" In 1869 we removed to Wilkes-Barre, Penn- 

 sylvania, where I was fortunate in working up 

 a good practice. It has always been a pleasant 

 thought that I was enabled to take an active part 

 in starting the Wilkes-Barre Hospital on a long 

 career of usefulness as one of the leading hos- 

 pitals of the state. 



" In the spring of 1873 my health gave way 

 so completely that I was obliged to abandon 

 medical practice. A position as Botanist and 

 Surgeon to the Surveys West of the looth Me- 

 ridian, under the direction of Lieut. George M. 

 Wheeler, U. S. Engineer, was offered and gladly 

 accepted. I was assigned to duty in Colorado 

 under Lieut. William M. Marshall. There was 

 little medical duty, but Prof. John Wolf and 

 I together managed to collect about ten sets of 

 plants, which would average one thousand spe- 

 cies each. I must say, however, that Professor 

 Wolf deserves more credit for this than I do, as 

 much of my time was taken up with general ex- 

 ecutive work. I did, however, manage to place 

 the barometer on the top of a large number of 

 the highest peaks in central and southern Colo- 

 rado and obtain readings there.
