tion of yellow-browns, wood-brown, tawny-olive, cinnamon, 
raw sienna, raw umber, russet, etc. A not uncommon type pro- 
ducing perhaps the least attractive coloration. (e) Red-browns. 
mars, prouts, burn-umber, walnut, vandylse, chocolate and seal 
brown. The most common pigmentation, occuring in fully 
half of the eggs. (f) Subdued reds, rufous, brick, hazel, chest- 
nut, burnt sienna and claret brown. A not infrequent pigmen- 
tation and producing very rich combinations; usually when 
present at all, occurs more or less on all eggs of a set. Ap- 
pears most frequently on Minnesota specimens. 
A white ground shows off the pigments to the best advant- 
age, but the tinted grounds often aid the production of beauti- 
ful combinations. The most varied and brilliant series comes 
from Connecticut, though New Hampshire, Vermont, Massa- 
chusetts, Rhode Island, New York, Pennsylvania, Virginia ~ 
and in the west, Manitoba and Minnesota, produce many beau- 
tiful eggs, greatly eclipsing the series from which Major Ben- 
dire took his descriptions. Mr. Riley recently informed me 
that the U. S. National Museum now has a series of 76 eggs 
and the variations are very great. Most of them have come in 
since Bendire composed his work, and many of them are much 
handsomer than any he figured. My own personal experience 
in southeastern Pennsylvania has been that the eggs taken by 
myself pale into insignifcence in comparison to the brilliant 
examples taken by H. W. Beers in Connecticut. In descrip- 
tions, the blotches represent the larger, the spots the medium 
and the dot the smallest markings. In nearly all of the pairs 
visited by Beers, there has been a striking resemblance of eggs 
for two or often three years, and then perhaps a jump from 
one extreme to another: from very plain to the most remark- 
able type or vice versa. 
Chas. C. Richards describes a set taken at Norwich, Ct., 
May 15, 08, in which one of the eggs was a solid bluish-white 
like a Cooper's Hawk, only smaller, the other shell markings 
of lavender heaviest at the large end, and over this a few light 
brown spots and blotches. He finds that the texture of the 
shells of tis species is so porous that if the surface be damp-
