Tribune Extras Lecture and Letter Series. 



1872. Tha principal uses of photographs are for 

 the topographers m obtaining au idea of the 

 structural features, and for the geolosrist. Copies of 

 photographs taken were forsvardctl to the Vienna Expo- 

 sition, and some few have been printed for the use of 

 the War Department; but as yet no general distribution 

 h is baen made, although the views secured are 111 many 

 cases of peculiar interest. The series are of the land- 

 scape and stereoscope sizos ; the subjects are various 

 parts of Utah, Novadi, California, Ariz >na. and New- 

 Mexico. There is also a flue suite relating to the canons 

 of the Colorado, a selection of which, of the landscape 

 size, will lie brought before the public at au early day. 

 In his annual rcnotf to the Chief of E igineers Lieut. 

 Wheeler proposes to group the material at his disposal 

 into the following forms : 



1. Six quarto volumes. 



2. One topographic i! and one geosrnohical atlas. 19" bv 21". 



Vol. 1 is to include the general report concerning the expedition of 

 1ST 1 anil 1872, describing the country traversed, fac;s relating to its 

 industries tue eon'licion of presc-nt ami extinct aboriginal tribes, ic. 

 The text-matter will aggregate aliout 250 pages and 12 plates in illus- 

 tration. 



Vol. 2 will C'linpris" the sv>t>Miia' e report upon the lonsitu'le and lati- 

 tude eairp ligns "f 1*71 and 1872 in tbeir due order of bequeace, and, 

 if sulricien'.u ii"I:n I'll lirlore goiii" 1 to press, can receive in ad ition the 

 results fnuii ilu- ii"ld .MMSOH of l.S7ii, i"clu ling the establishment of the 

 obs'Tvatorv, ami the in ire matured pi in fur a comprehensive system of 

 astrono nical ileie-inin.nions in the area west of the one-hundredth 

 meridian. This volume will not exceed 250 pages, with but few addi- 

 tional plates. 



Vol. \i. This volume will ernhnce the collected data from a very Urge 

 nmnher of Imr.rly sta'ion.". and from meteorolo.'ic.-d record coiucetcd 

 with altitude work, illustrated by various tables and plates. The text- 

 matter will not exceed f>0 pages. The tables and plates will complete a 

 volume of moderate thickness. 



Vol. 4 will contain thj fi.nslied report of the geological work fir the 

 years 1871 and 1872. The sections will appear in Immediate con- 

 nection with the text. The size of this volume will not dilfer greatly 

 from '225 pages, increased br a few geological plateg. 



Vol. 5. Tnis volume, known to be the one upon " Palaeontology," 

 will contain a report anil num. Tons plates of the new vertebrate and 

 invertebrate tb-sils. for th vears 1871, 1872, and 187rf. The pages 

 of text matter will not exceed 100. and the plates for illust-ating new 

 sulijects probablr not more than 50 or GO. 



Vol. 6. This l^st voliim of the series will render the matured results. 

 for the years Is71, 1*7'J, and 1573, in the different branches of 

 natural historv, th ^ manuscript matter for which will call for at least 

 200 paces of quarto text and several plates. 



The following maps have already been published for 

 central distribution. In 18G9, map of South-eastern 

 Nevada, 1 inch to 12 miles; 1871, preliminary map, 1 inch 

 to 24 miles; 1872, preliminary map, 1 inch to 24 

 miles. Advanced copies of Atlas publication are 

 now ready. The finished work appears to be of the 

 best that has been executed in this country. Besides 

 tile preliminary sheets, there will be four full atlas 

 Sheets presented as photographed, in crayon and in 

 colors, accompanied by au index sheet and general topo- 

 graphical .-he.ets, progress m p, and a map allowing the 

 areas of dr linage, and the several basins of the territory 

 west of the Mississippi. Tins edition will be made as 

 large as the funds of the Survey will admit, but is not 

 expected to meet the constantly increasing demand for 

 trustworthy maps of tins section of the country. It is 

 intended to have oue topographical and one geological 

 atlas. 



The barometric profiles gathered by the observers 

 over the numerous routes of travel followed by the sur- 

 veying parties are numerous. The limited working 

 force of the office does not admit of their preparation 

 for publication at pr.'sent. 



LOSSES BV DEATH THK MUKDEtt OF LORIXG. 

 Considering tin: fact that the several expeditious num- 

 bering each year from 125 to'200 men. have traV'-rsed 

 these remote aud inhospitable regions, where want of 

 *vatcr, lieu?, d. in u'er from hostile Indians, etc., render 

 the tenure of life often precarious, it may be considered 

 remarkable that only six deaths have occurred, three of 

 which were caused by tho murderous hand of the 



Apache. In 1871, in the well-remembered stnge mas- 

 sacre near Hickenburg, three members of the expedition 

 of that year sold their lives dearly. One of them was 

 young Loring, a writer of rare ability and fomise ; 

 another, Mr. H;imell, chief topographer to the expedi- 

 tion ; the third, Mr. Severn, a prominent member 

 of the boat expedition of that year all serious losses to 

 the Survey. During this year two guides were lost in 

 the Death Valley region, and it is supposed that they 

 perished, no information to the contrary having as yet 

 been received ; at the time of their loss strenuous effort 

 was made to discover them, but without avail. lu 1872, in 

 Paria Creek. Utah, oue gentleman was drowned. Dur- 

 ing the past season Mr. William W. Maryatt, a most 

 prominent astronomical observer, died at Buzcman. 

 Montana. O:her accidents inevitable in a lift? of so 

 much toil, privation, and adventure, have occurred, but 

 no others were very serious. 



DETAILS OF ORGANIZATION. 



To secure an economical and yet thorough prosecution 

 of the work intrusted to his charge, it is proposed by 

 Lieut. Wheeler that the unit of forca in any given area 

 shall consist of three flild parties, with at le ist one offi- 

 cer in executive charge, one to b3 known as the triauicu- 

 latiou party, the others as parties for collecting topo- 

 graphical, meteorological, geological and other data. 

 These parties will carry ou their operations in lines 

 nearly parallel and make a thorough trigonometric con- 

 nection over the entire district surveyed. 



For the mam astronomical work there will be three 

 distinct parties ; one to occupy the central and connect- 

 ing station at Ogden, Utah, to be in charge of an engi- 

 neer officer; a second to occupy points accessible by 

 railroad communication within the area west of the 100th 

 meridian, and a third lightly equipped for duty away 

 from the railroad connections, yet at points wh TO; the 

 telegraph has penetrated. The parties so orgauizad 

 would consist of 



One officer, in charge. 



Officei-s in churgi' o' parties and as assistants. 



Three civilian astronomical assistants. 



Six civilian topographical assistants (including meteorological.obssrva- 

 tion). 



Four civilian geological assistants. 



One naturalist and three assistants. 



One photographer.
