17-15. Restriction in withdrawing materials from stock. "The quantity of materials drawn from store at a navy yard for work to be performed therein shall be restricted in every instance to that which is actually needed for the job concerned. When a job is likely to extend through a period of time including the end of a fiscal year, only material actually to be consumed upon the specific job before the end of such fiscal year shall be drawn, if possible; otherwise any surplus shall be invoiced back into store before the expiration of the fiscal year. Any material remaining on hand upon the completion of the job for which drawn shall be turned into store immediately on return material credit memorandum; and under no circumstances shall materials remaining on hand after the completion of the jobs for which drawn be permitted to accumulate." (N. R. 1593.)

17-16. Extending availability of appropriations in case of work performed by Government-owned establishments. In paragraph 8-50 herein (Ch. 8) will be found instructions relative to the procedure for extending availability of annual appropriations beyond the end of the fiscal year for which made, in cases where work is performed at Government-owned establishments.

17-17. Monthly progress reports and photographs; final reports. On all jobs performed under special allotments, the bureau requires the submission of a monthly progress report on Y&D form 87. All spaces on the form should be filled out. If for any reason it is not possible to name even an approximate date for completion, a brief statement of the reason should be made under "Remarks." In general, yard labor work, as well as contract work, should be planned with a definite schedule of progress. For description of this form and further instructions, see Chapter 6 herein. Upon completion of the work, a final report is required, also on form 87, showing the total cost and a comparison with the amount of the bureau's allotment. For disposition of the unexpended balance, see paragraph 8-62 (Ch. 8) herein. Monthly progress photographs are also required on all construction and major repair projects; detailed instructions relative to the submission of photographs will be found in Chapter 14.

17-18. Desirability of technical reports on day-labor jobs for publication. A principal end to be served by the publication of the bureau's quarterly bulletin, Public Works of the Navy, is to

enable officers in charge of construction at the several stations to share with their colleagues studies made and experience gained in the execution of projects, whether performed by contract or by day labor. The latter class of work offers a very significant field for contributions to the bulletin, in that every detail of the job, from beginning to end, is under the direction and control of the officer on the site. Technical reports covering such construction are therefore invited, in any cases where the work may have developed features of engineering interest from the standpoints of design, difficulties overcome, economies effected in construction, and the like. Reports prepared especially for bulletin publication should be submitted direct to the chief of bureau, accompanied by an appropriate letter of transmittal, and should be typed with lines double-spaced. An appropriate selection of photographs and tracings for illustrative purposes will always add to the interest of the article. A suggested general outline for such an article is the following: Necessity for the work; design; construction, including plant, methods, conditions, time, etc.; costs.

SUPPLIES AND MATERIALS.

Requisitions; Used Material; Transfers to or from Other Bureaus or Government Departments.

REQUISITIONS.

18-01. Purchases; relations with Bureau of Supplies and Accounts. Supplies and materials for the construction and maintenance of public works and public utilities are purchased under the authority and provisions of appropriations made by Congress. General instructions relating to purchases are set forth in articles 18461850, inclusive, of Navy Regulations. The following articles are also cited: "All purchases and payments therefor shall be made under the direction of the Bureau of Supplies and Accounts, and orders directing such purchases and payments shall be given only by that bureau. When open-purchase requisitions have been approved by chiefs of bureau, they shall be transmitted to the Bureau of Supplies and Accounts for action." (N.R.1604.) "** *requisitions * intended to cover purchase of supplies or material needed for immediate use or for a specific purpose shall be submitted to the Bureau of Supplies and Accounts through the bureaus concerned. If, in the opinion of the former bureau, any such requisition should not be approved, then the Bureau of Supplies and Accounts shall so inform the bureau concerned. In the event of failure of the two bureaus to reach an agreement the questions at issue shall be referred to the Secretary of the Navy."

(N. R. 1607-3-b.)

18-02. Materials procurable on requisition. Supplies and materials are procurable only on requisitions approved by competent authority. Where supplies and materials required are carried in naval supply account fund stock, they are procurable on stub requisitions; where the materials required are not so carried, they are procurable only on purchase requisitions, S. & A. Form 76-1, except where a semiannual, annual, or other continuing contract has been made. At the present time it is the practice to make semiannual contracts for furniture, rugs, and carpets for officers' quarters, and

such contracts provide that orders thereunder shall be placed by the Bureau of Yards and Docks. When it is desired to procure any material under such contracts, request should be made in letter form addressed to this bureau, reference being made to the item number of the contract, and such other information given as is necessary to enable the bureau to place the order. In cases, however, where the purchase is to be made under an appropriation other than that specified in the contract, a requisition, S. & A. Form 76-1, should be submitted in the usual manner in order that the proper obligation may be set up against the appropriation involved. The order under such requisition will be placed by the bureau under the contract, in the same manner as orders based upon request by letter, the requisition being required for bookkeeping purposes only.

18-03. Services procurable upon requisition. Except in cases where public works contracts are executed by the bureau, services (other than by Government employees) necessary for the maintenance of public works and utilities are procurable only on requisitions on S. & A. Form 76-1, approved by competent authority.

18-04. Utilization of stock material where possible. "Commandants, heads of departments, and surveying officers are * * * directed to cooperate in utilizing such [stock] material wherever practicable. Yard requisitions for material for special purposes or material for installation in particular places shall carry in the future a certificate by the head of the department concerned that the stock on hand of a similar character or of the approximate size has been examined, and that none of it will answer. If it be considered that stock on hand of the same character or size can not be economically used the particulars shall be communicated to the bureau concerned for its decision as to the best course to pursue. Consideration should be given to substituting stock on hand for standard material whenever practicable." (G. O. No. 3, January 5, 1921.)

18-05. Origin of requisitions. "For all supplies needed that are not obtainable under existing contracts, with the exception of those pertaining to the Bureau of Medicine and Surgery and to the Marine Corps, and of those which may be purchased upon the requisition of a chief of bureau approved by the Bureau of Supplies and Accounts, requisitions shall be prepared by the technical officer concerned, and submitted by a supply officer, with four memorandum copies, numbered in separate series for each bureau and beginning

a new series for each fiscal year." (N. R. 1607-1.) "The heads of departments and divisions shall make request upon the supply officer for supplies and material as required and shall keep him advised in advance as to the probable needs of their several departments and divisions. An officer making a requisition shall be responsible for the necessity for the article for the purpose stated; the necessity for the delivery within the time specified; the estimate of cost; the statement as to the appropriation against which the charges are to be made; and the specifications describing the different items." (N. R. 1524.)

18-06. Requisition forms (ashore). "All requisitions on the supply officer for materials or articles for use in any department or division shall be made in the form prescribed by the Bureau of Supplies and Accounts." (N. R. 1525.) As prescribed by that bureau, S. & A. Form 76-1 (original) will be used for all requisitions ashore where purchase is involved. The original (white) will be submitted with four green copies (on Form 76a) and one yellow copy (on Form 76b). Additional copies should be made as required for the station's files.

18-07. Preparation of requisitions. Requisitions submitted under Bureau of Yards and Docks appropriations, or for materials or services ultimately chargeable to such appropriations, must comply with all the requirements of Navy Regulations (arts. 1607, 1609, and 1610); detailed instructions, in which the requirements of the Navy Regulations have been incorporated, will be found in paragraphs 390 to 406, and 430 to 470, inclusive, of the Manual for Supply Officers. Especial attention is directed to the following information in which this bureau is particularly interested, inclusion of which will be necessary to secure the bureau's approval of any requisition:

1. The number of the allotment against which the obligation is to be incurred. 2. The appropriation chargeable.

3. Definite descriptive specifications.

4. Proprietary certificate on requisitions for proprietary articles.

5. Letter of explanation in cases of unusual requisitions.

6. Definite statement of purpose for which material is required. Requisitions for equipment should indicate whether the articles called for are to replace similar articles formerly in use, and in such cases should refer to the survey report showing disposition of the article to be replaced; if the article is in addition to the equipment on hand the necessity therefor should be stated, either in the requisition or by accompanying letter.
