INFORMATION. The object of the contract to be entered into under these specifications is to construct the concrete base or pillar of a light and fog-signal station, to be erected on Mile Eock, entrance to San Francisco Harbor, Cal. This station is to consist of a monolith concrete base, enclosed by steel plates, resting on the rock at the level of mean high water. This monolith is to be 34 feet high, and will cover an area of 704 square feet. On the top of this there will be a four-story tower made of structural steel, and surmounted by a lantern. The station will be provided with machinery, in duplicate, for a 10-inch fog whistle, to be operated by compressed air. The motive power of the compression machinery will be some form of mineral oil engine. Accommodations are to be provided for three keepers. The focal plane of the light will be 84 feet 3 inches above the datum plane, which is at the mean of lower low water. LOCATION. Mile Eock is about one half a mile inside a line joining the outer heads of San Francisco Harbor, and three eighths of a mile from the nearest point on the south shore. It rises nearly vertical out of the water, which is from forty to fifty feet deep. It has an area at the level of mean high water of about 1,000 square feet, and its highest point is sixteen feet above datum plane. About one hundred and sixty feet from the rock, on the inshore side, there is another smaller rock extending above high water, which may be found useful in the course of construction, for mooring purposes. Between these there is navigable water. The mean rise and fall of the tide in this locality is about six feet. The tide on both ebb and flood is very swift, and the duration of slack water small. The ordinary summer afternoon winds of the locality will interfere with the construction work during its early stages that is, until a height of five or six feet above the foundation is reached. Parties intending to submit proposals for the construction of this station should visit the locality and study the difficulties to be contended with. CHABACTEB OF MATEEIAL AND WOEKMANSHIP. The importance of this work, and the exposed position in which it is to be done, make it imperatively necessary that only the very best of materials and work- manship enter into the construction of the station. It must, therefore, be distinctly understood that these requisites will be insisted upon. CONDITIONS. The right is reserved to reject any or all bids, and to waive informalities. These specifications are intended to include everything that pertains to the preparation of the rock to properly receive the structure, and to its erection to the top of the concrete pillar, all outside plating, all bolts, fastenings, etc., necessary to the landing of material and supplies at the station which should be properly be placed in this part of the structure, all doors and windows, and pipes through the concrete and rock down to such depths as may be required, and all fastenings to the rock, and steps forming the landing; also such rings and eye-bolts on Little Mile Eock and in the concrete structure as may be required for mooring purposes. 6 CEMENT. All cement for the > concrete work will be furnished by the Government MATEEIALS FURNISHED BY THE GOVERNMENT. All materials and parts of the structure furnished by the Government will be transported from cars or place of storage in San Francisco by the contractor, and cared for by him until placed in position at the station. PLANT, ETC. The contractor is to furnish all plant, labor and material, except that which is herein specified as to be furnished by the Government, necessary for the complete and substantial execution of everything described, shown, or reasonably implied in the drawings and specifications. The contractor will cover and protect the work and material, and be responsible for all damage thereto until the final completion of the contract. He will clear away, from time to time as may be necessary, all dirt and rubbish resulting from the work, and on the final completion he will thoroughly clean all floors and windows, remove all debris, and leave the premises in good order. DRAWINGS AND SPECIFICATIONS. The drawings and specifications are intended to correspond and be illustrative of each other, and any work appearing in one and not in the other is to be done the same as though included in both. No advantage will be taken by the contractor of any omission of information in the specifications or drawings, as full explanations or detailed drawings will be given for any part of the work not sufficiently shown or understood. The contractor will substitute at his own cost, and without delay, satisfactory work and material for any and all that may be rejected, and will make good any work that may be disturbed thereby. SUPERVISION OF WORK. The authorized agents of the Light-House Engineer are to have access to the work and material at all times. An agent will be appointed to superintend the work, and in case of a difference between him and the contractor, the decision of the Light-House Engineer shall be final. This agent shall be allowed the privilege of going to and from the work on such boats and by such means as the contractor may provide for himself or his material and labor, whenever necessary, without expense to the Government. The contractor will furnish without expense to the Government such assistance in labor, tools and materials, as may be required in marking lines and fixing points upon the rock, which are necessary to his work. The Light-House Engineer may, by written notice, require the contractor to dismiss at once such workmen or persons in his employ as he may deem incompetent, careless, or injurious to the work, and such individual may not again be employed on the work. EXTRA WORK, ETC. Should any extra work or changes be found necessary during the progress of the work, the value of such work or changes shall be the subject of a written agreement before being commenced, between the Light-House Engineer and the contractor, subject to the approval of the Light-House Board. All work of every kind and description must be done and completed to the satisfaction of the Light-House Engineer. DETAILED DESCRIPTIONS. SHAPE OF PLAN. The outline of the plan of the structure will be formed by two segments of equal ellipses with corresponding axes at right angles to each other, placed so as to form a symmetrical figure, the distance between the centers of the ellipses being 12 feet 6 inches, and the segments being joined by right lines tangent to both. The major and minor axes of the two ellipses being 25 feet and 21 feet respectively. This plan will be adjusted to the rock and the structure located thereon as shown upon Plate 1 of the drawings accompanying these specifications. The base of the structure will be at the height of 6 feet above the plane of a mean of lower low water as established and marked upon the rock; this height being practically that of mean high water. The pillar is terminated at the top by a moulded cap extending out all around, two feet beyond the general line of the face. Plate XI, Fig. 1. EXCAVATION. From the periphery of the base inward for a distance of 3 feet the rock will be excavated where necessary down to reference 6, mean high water, and carefully prepared for the concrete. It will be permitted to use only very small charges of powder, and these only in localities where the rock to which the concrete is to be joined will be in no danger of being shattered or disturbed. The Light-House Engineer, or his representative, is to be the exclusive judge as to where explosives may be used, and as to the quantity. It may be expected that practically all the excavation will be done by gadding. No concrete will be placed until its foundation has been satisfactorily prepared. The lower part of the stair well and the pump room adjoining, and a part of the passage out to the landing steps will be in excavation. A small amount of excavation will be required outside the periphery and below reference 6, to accommodate the landing stairs. Should there be points at which a suitable foundation is not found at the level adopted, at these the contractor will be expected to extend the excavation lower. There will be approximately 70 cubic yards of excavation. STEEL PLATING, ETC. The concrete is to be enclosed in a casing of tank steel, % inch thick, in sheets 3 feet high by 8 feet in length, or longer if more convenient to the contractor. The edges of the plates are to be at right angles to each other. The laps of the horizontal joints to be 2 inches, the vertical joints to abut, with straps 3 inches wide on the inside. The vertical joints to be practically at the middle of the upper and lower plates. Plates to be arranged alternating out and in, as shown upon the drawings. Rivets to be %-inch diameter with pitch 4 inches for vertical seams and 6 inches for horizontal. Holes to be punched in plates so that rivets will draw fair. There will be %-inch bent iron bolts, 1 foot in length, with heads on the outside, placed about 3 feet apart, the bolts in one row to be opposite the intervals of the next adjoining, for the purpose of anchoring the plates to the concrete. The third row of these stay bolts from the bottom to be provided with eyes one inch in diameter. The plating will extend into the entrance gallery as far as the door recess. Openings will be provided through the plating at the port holes and at other places wherever necessary. One object of this plating is to form an outer mould for the concrete, and it is to be put in place only as the concrete can be filled in back of it. All plates to be punched, bent, fitted and suitably marked in the shops of the contractor before being sent to the rock. For the purpose of holding the lower edge of the plating in place, iron bolts 1 inch in diameter and 18 inches long will be firmly fastened into the rock at intervals of 3 feet, so as to permit the plating to pass them alternately inside and out. These bolts to extend 1 foot into the rock and 6 inches above it. Around the top edge of the concrete there will be an angle iron 3% inches by 3% inches by 1/2 inch, fastened to the concrete by %-inch anchor rods 18 inches long, one on each side of the chain posts, and one midway between each two posts. This angle will have the corner rounded to curve with a radius of % inch. Plate XI, Fig. 1. Holes will be left 6 inches by 6 inches by 6 inches about 6 feet apart, for the insertion of chain posts. Plate XI, Fig. 1, and Plate VI, Fig. 1. Conical holes 4 inches by 4 inches at top and 6 inches by fi inches at bottom, 2 feet deep and 4 feet apart, to be left as shown on Plate XII, Fig. 1, for the insertion of bolts for holding down the iron superstructure. CONCRETE. No care nor expense must be spared to make this the very best that can be manufactured. The cement, which will be furnished by the Government, will be of a well-known and long-established brand, the best that can be obtained in the San Francisco market. This to be taken by the contractor from the place where stored bv the Government. 8 The sand must be clean and sharp, and gravel and broken stone clean, hard, and free from all impurities of every character whatever. The broken stone must be in size such as to go through a screen with 1 inch meshes. Bidders must submit with their proposals samples of the sand, gravel, and broken stone that they propose to furnish. The concrete will be mixed in the proportions of one cement, two sand, and four broken stone or coarse gravel, by measurement; with only sufficient water to insure that the materials may be worked with reasonable ease. The water to be added through a hoze nozzle, or other form of sprinkling arrangement, after the materials have been thoroughly mixed dry. The whole mass to be again thoroughly mixed. The custom of throwing water upon the concrete at the place of deposit to make it work easily will not be permitted. No more than thirty minutes must elapse from the time that the water is first added to the concrete until the tamping is completed. The concrete must be deposited in layers of about 4 inches and well rammed. The top of each layer to be roughened and prepared to receive the succeeding one so that the junction between the two will be perfect and no seams or interstices visible. In placing new concrete on that thoroughly set great care must be taken to roughen the surface of the old, clean it thoroughly and do all things necessary to insure that the junction will be perfect as possible. All forms and surfaces against which the concrete is to be placed should be rigid so as not to shake during the process of packing. After the concrete is in place and the forms removed, all exposed surfaces must be pointed and made smooth and uniform by being covered with a thin coating of mortar composed of one part sand and one part cement, well rubbed on with a wooden trowel. In some parts of the structure the proportions of the material in the concrete may be slightly varied at the discretion of the Light-House Engineer. In the upper part of this structure there will be provided a store room having a height of 7 feet 10 inches, with walls 4 feet thick. These walls to be pierced by six holes for the admission of light, which are to have an outside diameter of 2 feet and a diameter of 20 inches at the window frame. Inside of windows a rectangular recess; dimensions on drawings. Port hole windows, glass one inch thick, bronze frame, each fastened to concrete by four bronze screw bolts with nuts imbedded in concrete. Plate XI, Figs. 1 to 7. CISTEEN. Under the floor of the store room a cistern for fresh water, 8 feet diameter and 10 feet high, will be provided. The top of this to be covered with concrete having bars of %-inch twisted iron imbedded in it. A hole will be left in this top for entrance to the cistern, about 20 inches in diameter, and provided with a suitable frame and cover.

The second and final payment, 28 including the retained percentage, shall be made when the work contemplated by the contract is all entirely 29 completed to the satisfaction of the Light-House Engineer, after deduction of such amounts as may have accrued 30 in consequence of delay in completion, as described in the specifications. 31 And it is expressly understood and agreed that, as each payment hereinbefore stipulated is made, possession of 32 the material, labor and articles which are paid for by such payments shall pass to, and the title thereto shall be 33 vested in the United States. 34 If, in any event, the party of the first part shall delay or fail to commence the delivery of the material or 35 the performance of the work specified herein, or shall, in the judgment of the officer of the Light-House Board 36 in charge, fail to prosecute faithfully and diligently the work in accordance with the specifications and require- 37 ments of this contract, then, in either case, the party of the second part, or his successor, shall have power, with 38 the sanction of the Light-House Board, to annul this contract by giving notice in writing to that effect to the party 39 (or parties, or either of them) of the first part; and the party of the second part shall be thereupon authorized, if 40 an immediate performance of the work or delivery of the materials be in his opinion required by the public 41 exigency, to proceed to provide for the same by open purchase or contract, as prescribed in section 3709 of the 42 Revised Statutes of the United States; but the party of the first part shall remain liable to the party of the second 43 part for the damages occasioned to him by the said noncompliance, delay, or negligence: Provided, however, That 44 if the party (or parties) of the first part shall by freshets, ice, or other force or violence of the elements, and by 45 no fault of his or their own, be prevented either from commencing or completing the work, or delivering the 46 materials at the time agreed upon in this contract, such additional time may, in writing, be allowed him or them 47 for such commencement or completion as, in the judgment of the party of the second part, or his successor, shall 48 be just and reasonable, any additional expense incurred by the United States on account of inspection or otherwise 49 during the period of extension to be deducted from the contract price of the work; but such allowance and extension 21 50 shall in no manner affect the rights or obligations of the parties under this contract, but the same shall subsist, 51 take effect, and be enforceable precisely as if the new date for such'commencement or completion had been the date 52 originally herein agreed upon. 53 It is further understood and agreed that in case of failure on the part of the party of the first part to complete 54 this contract as specified and agreed upon, that the said United States shall have the right to recover any or all 55 damages incurred by reason of said failure by the party of the first part, and shall also have the right to recover 56 whatever sums may be expended by the party of the second part in completing the said contract in excess of the 57 price herein stipulated to be paid to the party of the first part for completing the same. 58 And it is further stipulated and agreed that no Member of or Delegate to Congress shall be admitted to any 59 share or part of this contract or agreement, or to any benefit to arise therefrom;

(28) Directions as to Execution of Contracts. 1. The contract papers proper, comprising the specifications, drawings, if any, contract, bond, bondsmen's oaths, justification by corporate surety when a guaranty or surety company is upon the bond of the contractor, instead of two individual sureties and certificate of solvency, should be made in quadruplicate, and each copy should be the exact counterpart of the others, so that any one of them may be used as an original. 2. Before signatures are appended to the papers, all dates should be written in, and all remaining blank spaces ruled out, with ink. 3. Interlineations and erasures are to be avoided when possible; but when they are unavoidable, either in the specifications, the contract, or the bond, they should be noted, word by word, immediately above the signature of the witnesses, specifying the number of each line where they occur; and certificates should be made that each specific correction or alteration was made before the contract was signed. 4. The full name and the residence of each signer of a contract and bond should be written in the body of the contract and bond. 5. When firms contract, the name of the firm and the full name of each member thereof should be written at the beginning of the contract; for instance, " Smith, Brown & Co., of the city of New York, a firm composed of John S. Smith, Charles B. Brown, and John W. Eobinson." The contract should be signed in the firm name without seal. The bondsmen must not sign the contract. 6. When an incorporated company enters into contract, the corporate name of the company should be written at the beginning of the contract and bond; for instance, " The Smith and Brown Dredging Company, a corporation created by and existing under the laws of the State of New York, of the city of New York, in said State." The contract and bond should then be signed with the corporate name by a person duly authorized to do so, sealed with the corporate seal, and a certificate, under the corporate seal of the company, showing the signer's authority to sign sealed instruments in its behalf, should be appended to one copy of the contract. In the event that the corporation has no corporate seal, a seal of wax or wafer should be affixed to the bond and adopted and used for the time being as the seal of the corporation, and the fact that such corporation has no corporate seal should be shown by affidavit duly made before a notary public, whose official seal should be affixed thereto. 7. A bond for the faithful performance of the contract will be required. Seals of wax or wafer should be affixed to the signatures of principals and sureties, if individuals; and corporate seals should be affixed as required by Rule 6. The bond should bear the same date, or a date subsequent to that of the contract. 8. An individual or individuals, doing business under a firm name, should sign the bond in his, or their, individual names. Firm names should not be signed to the bond. 9. Each signature to a contract or bond should be made in the presence of at least one witness, who should sign his name as a witness. (29) 30 10. A firm will not be accepted as a surety, nor will a partner be accepted as a surety for a copartner, nor for a firm of which he is a member. An officer of a corporation will not be accepted as surety for such corporation. In no case will a married woman be accepted as a surety, and when an unmarried woman (widow or spinster) is given as a surety, she must be described as such in the body of the bond. 11. When a person signs a contract or bond as the agent or attorney in fact of another person, evidence of his authority to sign the same should be furnished. The authority to execute an instrument under seal should itself be under seal, and it should also be duly acknowledged before an officer empowered to take acknowledgments. 12. There must be not less than two individual sureties, but one corporate surety duly qualified under the Act of Congress of August 13, 1894, may be accepted as sole surety. The contractor and sureties should sign (execute) each bond. Each member of a firm should sign the bond personally or by attorney; in the latter case, a certified copy of the power of attorney under which the signature is made should be appended to the contract. Each surety must qualify in double the amount of the bond. This direction applies to corporate as well as individual sureties, and corporate sureties should also attach to each bond a copy of the last statement of their assets and liabilities, as rendered pursuant to Section 4 of the Act of Congress of August 13, 1894. Each surety should make and sign an affidavit of the amount he is worth over and above all debts and liabilities, and such exemptions as may be allowed by law. Sureties, other than corporate sureties, should state under oath that they are not responsible as sureties on any other bond, or, if so liable, the amount of such liability. When the required oath is taken before a justice of the peace, a certificate in the usual form should be appended, attesting his official character. This inconvenience can be avoided by ha.ving the oath taken before a notary public, in which case the notarial seal must be affixed or impressed. 13. A judge or clerk of a United States court, a United States district attorney, United States commissioner, postmaster, or a judge or clerk of a State court of record, with the seal of said court attached, should certify that the -Sureties are sufficient to pay the penalty of the bond, and except in the case of a judge of a United States court, or a United States attorney, if the person certifying has no seal, his official character should be duly certified. The foregoing does not apply to corporate sureties who have complied with Rule 12 of these directions relative to evidence of their ability to meet double the entire .obligation of their bond. 14. Corporate sureties, duly qualified to do business, under the Act of Congress of August 13, 1894, and who have filed with the Solicitor of the Department of Commerce and Labor evidence of their authority to do business, from the Department of Justice, need not furnish a certificate of such authority with each contract on which they are bondsmen. 15. When contracts and bonds have been thus prepared, and signed and sealed by the officer making them, in behalf of the United States, they should be forwarded to the Board for approval. 16. When approved by the Board and by the Secretary of the Department of Commerce and Labor, two copies will be returned to the officer making the contract, one for delivery to the contractor and the other for file. U. S. LIGHT-HOUSE ESTABLISHHENT. CONTRACT FOR Construction of a Structural Steel Tower FOR A Light and Fog- Signal Station ON MILE ROCK, ENTRANCE TO SAN FRANCISCO HARBOR, CALIFORNIA. ADVERTISEMENT. OFFICE OF U. S. LIGHT-HOUSE ENGINEEE, TWELFTH DISTRICT, Room 91, Flood Building. SAN FRANCISCO, CAL., , 1904. SEALED proposals will be received at this office until 12 o'clock, noon, Standard time, on , 1904, and then publicly opened, for the construction of a tower built of structural steel upon a concrete base which will be prepared for its reception, for a light and fog-signal station on Mile Rock, entrance to San Francisco Harbor, Cal. Plans and specifications, together with forms of proposal and all other necessary information, may be obtained on application to this office. The right is reserved to reject any or all bids, and to waive informalities. THOS. H. HANDBUKY, Lieut. Col., Corps of Engineers, TJ. S. A., Engineer 12th Light-House District. SPECIFICATIONS. INFORMATION. The object of the contract to be entered into under these specifications is to obtain, on the part of the Government, a tower built of structural steel upon a concrete base which will be prepared for its reception, on Mile Eock, at the entrance to San Francisco Harbor, California. This tower will be four stories high, surmounted by a lantern, and will be used as a light and fog-signal station. The station will be provided with machinery for a 10-inch fog whistle which will be operated by compressed air. The motive power of the compressing machinery will be some form of mineral oil engine, in duplicate. Accommodations are to be provided in the tower for three keepers and a reasonable supply of provisions and oil for operating the station. The top of the concrete base on which the tower stands is 40 feet above the plane of a mean of lower low waters. The focal plane of the light will be 84 feet 3 inches above this datum. LOCATION. Mile Rock is about one half a mile inside a line joining the outer heads of San Francisco Harbor, and three eighths of a mile from the nearest point of the mainland to the southward. It rises nearly vertically out of the water, which is from forty to fifty feet deep. About one hundred and sixty feet from the rock on the inshore side there is another smaller rock extending above high water, which may be found useful in the course of construction for mooring purposes. Between these there is navigable water. The mean rise and fall of the tide in this locality is about 6 feet. The tide on both ebb and flood is very swift, and the duration of slack water short. The ordinary summer afternoon winds of the locality may create waves which will prevent landing directly from a boat on the rock. Parties intending to submit proposals for doing this work should visit the locality and study the difficulties to be contended with while carrying on their operations. CHARACTER OF MATERIAL AND WORKMANSHIP. The importance of this work and the exposed position in which it is to be placed, make it imperatively necessary that only the very best material and work- manship enter into its construction. It must, therefore, be distinctly understood that these requisites will be insisted upon. The right is reserved to reject any or all bids, and to waive informalities. CONDITIONS. The contractor for this work is expected to furnish all the material and labor necessary to place the structure hereinafter described upon the concrete base, furnish all machinery, except such as will hereafter be described as to be furnished by the United States, and make all connections to the same as are necessary to a fog-signal and light station, as is contemplated by these specifications, complete in every respect and in good (5) 6 working order. The contract price will include the cost of everything connected with the station, with the exceptions mentioned, that is not included in the work done in connection with the concrete base, which in general may be described as including all that portion which lies on and above the floor of the store room in the concrete base, and the small pump located in the pump room, with its connections. MATERIAL FURNISHED 13Y THE GOVERNMENT. The Government will furnish the lens and its stand, which are to be placed in the lantern-, two 20 H. P. Hornsby-Akroyd engines, with air compressors attached, but no piping, reservoirs or other necessary accompaniments; and two Crosby automatic governors. All of which must be transported from the cars or place of storage in San Francisco, CaL, by the contractor, and cared for by him until placed in position at the station. PLANT, ETC. The contractor is to furnish all the plant, labor, material and machinery, except that which is herein specified as to be furnished by the Government, necessary for the complete and substantial execution of everything described, shown, or reasonably implied in the drawings and specifications. PROTECTION OF WORK, ETC. The contractor will cover and protect the work, material and machinery, and be responsible for all damage thereto until the final completion of the contract. He will clear away from time to time, as may be necessary, all dirt and rubbish resulting from the work, and on the final completion he will thoroughly clean all floors and windows, remove all debris, and leave the premises in good order. DRAWINGS AND SPECIFICATIONS. The drawings and specifications are intended to correspond and be illustrative of each other, and any work appearing in one and not in the other is to be done the same as though included in both. No advantage will be taken by the contractor of any omission of information in the specifications or drawings, as full explanations, or detailed drawings, will be given for any part of the work not sufficiently shown or understood. The contractor will substitute at his own cost and without delay, satisfactory work and material for any and" all that may be rejected, and will make good any work that may be disturbed thereby. SUPERVISION OF WORK. The authorized agents of the Light-House Engineer are to have access to the work and material at all times. Agents will be appointed to superintend the work in its various stages, and in case of a difference between one of these and the contractor, the decision of the Light-House Engineer shall be final. The agent appointed to superintend the construction of the work upon the concrete base shall be allowed the privilege of going to and from the work on such boats and by such means as the contractor may provide for transporting himself or his material and employees, whenever required, without expense to the Government. The contractor will furnish, without expense to the Government, such assistance in labor, tools and material, as may from time to time be required in marking lines and fixing points necessary in the progress of the work. The Light-House Engineer may, by written notice, require the contractor to dismiss at once such workmen or persons in his employ as he may deem incompetent, careless, or injurious to the work, and such individuals may not again be employed on the work. EXTRA WORK, ETC. The contract price is intended to include the cost of all things necessary to the station completed and in working order; but, should any extra work or changes be found necessary during the progress of the work, the value of such work or changes shall be the subject of a written agreement before being commenced, between the Light-House Engineer and the contractor, subject to the approval of the Light-House Board. All work of every kind and description must be done and completed to the satisfaction of the Light-House Engineer. DETAILED IDESCRIPTIOlSr. SHAPE OF PLAN, ETC. The outline of the plan of the concrete structure on which this tower is to rest will be formed by two segments of equal ellipses with corresponding axes at right angles to each other, placed so as to form a symmetrical figure, the distance between the centers of the two ellipses being 12 feet 6 inches, and the segments being joined by right lines tangent to both. The major and minor axes of the two ellipses being 25 feet and 21 feet respectively. The outline of the plan of the first story of the tower will be one foot inside of and parallel to this. The outlines of the plans of the second and third stories will be circular, having a diameter of 18 feet. The plan of the fourth story will 'also be circular in outline with a diameter of 13 feet 4 inches. The diameter of the lantern will be 8 feet 9 l / 2 inches. The general shape of the structure and the arrangement of its different parts are shown upon Plates II, III, IV and V, of the drawings which accompany these specifications, and which, with the specifications, are to form a part of the contract. Further details are shown upon succeeding plates, which will be referred to from time to time in these specifications. ACCESSIBILITY OF PARTS. In designing this tower the general idea has been kept in view that every part of it, both outside and inside, shall at all times be accessible for the purpose of easy examination and cleansing of rust. Compressed air being always available for sand blast purposes it will be an easy matter, even in this exposed position, to prevent deterioration of the iron work by thorough cleansing and painting. MATEEIAL. All the material which enters into the construction of this tower, except where otherwise stated or reasonably implied, will be of structural steel, shaped and put together as shown upon the drawings or herein specified. The material must be the best of its kind and suitable for the purpose. The workmanship must be.first class in every respect and in accordance with the latest practice. It is understood and agreed that the contractor is to make his own estimate of the material and work required, and to do everything in accordance with the drawings or specifications, or which may reasonably be required under them. Iron castings shall be of tough gray iron, cleaned and chipped and otherwise made finished pieces of work, in keeping with the careful work required in the steel construction. Bronze to be tough and of the usual U. S. Government standard. The steel used must meet the " Standard Specifications of the Association of American Steel Manufacturers " for medium steel. The tests must be done at the mill, and the mill certificate of tests will be accepted for the physical and chemical qualities, provided they meet the requirements of the above-mentioned standard. The contractor must, however, whenever called upon, furnish, without expense to the Government, prepared specimens of the several kinds of material as may be required by the Light-House Engineer, to fully determine their character. The edges of all plates which go to make up the outside walls must be parallel and at right angles, and these, together with the edges of all plates used in floors, roofs, etc., must be planed so as to fit the adjoining edge perfectly. The dimensions of rivets called for on the drawings shall be understood to mean the actual size of the cold rivet before heating. All rivets to be soft steel, standard chemical and physical properties. They shall fit neatly into the holes, fill the same completely, and form perfect heads when driven. All bolts used as permanent fittings in frames, walls or floors, to be turned to snug fit. All holes shall be accurately spaced so that when the parts are assembled rivets may be easily inserted, and may not exceed the diameter of the rivet by more than l-16th inch, and must not crack or bend metal on being 8 punched. Any corrections necessary shall be made with reamers. No drifting to enlarge unfair holes will be allowed. Riveted members shall have all parts well pinned up and drawn together with bolts before riveting is commenced. All slovenly-looking rivets shall be cut out and replaced. For permanent fittings all bolt holes in frames, walls, or floors, must be drilled to receive turned bolts in close fit. Other bolt holes may be punched. All screw threads must be tight fits in the nuts, and all threads shall be U. S. standard. All work possible, consistent with transportation and the assembling of parts, should be done in the shop, so as to reduce to a minimum the work to be done on the concrete base. ASSEMBLING OF PARTS, ETC. The tower shall be set up in the shops of the contractor, either as a whole or in stories, and suitably held together by bolts and temporary rivets, to insure the accurate fitting of the parts. After being inspected in this condition it shall be systematically marked so that the parts can be readily reassembled and prepared for transportation. All pins, nuts, bolts, and other small parts shall be boxed or crated so that they can be easily handled, and to insure against loss or damage. Should the inspector, through an oversight or otherwise, accept material or workmanship which is defective or contrary to the intent of the specifications, this material, no matter in what state of the completion of the work, may be rejected and the contractor required to replace it with other and satisfactory material. The surfaces of all parts that are to come together must first be thoroughly cleaned by wire brushes, sand blast, or other means, down to the gray metal, then given a heavy coat of red lead and boiled linseed oil. This requirement to apply to work done in the shop as well as that done in the field. No painting other than this just described will be required in the shop. CHANGE OF FORMS AND SIZES OF MATERIALS. Before submitting his proposal the contractor should satisfy himself that he can readily obtain structural steel of the shapes and weights required by these specifications. Should it so happen during the process of construction that the state of the market is such that some of the exact forms and sizes specified cannot be obtained within a reasonable time, then other shapes that can be obtained and which will answer the same purpose, may be substituted for these, upon written consent of the Light-House Engineer, and provided always that the substituted material be of the same strength as that which it replaces, or greater, and that there be no increase of cost to the Government on account of the sub- stitution. Always bearing in mind that the surface of the metal must all be accessible to the sand blast. DETAILS OF CONSTRUCTION. FRAME. The skeleton consists of four principal columns, numerous auxiliary posts, engine room and watch room walls, and angle studding in all walls, aligned, braced and secured at each floor with channel or angle caps or sills and numerous knee braces. COLUMNS. They are four in number, two extending unbroken from store room floor and two unbroken from engine room floor, to watch room floor. Below the kitchen floor the columns are composed of 8-inch I, 25% Ibs., reinforced by two channels 12 inches, 20y 2 Ibs., riveted thereto with %-inch rivets, 4 inches pitch for 2 feet at each end and 6 inches pitch for the balance.

'" / DATE: 190 NOTES. The surety's certificate of solvency must be signed by an officer of the Government known to the Department of Commerce and Labor. This form need not be used when a guaranty or surety company is upon the bond of a contractor. (42) Directions as to Execution of Contracts. 1. The contract papers proper, comprising the specifications, drawings, if any, contract, bond, bondsmen's oaths, justification by corporate surety when a guaranty or surety company is upon the bond of the contractor, instead of two individual sureties and certificate of solvency, should be made in quadruplicate, and each copy should be the exact counterpart of the others, so that any one of them may be used as an original. 2. Before signatures are appended to the papers, all dates should be written in, and all remaining blank spaces ruled out, with ink. 3. Interlineations and erasures are to be avoided when possible; but when they are unavoidable, either in the specifications, the contract, or the bond, they should be noted, word by word, immediately above the signature of the witnesses, specifying the number of each line where they occur; and certificates should be made that each specific correction or alteration was made before the contract was signed. 4. The full name and the residence of each signer of a contract and bond should be written in the body of the contract and bond. 5. When firms contract, the name of the firm and the full name of each member thereof should be written at the beginning of the contract; for instance, " Smith, Brown & Co., of the city of New York, a firm composed of John S. Smith, Charles B. Brown, and John W. Eobinson." The contract should be signed in the firm name without seal. The bondsmen must not sign the contract. 6. When an incorporated company enters into contract, the corporate name of the company should be written at the beginning of the contract and bond; for instance, " The Smith and Brown Dredging Company, a corporation created by and existing under the laws of the State of New York, of the city of New York, in said State." The contract and bond should then be signed with the corporate name by a person duly authorized to do so, sealed with the corporate seal, and a certificate, under the corporate seal of the company, showing the signer's authority to sign sealed instruments in its behalf, should be appended to one copy of the contract. In the event that the corporation has no corporate seal, a seal of wax or wafer should be affixed to the bond and adopted and used for the time being as the seal of the corporation, and the fact that such corporation has no corporate seal should be shown by affidavit duly made before a notary public, whose official seal should be affixed thereto. 7. A bond for the faithful performance of the contract will be required. Seals of wax or wafer should be affixed to the signatures of principals and sureties, if individuals; and corporate seals should be affixed as required by Rule G. The bond should bear the same date, or a date subsequent to that of the contract. 8. An individual or individuals, doing business under a firm name, should sign the bond in his, or their, individual names. Firm names should not be signed to the bond. 9. Each signature to a contract or bond should be made in the presence of at least one witness, who should sign his name as a witness. (43) 44 10. A firm will not be accepted as a surety, nor will a partner be accepted as a surety for a copartner, nor for a firm of which he is a member. An officer of a corporation will not be accepted as surety for such corporation. In no case will a married woman be accepted as a surety, and when an unmarried woman (widow or spinster) is given as a surety, she must be described as such in the body of the bond. 11. When a person signs a contract or bond as the agent or attorney in fact of another person, evidence of his authority to sign the same should be furnished. The authority to execute an instrument under seal should itself be under seal, and it should also be duly acknowledged before an officer empowered to take acknowledgments. 12. There must be not less than two individual sureties, but one corporate surety duly qualified under the Act of Congress of August 13, 1894, may be accepted as sole surety. The contractor and sureties should sign (execute) each bond. Each member of a firm should sign the bond personally or by attorney; in the latter case, a certified copy of the power of attorney under which the signature is made should be appended to the contract. Each surety must qualify in double the amount of the bond. This direction applies to corporate as well as individual sureties, and corporate sureties should also attach to each bond a copy of the last statement of their assets and liabilities, as rendered pursuant to Section 4 of the Act of Congress of August 13, 1894. Each surety should make and sign an affidavit of the amount he is worth over and above all debts and liabilities, and such exemptions as may be allowed by law. Sureties, other than corporate sureties, should state under oath that they are not responsible as sureties on any other bond, or, if so liable, the amount of such liability. When the required oath is taken before a justice of the peace, a certificate in the usual form should be appended, attesting his official character. This inconvenience can be avoided by having the oath taken before a notary public, in which case the notarial seal must be affixed or impressed. 13. A judge or clerk of a United States court, a United States district attorney, United States commissioner, postmaster, or a judge or clerk of a State court of record, with the seal of said court attached, should certify that the sureties are sufficient to pay the penalty of the bond, and except in the case of a judge of a United States court, or a United States attorney, if the person certifying has no seal, his official character should be duly certified. The foregoing does not apply to corporate sureties who have complied with Eule 12 of these directions relative to evidence of their ability to meet double the entire obligation of their bond. 14. Corporate sureties, duly qualified w do business, under the Act of Congress of August 13, 1894, and who have filed with the Solicitor of the Department of Commerce and Labor evidence of their authority to do business, from the Department of Justice, need not furnish a certificate of such authority with each contract on which they are bondsmen. 15. When contracts and bonds have been thus prepared, and signed and sealed by the officer making them, in behalf of the United States, they should be forwarded to the Board for approval. 16. When approved by the Board and by the Secretary of Commerce and Labor, two copies will be returned to the officer making the contract, one for delivery to the contractor and the other for file. \ RETURN TO MAIN CIRCULATION FORM NO.
