The essential facts as found by the court below are summarized as follows: Pursuant to an act of congress appropriating a stated sum for building two 'timber dry docks to be located at such navy yards as the secretary of the navy may indicate' (24 Stat. 484), the navy department on April 19, 1887, advertised for proposals for the building of two dry docks, to be located, one at the Brooklyn and the other at the Norfolk Navy Yard. The advertisement, while pointing out the general nature of the structures and their dimensions, contained no detailed plan of [172 U.S. 372, 373] the contemplated work, but announced that 'dry-dock builders are invited to submit plans and specifications with proposals for the entire construction and their completion in all respects,' and, moreover, it was said, 'bidders will make their plans and specifications full and clear, describing the kinds and qualities of the materials proposed to be used.' Besides, the advertisement stated that, 'for information in regard to the location and site of the docks, bidders are referred to the commandants of the Brooklyn and Norfolk Navy Yards.' On May 23d, pending the publication, the navy department addressed to the commandant of the Brooklyn Navy Yard the following letter:
Conforming to these instructions, Mr. Asserson, a civil engineer attached to the navy department, made an examination of t e soil, making borings to a depth of from 39 to 46 feet at a distance of 50 feet along a certain length in the middle of a portion of the ground of the navy yard. The result of these borings was delineated on a profile plan purporting to show the character of the underlying soil. It may be conceded that this plan indicated that the soil at the point referred to was stable and contained no quicksand. Simpson & Co., who were experienced dock builders, applied for information as to the proposed site, and a copy of the plan was handed to the firm. Simpson & Co. never knew of the above letter until after this suit was brought, and they did not intimate to any one that the bid which they proposed to submit for doing the work was to be conditioned on the existence [172 U.S. 372, 374] in the soil of the site to be selected of the characteristics indicated by the profile plan. It is true, however, that Simpson & Co., in making up their estimate and in preparing their specifications, took into view the presumed condition of the soil, and that the amount of their bid was made up upon the assumption that the soil underlying the dock would prove to be like that indicated by the plan.
In June, 1887, Simpson & Co. bid for the construction of the docks. The first two sentences of their proposal were as follows:
The price asked for the two docks was very near the sum authorized by congress to be expended for the purpose.
The specifications referred to were prepared by the firm, and contained the following recital:
Such other portions of the specifications as are material to be noticed are contained in the subdivision headed 'General Construction,' and are as follows: [172 U.S. 372, 375] 'Piles. All foundation, brace, and crosscap piles shall be of sound spruce or pine, not less than twelve inches diameter at butt and six inches at top, and of such length as may be required for the purpose, and well driven to a firm bearing.
... ... * *
The bid was accepted, and a written contract was executed. In this contract, recital was made of the advertisement for proposals, the making of the bid with accompanying specifications, a d the acceptance thereof; and these documents thus referred to were annexed, and made a part of the contract.
The contract contained in its first clause the following:
The seventh clause of the contract is stated in the margin. 1
In addition, penalties were stipulated for delay in the performance of the work, and a discretion was vested in the secretary of the navy to allow an extension of time for any failure to complete the dock within the contract period.
The work was to be paid for in installments, upon proper estimate, as it progressed, and 10 per cent. was to be retained by the government until its final completion.
The construction was commenced in Vovember, 1887, and [172 U.S. 372, 377] after considerable labor had been expended and material used, 'about August 31, 1888, it first became apparent that a portion of the dry-dock structure had sunk and moved inward towards the excavation, and had thereby sustained damage, and that this damage was caused by encountering a stratum of water-borne sand in the excavation, which flowed from beneath, and undermined the banks forming the side of the dock excavation.' Thereupon it was ascertained that the 'sand stratum hereinbefore described underlay the entire area of the site of the dock, and, beginning at a depth of from twenty-six to thirty feet below the grade of the side, extended to a depth of seventy feet below the same. ... Between August, 1888, and October, 1889, portions of the dry-dock structure completed by the plaintiffs during that period continued to settle and move inward towards the excavation. ... This was caused by the presence of the said sand stratum which continued to undermine the side of the dry-dock excavation; hence portions of the dry-dock structures were destroyed or greatly damaged. ... During the period aforesaid the sand flowed into the excavation made for the dry dock, delaying the completion thereof, and increased the cost of the dock. The character of the soil underlying said site was not as it appeared in the profile plan in the report of the said Asserson, in so far as the said sand stratum is concerned, and both parties were surprised in encountering the difficulty and expense caused by the presence of the said sand stratum. After the discovery of the said sand stratum as aforesaid, Commodore Harmony, chief of the bureau of yards and docks, inspected the work upon the site of the dry dock, and directed the plaintiffs to complete the dock. By reason of the presence of the said stratum of sand, and the difficulties caused thereby, the completion of the dock was delayed seven months.'
As the work progressed, estimates thereof were made as required by the contract, and the amount, less the 10 per cent. reserved, was regularly paid to the contractors. Moreover, additional piling being required, a supplementary estimate thereof was made, the price for the same fixed, and the amount was paid to the contractors.
The dock was completed May, 1890, and a board was appointed to inspect it, and, upon a favorable report, the dock was finally received by the United States; and a claim for 10 per cent., which had been retained on the amount of the whole work, was presented by the contractors, and was audited and paid, and a full and final receipt was given of June 17, 1890. The relations between the contracting parties in reference to the dock then terminated, and no question was raised between them as to any extra claim or allowance, until nearly three years after the final settlement ( that is, on April 11, 1893), when the attorneys of the Simpson Dry-Dock Company, as assignees of the claim of J. E. Simpson & Co., addressed a letter to the secretary of the navy, claiming for extra services rendered and material furnished in the construction of the dry dock. This claim was based upon the theory that the site of the dry dock was not 'available, owing to the unfavorable and unstable character of the soil,' and, hence, that the government was liable to the contractors in the sum of $174,322. This demand not having been complied with, the present suit was brought; the claim being for a much larger sum than that stated in the letter of the attorneys, and being made on behalf of the members of the firm of J. E. Simpson & Co., as owners thereof. [172 U.S. 372, 379] James H. Hayden and Jos. K. McCammon, for appellants.

Mr. Justice WHITE, after making the foregoing statement, delivered the opinion of the court.
Considering the facts above stated, it is at once apparent that the claim against the United States can only be allowed upon the theory that it is sustained by the written contract, since, if it be not thereby sanctioned, it is devoid of legal foundation. The rule by which parties to a written contract are bound by its terms, and which holds that they cannot be heard to vary by parol its express and unambiguous stipulations, or impair the obligations which the contract engenders by reference to the negotiations which preceded the making of the contract, or by urging that the pecuniary result which the contract has produced has not come up to the expectations of one or both of the parties, is too elementary to require anything but statement. The principle was clearly announced in Brawley v. U. S., 96 U.S. 173 , where it was said:
Before measuring the claim by the contract, it is essential to clearly define the exact predicate upon which the demand necessarily rests. Reducing all the contentions of the claim- [172 U.S. 372, 380] ant to their ultimate conception, they amount simply to the proposition that he United States by the written contract guarantied the nature of the soil under the site of the proposed dock, and assumed the entire burden which might arise in case it should be ascertained, during the progress of constructing the dock, that the soil under the selected site differed, to the detriment of the contractor, from that delineated upon the profile plan which had been made by an officer of the United States. Considering the contract itself, it is clear that there is nothing in its terms which supports, even by remote implication, the premise upon which the claimants must rest their hope of recovery. The contract imposed upon the contractors the obligation to construct the dock according to the specifications, within a designated time, for an agreed price, upon a site to be selected by the United States. We look in vain for any statement or agreement, or even intimation, that any warranty, express or implied, in favor of the contractor, was entered into concerning the character of the underlying soil. The only word which it is claimed supports the contention that a warranty was undertaken by the United States as to the condition of the soil is the statement found in the opening portions of the specifications, that the dock was to be built in the navy yard upon a site which was 'available,' and great stress was laid in the argument at bar upon this word. But the word 'available' intrinsically has no such meaning as that sought to be given it. It certainly cannot be said that the site selected for the dock was not available for the purpose, since one has been actually erected thereon. It is conceded in argument that the word 'available' has not naturally the meaning which must be attributed to it in order to support the contention that there was a warranty as to the condition of the soil. But it is said the word should be construed as having such signification, because bidders were referred to the commandants of the navy yards for information as to the sites of the docks, and the plan showing the result of the examination made upon a portion of the yard was submitted to them. In other words, while admitting the rule that the contract is the law of the case, and [172 U.S. 372, 381] that the rights and obligations of the parties are to be alone determined from its context, the argument invokes a departure from that rule, and asks that the contract be so construed as to create a right in favor of one of the parties in conflict with the natural significance of the language of the contract, because of antecedent negotiations which took place between the parties.
Aside from the contradiction which this contention involves, the meaning now claimed for the word 'available' cannot be adopted without departing from the intention of the parties as manifested by the terms of the contract, and the documents forming part of it; and such meaning cannot, moreover, be sanctioned without doing violence to the context of the contract. The advertisement for bids was made in April, 1887. The bid and specifications which accompanied it were drawn by the firm, and were submitted in June, 1887. The advertisement to which they were an answer called for a full and explicit statement of what was proposed to be done by the contractors, and what were the requirements upon which they expected to rely. The contractors were experienced and competent dock builders. If it had been their intention to only undertake to build the dock for the price stipulated, provided a guaranty was afforded them by the United States that the soil upon which the dock was to be constructed was to be of a particular nature, conforming to a plan then existing, a purpose so important, so vital, would necessarily have found direct and positive expression in the bid and specifications, and would not have been left to be evolved by a forced and latitudinarian construction of the word 'available,' used only in the nature of a recital in the specifications, and not in the contract. The fact that the bidders knew that a test of the soil in the yard had been made, and drew the contract providing that the dock should be located on a site to be designated by the United States without any express stipulation that there was a warranty in their favor that the ground selected should be of a defined character, precludes the conception that the terms of the contract imposed such obligation on the government, in the absence of a full and clear expres- [172 U.S. 372, 382] sion to that effect, or at least an unavoidable implication. This is made clearer by other portions of the contract and specifications.
The seventh paragraph of the contract contained a stipulation that 'the construction of the said dry dock and its accessories and appurtenances herein contracted for shall conform in all respects to and with the plans and specifications aforesaid.' Now, the recital in the specifications as to an 'available' site is only contained in the opening clause thereof, and naturally suggests only that it relates solely to some place in the yard which should be selected, in the discretion of the government, suitable for the erection of a dry dock. So, also, in the specifications as to the materials to be furnished, which follow the recital as to the location of the dock, there is not contained a word implying that a particular piece of ground in the navy yard, having soil of a specially stable character, was to be the site on which the dock was to be placed. The contrary, however, is clearly implied from the provisions as to foundation and other piling which were to be used in supporting and inclosing the structure. The foundation, brace, and cross- cap piles, it was stipulated, were to be 'of such length as may be required for the purpose, and well driven to a firm bearing,' while it was stipulated that the sheet piling should be 'driven close and to such depth as may be found necessary to make good work'; and these provisions were followed by a clause reciting that, 'should the character of the bottom be found such as to warrant a modification of the pile system of floor construction, a concrete bed of not less than six feet in thickness may be substituted for the foundation piles.'
Light is thrown upon the plain meaning of the contract by the conduct of the parties in the execution of the work. It is not pretended that when the character of the subsoil was discovered the slightest claim was preferred that this fact gave rise to an extra allowance. The fact is that the contractors proceeded with the work, obtained delay for its completion, made their final settlements, and received their last payment, without ever asserting that any of the rights which they now claim were vested in them. Without deciding that such con- [172 U.S. 372, 383] duct would be decisive, if the claim was supported by the contract, it is nevertheless clear that it affords a just means of adding forceful significance to the unambiguous letter of the contract, and the self- evident intention of the parties in entering into it.
[ Footnote 1 ] The construction of the said dry dock and its accessories and appurtenances herein contracted for shall conform in all respects to and with the plans and specifications aforesaid, which plans and specifications are hereunto annexed, and shall be deemed and taken as forming a part of this contract, with the like operation and effect as if the same were incorporated herein. No omission in the plans or specifications of any detail, object, or provision necessary to carry this contract into full and complete effect in accordance with the true intent and meaning hereof shall operate to the disadvantage of the United States, but the same shall be satisfactorily supplied, performed, and observed by the contractors, and all claims for extra compensation by reason of, or for or on account of, such extra performance, are hereby, and in consideration of the premises, expressly waived; and it is hereby further provided, and this contract is upon the express condition, that the said plans and specifications shall not be changed in any respect, when the cost of such change shall exceed five hundred dollars, except upon the written order of the secretary or acting secretary of the navy, and, if changes are thus made, the actual cost thereof, and the damage caused thereby, shall be ascertained, estimated, and determined by a board of naval officers appointed by the secretary of the navy, and the contractors shall be bound by the determination of said board, or a majority thereof, as to the amount of increased or diminished compensation which they (the contractors) shall be entitled to receive, if any, in consequence of such change or changes; it being further expressly understood and agreed that such working plans and drawings, and such additional detailed plans and specifications as may be necessary, shall be furnished by and at the expense of the contractors, subject to the approval of the chief of the bureau of yards and docks, and that if, during the prosecution of the work, it shall be found advantageous or necessary to make any change or modification in the aforesaid plans and specifications, such change or modification must be agreed upon in writing by the contractors and by the officer in charge of the work,-the agreement to set forth fully the reasons for such change and the nature thereof, and to be subject to the approval of the party of the second part.
