Eggs pure white.
A Citizen of most parts of the world--northerly in summer, southerly in winter.
A Sky Sweeper [Illustration: Bank Swallow.] "Bankey is a sociable, useful little bird, living usually in great colonies.

I have seen a hundred of their holes in a single bank, all dug by these industrious little Swallows with no other tools than their feeble beaks and claws.

When the young from these nests are learning to fly the old birds are darting to and fro all day long to teach them how to use their wings, and the bank seems like a bustling village; every bird has something to do and say, and they always try to do both at once.

If any one asks you why House People should love and protect Swallows, even if you have forgotten the names of many of the insects they destroy, remember to answer--'Swallows eat mosquitoes!'".
