in depth externally; internally it was two in length, one and a 

 half in width, and one and thirty-five hundredths inches in 

 depth. The walls were more than half an inch thick in some 

 places and the bottom almost a full inch thick. It was com- 

 posed of shreds of grayish brown and light brown bark, inter- 

 woven and decorated exteriorly with strips of paper birch 

 and willow catkins, held in place by shreds of Usnea. The 

 eggs were pure white sparsely spotted with burnt umber, 

 chocolate and black, the markings small and rounded. On 

 two of the eggs the markings are generally distributed save at 

 the small end, while on the other they are confined to the large 

 end. The eggs measured 0.80 x 0.54, 0.81 x 0.53, 0.79 x 0.54. 

 A nest taken by Mr. Thompson (Mr. Seton, as he is now known) 

 in Manitoba was only eight feet from the ground in a small 

 willow, but it seems very likely that most nests of this species 

 are situated well up in trees. Only two really authentic nests, 

 Mr. Brewster's and Mr. Thompson's, seem to be known.
