time to teaching, the remainder, either at home or abroad, to 

 the further prosecution of his research. A year and a half of 

 great productiveness followed. He bought a small tract of land 

 adjacent to the college campus, built a residence upon it and 

 planned to devote the remainder of his days to breeding animals 

 on an extensive scale and studying tne laws of heredity, com- 

 parative psychology and allied problems. But before this pro- 

 ject was fully under way his health broke down completely and 

 he was forced to abandon his home in the fight for life. 



In December, 1893, he had a severe attack of la grippe, 

 but, as was his custom in illness, went on with his work as 

 usual. Upon completion of the last examination of the term 

 he came home too ill to correct the papers, and in course of 

 the following night was attacked by a severe hemorrhage from 

 the lungs and for weeks his life hung in the balance. With 

 the return of spring his strength increased sufficiently to enable 

 him to remove to New Mexico, where the local physicans told 

 him that he had a fighting chance for a {qw years. He accept- 

 ed the challenge bravely and for more than ten years held the 

 disease in check. During the spring of 1894 his college dedi- 

 cated the Barney Science Hall, which had been built largely un- 

 der the stimulus of his presence in the faculty; but he was never 

 permitted to work in it. 



The fourth period, from 1894 to 1904, covers the remain- 

 ing years of his life. 



This decade, filled with bodily pain and the worse torture 

 of anxiety and mental unrest, is yet one of the most productive 

 periods of his life. Much of the time was spent in the open 

 with covered wagon and camp kit, and with the return of 

 strength scientific interests again absorbed his attention. Nat- 

 urally in this case he again turned to geology and an extensive 

 series of articles on the geology of New Mexico bears testi- 

 mony to the industry of these apparently aimless wanderings. 

 The first scientific work done in the Territory, however, was a 

 revision of his earliest important work, the Crustacea of Minne- 

 sota. As soon as his geological knowledge became known his 

 services were in demand as a mining expert and during the later
