It also summarizes the accomplishments of trade associations, individual businesses and the Government in the application of simplified practice. A detailed list is included, giving the simplified practice recommendations which have been effected in cooperation with American industries.

LIMITATION OF VARIETY RECOMMENDATIONS

LI. Elimination of Waste-Limitation of Variety Recommendation No. 1.-Paints and Varnishes.

During the war paint manufacturers, in cooperation with the War Industries Board, adopted a restricted list of colors, tints, shades of paint and varnishes, as well as of definite sized containers. However, immediately after the war a growing tendency to return to the former varieties was shown throughout the industry. The leading manufacturers were of the opinion that this war-time schedule should be maintained, and, after several conferences under the guidance of the division of simplified practice, it was unanimously approved at a joint conference of manufacturers, distributers, and users that the war-time schedule should be reaffirmed and considered as the recognized standard of practice for the industry for a period of one year effective September 1, 1924. This Limitation of Variety Recommendation No. 1 gives in detail the entire procedure and the list of preferred colors and containers. 8 pp. Price, 5 cents.

BUILDING AND HOUSING

BHI. Recommended Minimum Requirements for Small Dwelling Construction.

The report describes circumstances leading to appointment of Department of Commerce Building Code Committee; preliminary investigational work carried on by committee; details of measures for obtaining information on special questions; and cooperation extended by various interested organizations. It presents complete requirements for construction of small dwellings, in form suitable for adoption by States and cities. The requirements include sections on masonry walls of all types used in such structures; frame dwellings, with and without veneer of brick, stone, or stucco; wood framing in masonry structures; floor and roof loads; plastering; fire-stopping; and chimney construction.

A voluminous appendix is added to the report which explains reasons for many of the provisions recommended and gives much practical information on building materials and methods and also includes numerous illustrations of approved building practice. (July 20, 1922.) 108 pp. Price, 15 cents.

BH2. Recommended Minimum Requirements for Plumbing in Dwellings and Similar Buildings.

The justice and particularly the scientific bases of plumbing regulations have been much questioned. The committee of experienced sanitary engineers, appointed by Secretary Hoover, supervised extensive investigations at the bureau to settle these disputed problems.

Their report described variations in present plumbing practice as influenced by State and city codes; presents a recommended plumbing code for dwellings and similar buildings for use of those writing or revising plumbing codes; discusses many of the mooted points in plumbing regulation, and includes a detailed report of extensive test series with domestic plumbing equipment, carried on at the Bureau of Standards.

The recommended plumbing code is based on the results of the experimental work described and permits important modifications of present code requirements leading to considerable economies in the design of plumbing systems. (July 3, 1923.) 260 pp. Price, 35 cents.

BH3. A Zoning Primer.

The object of a Zoning Primer is to give a readable presentation of the subject in brief compass. It defines zoning and explains the need for dividing growing cities and towns into districts in which the use to which buildings may be put, their height, and the area of the lot which they may cover are regulated. It tells how zoning protects property and health and reduces the cost of living. It explains that zoning is legal, and how to get a zoning program started, and concludes with a statement of what a number of cities and towns have accomplished by zoning. 7 pp. Price, 5 cents. BH4. How to Own Your Home: A Handbook for Prospective Home Owners.

This pamphlet is designed as a handbook for prospective home owners. After a discussion of some general factors, such as the arrangement of safe expenditure, and the percentage of income to devote to payments, it takes up the importance of having agreements in regard to financing, building, and purchasing, properly signed by both parties and drawn with careful attention to legal details. Various methods of financing and the principal types of institutions that lend to home seekers are described. Considerations governing the choice of a lot, house plans and quality of construction, the question of buying or building, the procedure and precautions to be taken when either course is chosen, and maintenance costs and expenses of home ownership are treated separately. An appendix contains financing tables and examples of typical financing transactions. 28 pp. Price, 5 cents.

BH5. A Standard State Zoning Enabling Act.

This act was drafted to meet the needs of States wishing to adopt legislation permitting municipalities to adopt zoning regulations. Since it was first issued in mimeograph form in August, 1922, at least 15 States have passed zoning enabling acts modeled either wholly or partly after it. Before the act was issued, existing State acts and court decisions with reference to zoning as it has been practiced and found successful in cities and towns throughout the country, were carefully studied. The act is accompanied by ample notes which explain the desirability of having a carefully prepared act and which give the reasons for the substance and phraseology of many of the provisions. The eight sections of the act deal with the following subjects: Grant of power, districts, purposes in view, method of procedure, changes, zoning commission, board of adjustment, and remedies. 12 pp. Price, 5 cents.

BH6. Recommended Minimum Requirements for Masonry Wall Construction.

The third report of the Department of Commerce Building Code Committee presents a model code for regulation of masonry, including walls of brick, tile, concrete units, stone, and plain concrete. The introduction describes variations and inconsistencies in present code requirements and the methods utilized by the committee in drafting the recommended code. Careful investigations were made of data obtained by tests of masonry materials and walls, and successful experience in many localities was consulted. This information is given in an appendix to the report, together with such other material of interest to builders. (June 26, 1924.) 57 pp. Price, 15 cents.

BH7. Minimum Live Loads Allowable for Use in Design of Buildings.

The fourth report of the Department of Commerce Building Code Committee presents live-load requirements recommended for general adoption by States and municipalities with the object of preserving safety, stimulating uniformity of requirements, and conserving materials and labor. The introduction describes variations and inconsistencies in present code requirements and cites investigations made. A great deal of test data, actual live-load measurements and observations were obtained from those who have studied the subject. This information is given in an appendix to the report, together with much other interesting material. (Nov. 1, 1924.) 38 pp. Price, 10 cents.
