6. The nest is placed in the woods, in the fork of a bush, 

 not far from the ground. It is composed of leaves, grasses, 

 and roots, is often lined with feathers, and is finished early in 

 the season. One set of eggs contains from four to six, aver- 

 aging 1.10 X .80 of an inch. A specimen before me is blotched 

 and spotted, most thickly about the crown, with faint like, and 

 light sandy and yellowish brown ; others are darker.

 disposition, but seldom seen in any considerable numbers. W. B.
