small ones. To be sure, the birds found some insect 
food, but this was soon exhausted. Small pens have 
given entire satisfaction for wintering quail and grouse, 
the only difficulty being wet and dampness when snow 
melts. The pen should be kept entirely dry, and should 
be open to the fresh air. 
A better comprehension of the mating and nesting 
processes of the quail and ruffed grouse is very nec- 
essary. The breeding of the grouse is complicated by 
the uncertain and quarrelsome temper of the male. The 
problem of hatching, like that of food, requires further 
study. Meantime, of course, the work of bacterio- 
logical investigation must be kept up, for one of the 
first problems in rearing these birds is to understand 
the diseases to which they are subject under these new 
and unnatural conditions. 
The success of the Sutton Farm with pheasants has 
been better than with our native game, but even so has 
not been at all satisfactory.
