In one instance I found two nests (nearly two feet apart), 
which I had often seen, being tended by only one fish. I 
have no doubt, from long familiarity with the species, that 
he was one of the two fish I had often seen, and was 
imposing on himself the task of hatching out the eggs 
belonging to a defunct neighbour. 
A very tame Kestrel Hawk given to me, and allowed 
the use of her wings for the first time when a year old, 
was scared away six months after, and took up her abode 
in a valley near the town, where I watched from time to 
time her progress in learning to fly well. She came to

nose against the end of a broken root (of about the size of 
a man’s thumb), and thus completely close one nostril. 
The cow then blew through the other nostril and thus 
violently cleared it; and immediately afterwards stopped
