increased. In the fiscal year 1896-97 returns from sales of topographic maps amounted to $505.77; in the year 1902-3 the sum was $7,071.50. Over 1,300 maps are now carried in stock. The maps are stored according to geographic sections, so as to facilitate the filling of orders. Many of the orders are vague and uncertain, and frequent recourse must be made to gazetteers, guides, and other reference books to locate the regions for which maps are wanted. At the beginning a card-index system of record was devised. On the cards are recorded, as required by law, the addresses of those to whom documents have been sent, what documents were sent, dates of sending, etc. To facilitate the distribution of the topographic maps, and for the convenience of the public, the Survey has appointed agents in the different States. These now number 76. The agents agree to carry in stock maps of areas in their immediate vicinity. This enables persons who have need of maps to make personal examination of them before purchasing, and to procure copies at once, avoiding the delay incident to correspondence. To give adequate publicity regarding the documents and maps issued by the Survey, card notices and circulars were formerly prepared and mailed to correspondents, scientists, and others interested, the mailing occupying a considerable portion of the time of one clerk. It was soon learned, however, that the press of the country would be glad to print news items and short notices of publications, and since 1902 the Survey has prepared and issued weekly a press bulletin. The work connected therewith was assigned to the document division, and an editorial clerk was appointed to prepare the news notes and review notices. Prior to June 30, 1903, nearly 4,000,000 copies of publications, folios, and maps were distributed by the document division. Of that number 2,716,652 were distributed during the last five years, while in the five years prior the number was 966,875, a total of 3,683,527 for ten years, or 92 per cent of the entire distribution during the twenty-five years the Survey has been in existence. During the fiscal years 1899-1903, a period of four years, 346,119 letters were mailed by the document division, this being over 50 per cent of the entire number sent prior thereto. These statements attest the growing public interest in the work of and the results achieved by the Survey. PUBLICATIONS OF THE UNITED STATES GEOLOGICAL SURVEY. Following are complete lists, to date, of the serial publications of the United States Geological Survey, which consist of (1) Annual Reports, (2) Monographs, (3) Professional Papers, (4) Bulletins, (5) Mineral Resources, (6) Water-Supply and Irrigation Papers, (7) Topographic Atlas of United States-folios and separate sheets thereof, (8) Geologic Atlas of United States-folios thereof. The Bulletins, Professional Papers, and Water-Supply Papers treat of a variety of subjects, and the total number issued is large. They have therefore been classified into the following series: A, Economic geology; B, Descriptive geology; C, Systematic geology and paleontology; D, Petrography and mineralogy; E, Chemistry and physics; F, Geography; G, Miscellaneous; H, Forestry; I, Irrigation; J, Water storage; K, Pumping water; L, Quality of water; M, General hydrographic investigations; N, Water power; O, Underground waters; P, Hydrographic progress reports. A table showing the papers of each series is given on pages 148 and 149. The classes numbered 2, 7, and 8 are sold at cost of publication; the others are distributed free. It is impossible to comply with general demands for the publications which are distributed free, such as to have all of any series sent, but requests for a certain paper are granted whenever practicable. No person will be given more than one copy of any publication. Many of the publications of the Survey are out of print, but these can usually be obtained from dealers in secondhand books in any large city. For publications to which prices are affixed prepayment is required, and should be made in cash (exact amount) or by postal or express money order payable to the Director of the United States Geological Survey. Checks, stamps, or foreign coin can not be accepted. Full address, including county, should be given. Address all communications to THE DIRECTOR, U. S. GEOLOGICAL SURVEY, WASHINGTON, D.
