acre tract of land belonging to his sister, a commodious one room 
cabin was built with a cheerful open fire place and a comfortable 
porch, where with his sister and daughter he entertained informally 
but with unusual hospitality several hundred of their friends a few 
at a time in congenial groups. Here he brought together a collec- 
tion of living ferns of the District practically complete so far as 
local species were concerned, and here and on an adjoining farm he 
made his first bird census in 1911. The Wickiup will long be 
remembered not only by those who have seen it, but also because 
of its association with certain phases of his ornithological work. 
In ‘Bird House Tenants’! he has described his failure to induce 
Purple Martins to take up their abode in the house erected for 
their special benefit, and in the bird census reports ” he refers to his 
first experiments at this place where the ideas were gained which 
later were embodied in the instructions sent to observers who 
codperated in the first general census. 
Cooke was an indefatigable worker and his interests extended into 
several distinct fields. The list of his ornithological contributions 
prepared by himself includes about 200 titles, but no list is available 
of his many publications on the branches of agriculture to which 
he devoted attention. It is impossible at this time to give a bib- 
liography of his publications on birds or to attempt more than a 
brief reference to some of the more important papers. His first 
article appeared in 1881,’ and his last in 1916,* within a day or two 
of his death. During the 35 years of active work his chief contribu- 
tions were made to the subjects of distribution, bibliography, and 
migration. 
In distribution his most important contributions are Part 2 of 
the bulletin on ‘Bird Migration in the Mississippi Valley’ and his 
‘Birds of Colorado’ with three supplements,’ bringing the informa-
