Pine 
nest 
where we were sitting, always keeping together and flying 
from an apple tree to some low willows. I was puzzled to 
account for the regularity of their movements until I followed 
them and found that one of them, a female, was getting silk 
from a tent caterpillar's nest in the apple tree and carrying 
it to her own nest among the willows. Even then the mystery 
was not wholly solved for the other two birds were apparently 
males who seemed on the best of terms but each of v<rhom kept 
close to the female bird at all times. Is it possible that 
she had two husbands? 
Warbler's The son § a Pine Warbler on the hill above us 
tempted me to look for the nest. I came on the female very 
soon and followed her for several minutes but finally lost 
sight of her. After looking for the nest in all the most 
promising trees I found it, at length, in a small, isolated 
pitch pine Yirhieh §tdod near the river bank directly in front 
of a summer camp house or shanty. It was built on a long 
horizontal branch near the end and directly above a cluster 
of three cones which served admirably to conceal it from 
beneath, while the pine needles nearly covered it above. It 
was barely 12 feet from the ground and we had little difficulty 
in getting at it by throwing a rope over the branch and pulling 
it down sufficiently low to be reached from the top of a 
rude tripod which we made by lashing the ends of three sticks 
together. There were three eggs and a young bird just hatched,
