said District of Columbia is hereby limited and restricted to eight hours in any one calendar day, and it shall be unlawful for any officer of the United States Government or of the District of Columbia, or any such contractor or subcontractor whose duty it shall be to employ, direct, or control the services of such laborers or mechanics, to require or permit any such laborer or mechanic to work more than eight hours in any calendar day except in case of extraordinary emergency." (N. R. 1573-1, citing act of Aug. 1, 1892. See par. 27-142 herein.)

17–13. Overtime work in emergency. "Under the provisions of law set forth in the preceding paragraph, the working hours of laborers and mechanics at navy yards and naval stations can be extended over eight hours a day only in the case of an extraordinary emergency." (N. R. 1573-2). The following pertinent extracts are quoted from Navy Department circular letter SONYD-7-GR, dated July 24, 1923:

Hereafter the eight hour law of March 3, 1913, will be strictly complied with and no laborer or mechanic will be required or permittd to work more than eight hours in any one calendar day except in case of extraordinary emergency which has been construed by the Attorney General in two circulars as follows:

"Attention is called to the fact that the emergency provision in the law is considered to cover any extraordinary emergencies which can not be foreseen, such as might be necessary for saving life or property of the United States, and not cases which depend for their emergency solely upon economical methods of work or importance of rapid construction."

"An 'extraordinary emergency' under the act is one not to be foreseen in time to avoid the necessity of exceeding the limit of the fixed daily hours of labor by the employment of more men or more shifts of men. Mere economical considerations do not affect the question at all. It is assumed that in making the requirement Congress knew that under many conditions the law would impose great expense upon the Government." For administrative reasons, it is further directed that no civil employee, regardless of title or group classification, shall be permitted to work in excess of eight hours in any one calendar day, except in case of extraordinary emergency, as construed herein, without the specific authority of the department.

17-14. Commandants may authorize overtime work. "In cases of emergency involving loss to the Government which will not permit of delay, the commandants of navy yards and stations may authorize, without the prior approval of the department, work in excess of eight hours a day and work on Sundays and holidays not to exceed eight hours a day, provided that, in each case where overtime work is authorized, due consideration shall be given to the provisions of the two preceding paragraphs." (N. R. 1573–3.)

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
