feet. In 1882, the first was seen over Wolf River March 29. 
Two, April 1. A few the following days. April 6, small 
companies of 4 or 5 in several places. The 7th, abundant every¬ 
where. In autumn millions were seen flying over the rivers, 
most on July 22. Only a few in August. The last probably, 
Sept. 6. In 1883 the first, April 7. A few the day after. 
Many the 9th. In autumn most about July 20. This swallow was 
in the habit of building in our bird-boxes. In 1882, it ap¬ 
peared not to find them till late in May. Two pairs built. First 
egg June 10. In 1883, several visited the boxes at favorable 
times immediately after arrival. First egg May 27. In the 
boxes there were 4 and 5 eggs. M. from 2 nests L. 21-22. B.

W. 101. T. 50. In 1882 none shot before May 12. No great 
number seen at any time. Several (nearly a score) built in a sand 
bank in one of the turns of Wolf River (in Sec. 8). It was plain 
by the many holes unused that the colony had formerly been 
much larger. But the river breaks down great pieces of the 
bank every year. In 1883 a single one of this swallow was seen 
late in May; but none bred. For want of suitable breeding places 
it must probably give up breeding in the Daily Beat.

L. 135. E. 295. W. 110. T. 54. B. 6. Several bred on the rivers. 
In 1883 I knew seven places where they must have had nests. 
At least two pairs built in the vicinity of our house, where they 
were seen almost daily. May 17 and the following days they 
got feathers in our hen-yard. April 24, 1882, three were fly¬ 
ing over Wolf River. One alighted on a dry branch and was 
shot. In 1883, none seen before May 4. King has met with 
this swallow only once in Green Lake Co. Cooke has not seen 
it in Jefferson Co. 
132. Ainpelis cedrorum (Vieill.). XX Breeds in great num¬ 
bers in woods and gardens, but oftenest in young trees in or 
near the water. Of 19 nests, 12 were over water. Though 
oftenest in a fork, a single one was found on a horizontal 
branch. Of 19 nests 18 were in trees, 1 in a beech bush 
4J feet from the ground. Ten nests were in maple, 5
