[Illustration: NEST OF RED-EYED VIREO.]

As I was about leaving the woods, my hat almost brushed the nest of
the red-eyed vireo, which hung basket-like on the end of a low,
drooping branch of the beech. I should never have seen it had the bird
kept her place. It contained three eggs of the bird's own, and one of
the cow-bunting. The strange egg was only just perceptibly larger than

nevertheless.

The woods hold not such another gem as the nest of the humming-bird.
The finding of one is an event to date from. It is the next best thing

intruding upon some one's privacy; and following it with my eye, I
soon saw the nest, which was in process of construction. Adopting my
usual tactics of secreting myself near by, I had the satisfaction of
seeing the tiny artist at work. It was the female, unassisted by her
