June 13. — We left Phillips Station at half past seven this morn- 

 ing and arrived at Bijou, on Lake Tahoe, at one o'clock in the 

 afternoon. On the way, near the Sierra House, four feet up in a 

 small tamarack by the roadside, I found another nest of Dendroica

 The usual species were in evidence, and I noted the following 

 nests : Spizella socialis arizonce, three eggs, incubation begun ; 

 Actitis macularia, three eggs, fresh; Hydrochelidon surinamensis, 

 nest on floating driftwood, two eggs, partly incubated.

 observed to-day was a Russet-backed Thrush (Hylocichla ustulata 

 ustulata). This is the first one I have seen on the floor of the

June 16. — We found a nest of the Mallard (Anas boschas) 

 to-day in a wooded swamp. The nest was placed on one of the 

 numerous and regular mounds, the origin of which I do not know, 

 and the seven practically fresh eggs rested on a warm lining of
