on June 17. The material used in the construction of the nest 
is coarse grass with a lining of finer grass. 
584. Swamp Sparrow. 
Melospiza georgiana (Lath.). 
On May 26, a nest and five eggs, thought to belong to this 
bird, were found hut the identification was not satisfactory. 
Eggs from the set were sent to the 1 Smithsonian Institution, how¬ 
ever, and it was decided that they were probably eggs of the 
Swamp Sparrow. 
The nest was situated on the ground, hidden in a clump of 
grass. Low prairie, not far from the border of a slough, was 
the locality chosen. The body of the nest is composed of coarse 
grass-stems and sticks, while the lining consists entirely of very 
fine grasses, the branching ends of which show them to be the 
tops. Although sunk a little way into the earth, the nest is sub¬ 
stantially built and is compact. 
The hollow is well rounded and rather deep. The measure¬ 
ments of the nest are: inside depth, one and three-eighths inches; 
inside diameter, two and one-fourth inches ; outside depth, two 
and one-fourth inches ; outside diameter, three and one-fourth 
by four inches. 
When the eggs were found, May 26, incubation had not com¬ 
menced. In color they are of a light bluish tint rather thickly 
spotted with reddish brown and a few obscure markings of pur¬ 
ple. The eggs are much more heavily marked at the larger end 
and, on three of the specimens, the spots so near together as to 
entirely cover the bluish ground-color. The spots are clouded, 
not clear and distinct. The five eggs measure: .75x.54; .75x 
.54; .74x.54; .74-X.54; .75x56. 
595. Dose-breasted Grosbeak. 
Zamelodia ludoviciana (Linn.). 
This rather handsome bird, though not at all common, was 
occasionally seen. Two individuals were observed about the 
border of a lake surrounded by timber. Ho nests w T ere found.
