SECTION OF ILLUSTRATIONS.

At the beginning of the war period the section of illustrations comprised 15 employees. By the transfer of three employees to the topographic branch for work on military maps and by resignations the force during the year was reduced to 10. As a consequence of this reduction the regular scheduled work has in general been delayed, but the aggregate number of drawings prepared was not less than in some previous years. The number of illustrations prepared was 2,522, comprising 197 miscellaneous maps, 188 photographs, 1,054 diagrams and sections, 943 paleontologic drawings, and 140 miscellaneous illustrations. The illustrations sent to the printer were reproduced by chromolithography, photolithography, halftone engraving, zinc etching, wax engraving, four-color process, and cuts already engraved, a total of 933 subjects. The number of proofs received was 952. At the end of the year material for illustrating 40 reports was on hand.

DIVISION OF DISTRIBUTION.

Editions of 147 new books and pamphlets, 12 reprinted books and pamphlets, 1 new geologic folio, 1 new geologic map, 181 new or revised topographic maps, and 179 reprinted topographic maps, making a total of 521 publications, were received during the year. Many other special pamphlets and forms prepared for administrative use were received and distributed.

The total units of all publications received numbered 558,604 books and pamphlets, 3,873 folios, 95 geologic maps, 945,293 topographic and other maps, a grand total of 1,507,865.

The division distributed 465,826 books, 8,865 folios, and 538,396 maps, a total of 1,013,087, of which 7,964 folios and 325,447 maps were sold. The total amount received and deposited in the Treasury as the result of sales of publications was $22,983.21. The sales of topographic and geologic maps amounted to $22,263.96, of geologic folios to $719.25. The division received and answered 69,897 letters.

DIVISION OF MAP EDITING.

SECTION OF GEOLOGIC MAPS.

Practically no editorial work on geologic folios was done during the year because of the discontinuance of the publication of folios during the war. Toward the end of the year, however, one folio that had been well advanced when work was discontinued was completed and published-Folio 208, Colchester-Macomb, Ill. The Newell (S. Dak.) and Herman-Morris (Minn.) folios were also nearly completed. The draftsmen of the section were employed during the large part of the year in preparing manuscript maps of the United States and of

foreign countries for an atlas of commercial geology. The base maps for Part I of the atlas, which deals with the production of minerals, were transferred to stone, and the geologic data were being prepared for reproduction in colors.

During the year G. W. Stose, the geologist in charge of the section, edited geologically the maps and other illustrations for 36 reports other than folios.

SECTION OF TOPOGRAPHIC MAPS.

At the beginning of the year 143 topographic maps were on hand for publication, and the accessions during the year were 118, making a total of 261 maps. Of these, 2 (Springdale and Maysville, Ohio) were combined in a single map, 180 have been published, 69 are in process of engraving and printing, and 10 have not yet been transmitted to the engraving division. One old map has also been republished in a new edition. Of the maps published (see notices on pp. 38-58), 142 are new maps engraved on copper, 30 are new maps reproduced by photolithography, and 8 (two of them photolithographs) are new combinations of maps otherwise published previously. The following statement shows the comparative status of map editing and map publication on June 30 for the last nine years:

Progress of map publication for nine years ended June 30, 1919.

The manuscripts edited during the year comprise 83 maps prepared for engraving, 30 maps for photolithography, 4 maps of Army cantonments, 169 maps or sheets for the illustration of 21 Survey reports, and corrections for 129 maps about to be reprinted. The proof read comprises 156 new topographic maps and corrections to 49 old maps. The index maps for 6 circulars of the series 9-323 and for 5 of the State circulars were revised and reprinted.

Four men were employed in this section for nine months and five men for three months.

Corrections were engraved on the plates of 126 maps. Of these maps 104 were intended for reprint editions, 1 was in hand for printing, and 21 were corrected for other purposes. Thirteen photolithographic State maps and 4 photolithographed topographic maps in four colors were corrected and reprinted, and reprint editions of 59 maps in hand at the beginning of the year were completed.

Of the new and reprinted maps 360 different editions, amounting to 945,293 copies, were printed and delivered to the map room. This is an increase of 61 editions and 241,955 copies over the preceding year.

One new geologic folio (Colchester-Macomb, Ill.) was published during the year. The edition of this folio was 3,873 copies. Extra geologic maps of this folio amounting to 140 copies were also delivered.
