of them were more wakeful through the night, unless they sing in
their dreams. At this season one may hear at intervals numerous
bird voices during the night. The whip-poor-will was piping when I
lay down, and I still heard one when I woke up after midnight. I
heard the song sparrow and the kingbird also, like watchers calling
the hour, and several times I heard the cuckoo. Indeed, I am
convinced that our cuckoo is to a considerable extent a night bird,
and that he moves about freely from tree to tree. His peculiar
guttural note, now here, now there, may be heard almost any summer
night, in any part of the country, and occasionally his better
known cuckoo call. He is a great recluse by day, but seems to
wander abroad freely by night.

The birds do indeed begin with the day. The farmer who is in the
field at work while he can yet see stars catches their first matin
hymns. In the longest June days the robin strikes up about half-
past three o'clock, and is quickly followed by the song sparrow,
the oriole, the catbird, the wren, the wood thrush, and all the
rest of the tuneful choir. Along the Potomac I have heard the
Virginia cardinal whistle so loudly and persistently in the tree-
tops above, that sleeping after four o'clock was out of the
question. Just before the sun is up, there is a marked lull, during
which, I imagine, the birds are at breakfast. While building their
nest, it is very early in the morning that they put in their big
strokes; the back of their day's work is broken before you have
begun yours.

A lady once asked me if there was any individuality among the
birds, or if those of the same kind were as near alike as two peas.
I was obliged to answer that to the eye those of the same species
