composed entirely of grass; when compared with other tree nests 
it is conspicuously flimsy and light-coloured, the latter effect being 
due to the absence of the black fibrous roots so commonly used as 
lining; the eggs are among the most beautiful of any produced by 
the sparrows; when first the discoverer draws aside the bush and 
exposes the nest with its complement, his feelings are as of finding 
an exquisite casket of jewels; although this is one of the most com- 
mon of our sparrows, and although on the scrubby plain between 
the Duck mountain and the Assiniboine in early June, I could have 
found as many as four or five nests in an hour’s walk, the treasure- 
trove feeling in connection with the eggs continues in full force. I 
infer from the above and other observations that the shattuck 
bunting breeds twice, if not three times each season with us; it 
leaves the ‘‘big plain” about the end of September. (E. T. Seton.) 
Builds in rose bushes, snowberry and wolf-willows generally from 
one to two feet from the ground; in size it is about three inches in 
diameter, but the cavity is less than two inches across. The nest 
is built of the stems of finer grasses and quite an oxen structure lined 
inside with coarse dark horse-hair, other nests were lined with 
white hair; in June, 1896, two nests were taken at Sewell, Manitoba, 
each contained four eggs and was built in bushes of dwarf birch, 
Betula glandulosa. (Macoun.) °
