LETTER OF SUBMITTAL
DEPARTMENT OF COMMERCE,
Washington, November 5, 1929. Sir: I have the honor to submit herewith for publication the fourth issue of the Standards Yearbook.
In the earlier issues of this publication special attention was paid to the organization and procedure of the numerous standardizing agencies in this country with brief outlines of certain national and international agencies. The present volume contains outlines of the activities and accomplishments of not only the National Bureau of Standards and other agencies of the Federal Government and the States, counties, and municipalities, but also those of technical societies and trade associations, with special emphasis on their accomplishments during the year 1929, their programs for future work, and the methods employed by each organization to encourage or facilitate the use of its standards and specifications.
Among the special features of the present yearbook is an outline of the important and significant standardization activities and accomplishments in transportation. There are also featured certain developments in the attempt to simplify the calendar, an article on this subject having been contributed by Charles F. Marvin, Chief of the United States Weather Bureau. Included also is a bibliography of recent publications relating to standardization contributed by courtesy of William Adams Slade, chief, division of bibliography, Library of Congress.
The Standards Yearbook is proving of much value to manufacturers, industrial experts, and engineers, as well as to purchasing agencies both governmental and general. Respectfully,
GEORGE K. BURGESS,
Director Bureau of Standards. Hon. R. P. LAMONT,
Secretary of Commerce.
