 in a black oak crotch about 20 feet from the 

 ground. A bulky affair of twigs loosely piled 

 together, lined with a few pieces of bark 

 from 18 inches to 2 feet across top, 12 

 inches deep.

 age of set, 1.95 X 1.53. 



Nest of fine but long twigs of the larch, 

 lined with the bark of the Scotch pine, 

 placed in a larch tree 15 feet from the 

 ground, in the edge of a dense gro\'e of pine 

 and larch, near a house.

 some of the eggs): measure, 2.07x1.56;

Nest an old Crows' nest, placed by the 

 writer in a pine tree for a pair of Owls about 

 20 feet from where the set of 1-4 was taken 

 in 1 89 1 . The Hawks were the same pair as 

 in 1 8g I , for they were in the grove all winter. 

 .A quantity of twigs were added to the nest 

 by the Hawks, 



May 20, 1-2; slight, 1.96x1.55, 1.96 x 

 1.57. Eggs placed in a deserted Crows' nest

largest, 



1.57; smallest, 1.90x1.55. 



Both sets of 1-2 are a bluish white, uns]3ot- 

 ted ; I -4 has a number of large, reddish 

 blotches (blood?) scattered over the entire 

 surface of eggs; 1-5, by same bird, has at 



the large ends dark blotches, with a tinge 

 reddish. These are certainly shell marks. 

 The color becomes duller after incubation 

 has begun.
