It came toward us, gathering more and more material, until finally it was within thirty
feet of us, apparently not caring at all for our presence; then it stopped, put down
its load, and flew away, after a moment of arrangement. We went forward and found the
nest, almost completed. We paid ourselves and each other many impressive compliments,
all bearing upon how good we were. We were careful not to remain long at the nest.
Of course we had our cameras with us, but had no occasion to use them today.

From there we followed the Belt Line to The Tangle which was literally alive with
robins, juncoes, Harris sparrows, tree sparrows, bluebirds; there were also present a Carolina nuthatch and a downy woodpecker. Following the strip of woods to the County Farm, we amused ourselves gathering galls
from a small oak stump surrounded with sprouts, and examining them. Most of them were

One of the striking events of the day was in the woods south of Poppleton, where we
chanced to see an albino tree sparrow, pure white except for a feather or two in the tail and a little about the head.

Trostler ventured an experiment which he says is a favorite with him. Finding a resonant place
on an oak — a dead, dry surface — he tapped upon it vigorously with the end of small
pocket knife. After a few repetitions of this a downy woodpecker came charging through the tree-tops looking for
