Measurements cannot be had with any degree of accuracy. 
especially in diameter, on account of the nests’ irregularity ; 
but it varies from 11 to 30 inches in outside diameter, 36 aver- 
aging 19 inches. Outside depth 6 to 18 inches, averaging 10 
inches. Inside diameter 6 to 9 inches, averaging about 7.50) 
inches ; and inside depth from a fraction to 5 inches, the average 
2.50 inches. It is somewhat smaller and lacks the neatness of 
the Cooper’s Hawk nest. The exterior as well as the interior 
soon becomes flecked with the down feathers of the moulting 
birds and is a sure indication of its occupancy. 
A. C. Bent found a nest at Rehobeth, May 17, ’08, contain- 
ing three eggs 24 feet up in a small white birch which was 
but 4 inches in diameter immediately beneath a most insignifi- 
cant nest, flimsily built, about 14x12 inches outside and 6x7 
inches inside, lined with a few slabs of outer bark. Wm. B. 
Crispin, Salem, N. J., found a nest on May 27, '00, in a crotch 
of small pine, 15 feet up. The nest was small and flat, made 
of a few sticks, and lined with pine needles only. The nest was 
so small that it would probably have been overlooked but for 
the sitting bird. 
Derosirion—At Berwyn, Pa., one day intervenes deposi- 
tion, ordinarily, i.e. in a set of three eggs, the order is: first, 
third and fifth day. Sometimes two or more days intervenes.
