Lake. The nest was ill-concealed, about four feet from the 
ground, and the bird left it when I approached. Ata short dis- 
tance it resembled a chipping sparrow’s, but was composed out- 
wardly of fine hemlock twigs, neatly woven, and was lined with 
hair and fibres. There were four fresh eggs which were boldly 
marked, rather than spotted, with blotches of a dark brick-red ona 
creamy ground. I saw the bird leave the nest three times and 
identified it by the yellow markings and black on side of head.
