some sparingly dotted and speckled over tlie whole shell, and some have a wreath of confluent marks 
about the crown. Others, and this is the usual pattern, have a small patch of confluent marks at 
the base, and from the periphery of this patch the marks become less and less plentiful as the point is ap- 
proached. They measure in long-diameter, from .69 to .78, and in short-diameter, from .53 to .58. The 
average is about. .75 x .56. The largest egg of three sets is .77 x .58, the smallest .69 x .53.

REMARKS : 
The nest and eggs illustrated on Plate LIII, Fig. I, were discovered the last of May, 188J. I was 
walking leisurely along a small ditch which drained a held of wet grass-land, and was just in the act of 
stepping across it, when a small bird flew from under me. I stopped, stooped down, and, after some 
search, found a little nest hidden under a bunch of long grass. I retired a, convenient distance, and 
awaited the return of the owner. In about fifteen minutes she came back and entered the nest. I at 
once approached, so that I could see the bird. My conjecture was verified, it was a Swamp Sparrow. 
The bird was finally flushed and shot, and the nest and its five eggs were carefully lifted from the 
ground and carried home. This is the only nest of the species I have found, although I have frequently 
searched for it. The kind of country inhabited by this Sparrow, its retiring habits, and general incon- 
spicuousness, all combine to make its home difficult to find, and its habits hard to study. Even in sec- 
tions where it is common, it is but infrequently seen, and it might breed and remain throughout the year 
in many localities in the State and escape observation by any one able to distinguish it from other 
Sparrows. 
In the illustration the nest is shown turned over on its side, as this position better shows its size, 
shape, and structure. It is made principally of coarse grasses and frayed weed-stems — a few rootlets are 
to be seen in the foundation, and the lining is composed of grasses. The diameter of the cavity is two 
inches, its depth, one and one-half inches. When in position, the rim of the nest was on a level with 
the surrounding sod, and a long tuft of grass concealed it from above, and protected it from the weather. 
During its migration the Swamp Sparrow is seen in uplands as well as in swampy districts, and 
often in company with other Sparrows. It has no song except during the nesting season. At this time 
it has an animated melody which it frequently utters from the top of some low hush, very much after 
the manner of the Song Sparrow, but its notes are by no means so attractive. The history of the 
domestic life of the Swamp Sparrow is yet to be written.
