three practically fresh eg'gs which were collected with the parent and which 
Joseph Grinnell pronounced typical iiioiitaiia. 
On May 29 1 took the first recorded eggs (a set of six) for Lake Valley 
of the Parkinan Wren ( Troglodytes acdon parkiiiaiii) with parent. The nest 
was first found on May 21 and was placed in a dead aspen 71 inches up. The 
cavity was extremely small and allowed very little opportunity for that exten-

willow, along a brook. The ne.st was flush with the surface and made of 
grasses lined with red cow-hair with which the green-brown eggs prettily con- 
trasted, The eggs were three in number and almo.st fresh. The flushing of 
the sitting bird led to the di.scovery of the nest. 
The second nest was along the same .stream four feet up in a lodge-pole
