124 Patmer, In Memoriam: Wells W. Cooke. Fess 
From Burlington, Cooke went directly to Fort Collins, Colo., 
where in the autumn of 1893 he took up the duties of Agriculturist 
at the State Experiment Station. He remained in this position 
for seven years busy with the varied duties connected with teaching 
agriculture and attending farmers institutes, but not unmindful 
of the birds. His experiment station work dealt with problems 
of forage crops, stock feeding, sugar beets, and dairying. Of the 
13 bulletins which bear his name he was sole author of 9 and co- 
author of 4; four of these publications relate to stock feeding and 
three each to sugar beets, miscellaneous farm notes, and birds. 
Conditions at Fort Collins were evidently much more favorable for 
bird study than at Burlington and the incentive of a new fauna, 
diversity due to influence of altitude on bird life, and the oppor- 
tunity for observation during his thousands of miles of travel every 
year in the course of his station work bore rich fruit later in his 
‘Birds of Colorado.’ A few months after his arrival his first paper 
appeared and during his residence in the State he published 10 
articles on birds in addition to three bulletins on the ‘Birds of 
Colorado.’ Two incidents of his Colorado experience also merit 
mention — a visit to Salt Lake City the most western point he ever 
reached and a severe attack of typhoid fever in October, 1895, from 
which he did not fully recover for nearly a year. 
At the beginning of the autumn term of 1900 Professor Cooke 
became connected with the Pennsylvania State College in the 
capacity of volunteer associate engaged in research work in animal 
nutrition. The results of this work appeared in a paper on ‘The 
Maintenance Ration of Sheep.’ This report was finished in the 
spring of 1901 and is interesting as the first publication signed 
“Wells W. Cooke.’ All his previous papers appeared under the 
name ‘W. W. Cooke,’ and the change he afterwards explained was 
made at the beginning of the new century and was consistently 
maintained, except in his migration papers in ‘ Bird-Lore.’ Thus, 
even without dates, it is easy to distinguish his 19th century from 
his 20th century contributions. 
On July 1, 1901, Professor Cooke received an appointment in 
the Biological Survey in the U. S. Department of Agriculture and 
the remaining 15 years of his life were devoted to work on bird 
migration and distribution. As Dr. Chapman has well said,
