The work of mapping the United States has been intrusted by Con- gress to the United States Geological Survey, which is to prepare a topographic map or atlas of the entire country and is now and has been since its establishment in 1578 engaged continnously on this work. So far it has surveyecl about 1.,200,000 square miles, exclusive of areas snrveyed in Alaska and Hawaii, or about two-fifths of the United States. The sheets or maps forming this atlas represent areas that are called quadrangles, whose bounclaries are lneridians of longitude and parallels of latitude. About 2225 quadrangles have now been mapped. The sheets of paper on which these maps are printed are of nearly the same size (abdut 17 by 20 inches) and the maps are alike in 4 general character, but the size of the maps differs with difference in the latitude of areas mapped, and the areas represented on different maps differ in size according to the scale used. Most of the maps are pub- ?L lished on one of tlhree scales, about 1mile to the inch (1 :62,500), a about 2 miles to the inch (1:125,000), or about 4 miles to the inch w (1:250,000), ancl cover, respectively, a,verage areas of about 230, V, 920, and 3700 square miles. The largest scale, showing the most detail and representing the smallest area, is used for densely popu- lated or otherwise important areas ; the next largest for scantily inhabited mountainous or desert regions; the si~~allestfor areas covere(1 by reconnaissance surveys, especially in the JJTestern States aud Alaslta. For some areas of particular importance special large- scale maps are publishetl. . The maps show the topographic features of the land, snch as moun- tains, hills, valleys, and gulches; all bodies of water, such as lakes, marshes, streams, ancl springs ; the routes of travel, such as railroads, wagon roads, and trails ; political boundaries ; cities, toens, and permanent buildings ; and the names of natural and other features. They also indicate exactly the location of permanent surrey nlonu- ments and bench marks whose positions and whose elevations above sea lerel have been determined by precise methods-nlonlinlents that are nvail:tble as starting points for local snrveys. The maps of areas covered hy public-land surveys show all township ancl section lines as well as the boundaries of all land grants. 3 4 UNITED 'STATES (fEOLOGICAL SURVEY MAPS AND FOLIOS.

ICach of these maps is printed in three colors-black for the cultnral features, such as boundary liues, roads, railroads, houses, towns, and cities, and for the names of all things represented; brown for the hypsography, or the element of elevation, indicated by contour lines sho~vingthe heights of all parts of the area above sea level; and blue for the water-the rivers, the lakes, and the sea and its bays and inlets. Each quadrangle is named from some prominent natural or other feature within it-such as a lake, mouutain, tonrn, or city-and the map should be orclered by that name. Index maps showing the loca- tion ancl the names of quadrangles mapped in any State or region will be furnished on app1ic:ttion. (See list on pp. 5 and 6.) These maps are sold by the Geological Survey at the cost of publi- cation. The price of the LLstandard77maps is 10 cents each, or $6 a hundred. The prices of other maps are given in the following lists. A discount of 40 per cent is rnacle on orders for topographic maps (either of oue kind or any assortment) amounting at the retail prices to $5 or more. * NATUREOF THE GEOLOGI~ FOLIOS. As the topographic atlas of 'the United States mill consist of Inany separate sheets, each showing the topography of a qnadrangle, so the geologic atlas of the United States mill consist of many separate folios, or bound groups of sheets, each folio showing the geolo,oy of one or more cpadrangles. Zach folio includes a descriptive test, a topographic map, and one or more geologic ruaps, with columnar or cross sections and such other illustrations as may be required to show clearly the geologic featnres of the region mapped. The topographic map of the quad- wngle forl~lsthe base for the geologic map, and the scale and the general features of both are the same. The test of each folio contains an outline of the geography of the region ; a sketch of the topography ; a full description of the geology, showing the character, origin, and age of the rarious rocks ; a sum- mary of the geologic history of the area; and an account of the availrtble rnineral resources, including water resources, surface and und erground. The folios are sold at about the cost of paper, printing, and binding. Some of the later folios are printed in t\l7o editions-a library and an oct$ro or field edition. Owing to a fire in the Geological Survey building May lS, 1913, the stock of geologic folios mas more or less damaged by fire and water, but SO or 90 per cent of the folios are They will be sold at the uniform price of 5 cents each, with no for wholesale orders. This rate applies to folios in stock UNITED STATES GEOLOGICAL SURVEY NAPS AND FOLIOS. 5 from 1 to 184 inclusive, also to the library edition of folio 1%. The library edition of folios 185,187, and higher numbers sells for 25 cents a copy, except that some folios which contain an unusually large amount of matter sell at higher prices. The octavo edition of folio 185 and higher numbers sells for 50 cents a copy, except folio 103, the price of which is 75 cents. If 34 folios selling at 25 cents each (or their equivalent in higher-priced folios) are ordered at oue time a discolmt of 40 per cent is allowed;' $6.10 is the minimum amount accepted at this rate. Separate geologic maps from some folios, especially from folio 164 and later folios, have been printed suct are sold for 5 cents each. INSTRUCTIONSFOR ORDERING. Prepayment is required, and may be made by money order, payable to the order of the Director of the United States Geological Survey, or in cash-the exact amount. Naps shoulci be ordereci by name (iucluding State name); folios should be .ordered by number. If one or two maps included in tt large order are not in stock it is the practice to substitute others rather than to return very small sums of money by mail, unless directions to the contrary are given in the order. Name of cot~ntyshoz~ld be incltided in post-ofice address.

A set of index circulars j7 has been prepared, showing the maps and folios completed for different regions of the country and the stages of the work iu areas for which maps or folios are in preparation. These circulars are revised at short intervals and contain, in itddition to full information concerning t'he maps, the names of agents who have for sale the maps of areas in each region. The following is a list of these index circulars : 9-323a. New England. 9-323b. New York, ?Sew Jersey, Pennsylvania, Delaware, and Dfaryland. 9-32%. Blaryland, Virginia, and West Virginia. .. 9-323d.

A general circular (0-323) in regard to the geologic folios is also pnblished by the Surrey. Auy of the circulars mentioned above mill be sent free on application. The Survey has issued a sheet of "Lettering and collventional signs 77 used on. its topographic maps, price 1.0 cents a single sheet, 6 cents in lots of 50 or more ; also a sheet of LC Convent,ional signs," showing symbols and ~~bbreriationsadopted by the United States Geogrttphic Board, price 20 cents a copy or 12 cents when included in wholesale orders.
