lessly together. One was placed undera rock as large as a doghouse, 
and in it were four young ones which scampered off while I was 
removing the rock. The birds become chapped and ragged, and 
present an odd appearance.

17. Troglodytes aedon. House Wren. 
As I was passing by a low hut dug into a hill, on the 25th of July, 
1869, Isaw a pair of these wrens enter the door or opening. I fol- 
lowed them but could not find them; as I turned to go out both birds 
passed me into the open air. I watched them several days and saw 
them go in with flies and bugs in their bills, so I entered again and hid 
myself in the large chimney; the birds came in and I saw one go © 
into a small hole in the roof of sage brush. ,I put my hand in the hole 
and found there were five young ones. I remained in that vicinity 
some time and soon saw the young follow their parents.
