seen October 14, 1896; Chicago, 111., October 3, 1895, October 9, 1896; 

 BrookvUle, Ind., October 13, 1879, October 16, 1886. In fall they 

 have lost their song and frequent the edges of woods and fields, brier 

 patches, thickets and clumps of weeds. They are then busy eating 

 weed seeds, of which they destroy great quantities. They migrate 

 chiefly through the Mississippi Valley, and thence many turn ofE 

 northeast to Labrador and Newfoundland where they breed abundantly. 

 Their scarcity and irregularity along the Atlantic Coast has been 

 noted. Its summer range is a little north of that of the next species, 

 consequently they in migrating pass them. It has been found breed- 

 ing at Eutland, Vt., Potsdam, N. Y., and in Oconto County, "Wis. 

 Mr. Nehrling says: "In northern Wisconsin, and especially in north- 

 em Michigan — ^in the Lake Superior region — ^this Sparrow is a rather 

 common summer bird." Mr. 0. B. Warren, however, has never found 

 them breeding at Palmer, Mich. Its food is principally weed seeds 

 and insects, though Audubon adds small mollusks to its bill of fare. 

 I suspect from its habits about our gardens and orchards that it will 

 be found to destroy many injurious insects that frequent such places.
