ground, with four eggs w'ell advanced in incubation. Being the first we have ever 
found in a situation of this kind we desired very much to secure a photograph of 
it. In this we experienced considerable difficulty and it was only by cutting a 
strip of wood out from the lower edge of the hole that we succeeded in making the 
eggs visible on the ground glass. Inspection show^ed the nest to be made of light- 
colored grasses and weed stems, and lined with the hair of various wild animals. 
After a long journey over the ridge, down through Glen Alpine Gorge, along 
Fallen Leaf Lake and Lake Tahoe we came into Bijou at midnight. Before we 
left for home on July 5 a nest of particular interest was found, one of the Pacific 
Wxghthdi.yi'k {Chordeiles virg:i>u'anHS hesperis) . This was found by Mr. Charles 
Young, on July 3, while riding horseback along one of the lower ridges southeast 
of Bijou. Returning with Mr. Young I found that the two fresh eggs were simply laid 
on the bare, rocky soil, surrounded by pine needles, the latter, however, not having 
been brought by the birds. A little pine .sapling close by gave the eggs some slight

.shelter. The elevation was about 6350 feet. On July 4 Heinemann and I accom- 
panied by Mr. Richard Duttke, who had just arrived, revisited the spot, and the 
photograph shown herewith was taken. 
An interesting addition to the Lake Valley checklist was the Bullock Oriole 
, first noted on the Bijou camp ground on June 7, and several 
times afterwards. This bird, or these birds, were without doubt stragglers from 
Carson Valley, Nevada, which lies just over the summit east of Bijou. The fact 
that this summit is but very little higher than Lake Valley, accounts, I believe, for 
the presence of the oriole, as well as the many other lower zone birds more or less 
abundant in Lake Valley, such as the Mourning Dove {Zenaidura macroura ca7'o- 
liiiensis), House Finch {Ccn'podacus mexicamis froiitalis), Western Bluebird 
{Sialia nicxica)ia occidentalis) and Western Meadowlark i^SturneUa negJecta^ .
