1887] Zoology. 779 
In a ravine which has a spring pool in it I placed two pairs of 
 blue-wing teal. One of these birds was the mother of the rest, 
and was raised by a man in Iowa, but no eggs have been laid by 
em. 
My pintail duck made her nest on the ground ina clump of 
ferns, and set on seven eggs. The day that she was due to 
hatch she disappeared, and no trace of her, the young, or even 
the egg-shells, remain. We think she escaped somewhere, per- 
haps over the netting, for I have seen a wood-duck, although 
pinioned, go over a wire netting, by means of feet and wings, 
when first placed in-strange quarters. They would go up with 
a sort of running fly and fall on the other side. 
It is possible that, had the wood-ducks been turned out in 
pairs, and no odd drakes been placed with them, the result 
would have been better. There is a great deal of natural food 
that they can eat; they prefer corn to anything else and eat that 
y first; next they take wheat, and only eat the oats when nothing 
else is left. j s 
- Next year I hope to try again under slightly different circum- 
j oes, such as proper mating and different food, and in the 
mean time I will be glad to have the experience of others in this
