254 ANNUAL RECOED OF SCIENCE AND INDUSTRY. 



The several branches of the Survey were accompanied by- 

 geologists and naturalists, as follows : G. K. Gilbert, chief 

 geologist; Professor J. J. Stevenson, geologist; E. E. Howell, 

 assistant geologist; and Dr. Oscar Loew, mineralogist and 

 collector. The naturalists were Dr. J. T. Rothrock, acting 

 assistant surgeon, Dr. C. G. Newberry, H.W. Henshaw, John 

 Wolf, and John M. Keasby ; T. H. O'SuUivan, photographer; 

 and A. A. Wyant, artist. 



Other persons who rendered more or less service during 

 the survey are Mr. Francis Klett, G. M. Lockwood, and Will- 

 iam D. Wheeler. 



It is proper to state that Lieutenant Wheeler has kept up 

 a full working corps in the office at Washington, for the pur- 

 pose of completing the maps and reducing the observations 

 made during the previous season ; and it is proposed to in- 

 crease this to an extent sufficient to keep pace with' the prog- 

 ress of the survey, year by year. The area traversed by 

 the various parties during the season is estimated at about 

 50,000 square miles. 



In addition to reports to Congress of current operations, 

 Lieutenant Wheeler proposes to publish the final results of 

 the survey in six quarto volumes, with the necessary illustra- 

 tions, and two atlases of maps. The first of these will be a 

 general volume; the second, an astronomical; the third, a 

 meteorological ; the fourth, a geological ; the fifth, a paleon- 

 tological ; and the sixth, a natural-history volume. Of these 

 volumes, one, two, and four are promised at an early date ; as 

 also a certain number of the finished sheets of the toj)- 

 graphical atlas. 



EXPLORATIONS OF CAPTAIN WILLIAM A. JONES. 



The expedition under Captain William A. Jones, which

The party, accompanied by Dr. C. C. Parry, as botanist 

 and meteorologist, and Professor Theodore B. Comstock, ge-

 to Camp Stambaugh ; thence northwest along the base of
