558 THE BIRDS OF MAINE 



flat-bladed grass, with finer grasses and a few weed stalks, 

 and all through this outer wall was interwoven a few small, 

 dead, white maple leaves. The inner wall was composed of 

 fine grasses, and the inner lining contained a few horsehairs. 

 It was a very neat, compact nest, well built to protect the eggs 

 from the dampness from the moist ground where it was placed. 

 It measured, outside diameter, five inches; inside diameter, 

 two inches; outside depth, three and one-half inches; inside 

 depth, two inches. 



The eggs, four in number, were fresh. The general color 

 was white with a rosy blush, dotted with reddish brown spots, 

 most thickly sprinkled about the larger end, and does not 

 much resemble the average set of Yellow-throat's eggs, and 

 measured 0.71 x 0.54, 0.70 x 0.54, 0.71 x 0.54, 0.71 x 0.53. 



The last days of June, 1904, I saw a pair of Mourning 

 Warblers feeding young on a side hill near a ravine in Wins- 

 low, not far from the Kennebec River. 



Mr. Dana Sweet, of Avon, Franklin County, sends me the 

 following from his note book: " May 24, 1902, saw a Mourn- 

 ing Warbler about three miles west of my home, on low land 

 near the Sandy River. May 24, 1903, went to the above 

 locality and saw a Mourning Warbler singing on the limb of 

 a tree. June 17, heard its song near the same locality. June 

 2 and 4, 1904, I heard one or two Mourning Warblers near 

 Tim Brook, in Eustis." This Warbler doubtless breeds rarely 

 in Mr. Sweet's locality. 



This Warbler seems to stay about near the locality after the 

 young leave the nest ."(Swain).
