 lt was three indies across, one and one-fourth inches deep, 

 and was made of pieces of dried weed-stems and rubbish. There 

 were three eggs, in which incubation had begun. 



On June 27, a nest of tiie spotted sandpiper was found on 

 the sandy beach at a point near the mouth of Flathead Eiver. 

 It was in a willow bash about twenty feet from the water, made 

 of drift rubbish, measurements as in the preceding instance. 

 This nest contained four fresh eggs. 



A set of eggs is shown in Plate XIV.

Fourteen nests of olive-backed thrush, Turdus ustulatu.f 

 swainsonii, were examined in the region under consideration, in 

 1901. Of these, the highest site was eight feet, the lowest 

 three and one-half feet, the average being six and one-half 

 feet from the ground. Ten of these nests contained four eggs 

 or young as the complement, and of the remainder, two held 

 three fresh eggs, which might constitute incomplete sets. ISTine 

 of these nests were in upright crotches, of which eight were 

 in maple saplings and one in a birch; the other nests were in 

 firs, on horizontal branches beside the main stem. The first 

 was found June 18, with fresh eggs; the last one contained 

 eggs quite advajiced in incubation, July 5. 



A nest of the willow thrush, Turdus fuscescens salicicola, 

 was found in the swamp-woods bordering the Jocko Eiver at 

 Selish, on June 16. It was made on a heap of dried and decayed 

 leaves on fallen branches, one foot from the ground. The 

 nest was similar in construction to that described on page 12. 

 It contained four eggs, incubation well advanced. From the 

 frequent notes heard, it seems that this species is more com- 

 mon than we supposed from our observations in the preceding 

 season. 



A nest of the American dipper, Cinclus mexicanus, was taken 

 at Lake McDonald, from a shelf of rock about four feet above 

 the water of the lake shore. It was constructed entirely of 

 green moss, and was situated in an angle of the rock, the 

 site giving it an ellipsoidal form. It was nine and one-half 

 inches long, and seven and one-half inches high, with a width of 

 seven inches from front to back. The entrance was a sub-cir- 

 cular hole three inches in diameter, near the middle of the
