the court erred in his ruling upon the matter of variance between the proof and the pleadings in the *442second case, then a new trial is to be had in the second case.” We shall consider the contentions of Cavanagh in the order of his argument.
Upon the question of fraud or mistake the material facts are not in dispute, and are in substance that the Commonwealth of Massachusetts previous to September, 1912, had made a lease of Pier No. 6 to the Boston Fish Market Corporation for the purpose of building a fish market thereon; that in September, 1912, the Fish Market Corporation awarded a contract to the defendant and plaintiff company to build two buildings upon said pier called buildings No. 1 and No. 2; that the company previous to September 26, 1912, had sent to the plaintiff, in common with other pile drivers, a postal card requesting bids on the piling for the Boston Fish Market building with the statement, “plans and specifications at our office;” that bids were wanted before September 27, 1912; that the plaintiff had a conversation with Marshall of the. defendant company; that the plaintiff was told by Marshall that the defendant could get it done for $6.20 per pile, that if he wanted it at that price he could have it; that the plaintiff stated he “wanted to look into the job a little more,” that he wanted to go down and see the architects; that Marshall said “Go ahead down and see them; you know who they are; they are on the plans;” that the plaintiff then went to the office of the architects, Monks and Johnson; that Monies told the plaintiff to go to H. S. Adams, that Adams had full charge of the pile driving and was employed by the Boston Fish Market Corporation to look after that end of the work; that in consequence of what Adams said the plaintiff went to the office of' the Directors of the Port of Boston; that the plaintiff there saw plans and specifications for the construction of the pier and was- furnished with two copies of the plans; that these plans showed that the pier was filled in with mud and clay; that the plan reads “to be filled with dredged material from dock and trench;” that on the plan were records of borings showing only mud and clay in the dock and trench from which the fillings were taken. After examining the plan and specifications the plaintiff returned to the office of the defendant, told them he would take the job, and on the same day wrote a bid which was accepted. It reads “I will furnish and drive spruce piles according to plans *443and specifications in foundation of Boston Fish Market building, for the sum of Six Dollars and Twenty Cents ($6.20) each. I agree to deduct Thirteen Cents (13c) per foot for all piles driven less than 45' in length.” On November 5,1912, plaintiff began to' drive piles and immediately discovered that the fill was of a different character from that disclosed in the plans which he obtained from the Port Directors. He found that there was a top layer of .gravel which the plan did not show which caused the driving to be more difficult and the piles began to “broom out” at the bottom, a splitting, shattering or shredding of the pile caused by the end coming in contact with some solid substance. These obstructions turned out to be stone rip-rap of large dimensions, deposited there by the contractor who put in the fill for the Commonwealth.
The plaintiff did not discover that there were large stones in the fill until the last part of December, 1912, and there is no evidence to warrant a finding that the defendant had greater knowledge of the presence of rocks and boulders, or had greater opportunity óf acquiring knowledge of the condition of the fill than the plaintiff. There is no evidence whatsoever to warrant a finding that the defendant intentionally or innocently misrepresented to the plaintiff any fact concerning the nature of the fill. Nor is there evidence to sustain a finding that the defendant intentionally concealed any material fact concerning which it had reason to know the plaintiff was ignorant. When the bid was made and accepted for the driving of the piles, the plaintiff and the defendant were ignorant of the character of the fill, but each believed from what was shown on the plans in the office of the Directors of the Port that the fill where the piles were to be driven was composed of the material dredged from the dock and trenches around the pier, which was shown by the plans to be of soft material. Between the time of the acceptance of the bid and the execution of the formal instrument of contract, the plaintiff and the defendant had learned that the character of the soil was different from that shown on the plans but both remained ignorant of the presence of boulders and broken rock in the fill where the piles were to be driven.
Upon the facts the question presented is whether the erroneous belief of the plaintiff and the defendant is a mutual mistake of fact *444of sufficient importance to make the contracts void. Such result can follow only when the mistake relates to a fact which is of the very essence of the contract, the material element in the minds of both parties, and material in the sense that it is one of the things contracted about. Long v. Athol, 196 Mass. 497. Miles v. Stevens, 3 Penn. St. 21. 45 Am. Dec. 631, note. Steinmeyer v. Schroeppel, 226 Ill. 9. 117 A. S. R. 233, note.
In the case at bar the character of the fill through which the piles were to be driven was of importance only in the determination of the price to be demanded and paid for the performance of the work. Had the burden of performance proved less than anticipated it scarcely will be claimed that the defendant could in an appropriate action, have had relief from the contract through rescission or to recover any excess in payment over reasonable compensation. Yet, such would be the defendant’s right if the contract were void ah initia. Sherwood v. Walker, 66 Mich. 568. In the case at bar the mistake of fact is collateral to the essential thing contracted about and therefore does not invalidate the contract. Hecht v. Batcheller, 147 Mass. 335. See Long v. Athol, supra; Rowe v. Peabody, 207 Mass. 226; Young v. Holyoke, 225 Mass. 140. Winston v. Pittsfield, 221 Mass. 356.
The evidence would not warrant a finding that the contract was terminated by mutual assent on January 6,1913. The direction of the president of the company on that day to the plaintiff to “keep account of day work until the piers are excavated,” "to call it day work and keep account of it, at the time,” plainly relates to the claim of the plaintiff “for extra money to cover the extra expense of driving these piles” as is shown by the letter of the plaintiff dated January 1, 1913, and again by his letter of January 30, 1913, wherein he stated “ I do not see why there should be any reason to arbitrate on this line, and will, within a short time, send you my bill for extra work on Building No. 1, as far as the work has progressed.” Moreover, there is no sufficient evidence to warrant a finding that the president had the authority to agree to a' determination of the contract or to prove that the company had knowledge that its president had assumed the power to end the existing contract and to make a new and essentially different contract in substitution therefor. The finding of the jury that Cavanagh waived breaches, if any, in matters *445of payment excludes from consideration the argument that the company broke the contract upon which it now relies as to amount of payment, time of payment, and method of payment. It follows that the plaintiff had no right to cease to perform the work which he had agreed to perform under the contract because of any failure of the defendant to make payments in accordance with the terms of the contract.
We are of opinion that the failure to excavate under the conditions disclosed in the evidence was not the breach of a term of the contract, the performance of which was essential to the continuance of the work of Cavanagh. It follows that there was therefrom no right to repudiate the contract and the occasion does not demand a decision whether other remedies were given under the terms of the contract.
The requests, so far as they properly could be given, were fully covered in the charge to the jury. The instructions upon the issue submitted were accurate, clear and explicit, and had the sanction and authority of Farlow v. Ellis, 15 Gray, 229.
The evidence of Marshall was admitted rightly upon the issue of waiver of payments in accordance with the terms of the contract, as also upon the question whether Cavanagh had entitled himself to full payments under the contract.
The request to rule in the second action that there was a variance between the allegations and proof was denied rightly. The allegation of overpayment by the plaintiff to the defendant at the time the defendant abandoned the contract was an allegation of 'damages resulting from such breach, and as such was an immaterial and surplus allegation not necessary to sustain the action. It therefore need not be proved and should be treated as surplusage. Little v. Blunt, 16 Pick. 359, 365. Maxwell v. Maxwell, 31 Maine, 184, 187. Full performance of the oral agreement to excavate was not a condition precedent to the maintenance of the plaintiff’s right to the performance of the contract by Cavanagh, and the absence of such an allegation could be taken advantage of only by a demurrer.
We have examined the entire record and find no reversible error. In accordance with the terms of the report, judgments are to be entered upon the verdicts" as rendered.
So ordered.
