rapid, it utters a shrill piercing note that may be heard to a 
great distance.

CHIMNEY SwaLLow.—The arrival of this species in the neigh- 
bourhood of Bottisham usually takes place about the fifteenth of 
April, as I have found by many years’ observation, but has been 
occasionally deferred till the twenty-second, which is the latest that 
I ever noticed. The first broods are fledged early in August, and 
towards the middle of that month they begin to collect into large 
flocks, which increase in numbers as the season advances and the 
time of departure draws near. This, with respect to the majority, 
takes place in the beginning of October, but stragglers may be 
seen a week or two longer. I once observed a white variety of this 
bird at Ely.
