I. AN IMPROVED TRAP-NEST. 



Invented by R. C. La wry. 



During the past three years the college has been experimenting with 

 trap-nests with the view to finding one that would be inexpensive to install, 



easy to operate, 

 and that would 

 b e dependable. 

 In all, six differ- 

 ent types of 

 nests were test- 

 ed. Three were 

 m a n u factured 

 nests and the 

 other three were 

 inventions of the 

 college. One of 

 the latter de- 

 vices is here de- 

 scribed.

' -^ ihe mam dif- 



ficulty has been to get a nest that would be sure to work, would not catch 

 more than one hen at a time and that would be practicable to use on a 

 large scale. Some of the nests 

 were good, but were so large 

 and cumbersome that it did 

 not pay to operate them or to 

 give them the necessary room 

 in the poultry house. 



Plates I and II illustrate 

 the improved New York trap- 

 nest which the Department is 

 using at present. This nest 

 costs but little more to build 

 than the ordinary nest boxes 

 and can be used singly or run 



along in series, either under
