Once, while I was seated at the foot of a Hemlock Spruce in one of the most inaccessible of the San Joaquin yosemites engaged in sketching, a reckless fellow came up behind me, passed under my bended arm, and jumped on my paper.

And one warm afternoon, while an old friend of mine was reading out in the shade of his cabin, one of his Douglas neighbors jumped from the gable upon his head, and then with admirable assurance ran down over his shoulder and on to the book he held in his hand.
Our Douglas enjoys a large social circle; for, besides his numerous relatives, _Sciurus fossor, Tamias quadrivitatus, T.Townsendii, Spermophilus Beccheyi, S.Douglasii_, he maintains intimate relations with the nut-eating birds, particularly the Clark Crow (_Picicorvus columbianus_) and the numerous woodpeckers and jays.

The two spermophiles are astonishingly abundant in the lowlands and lower foot-hills, but more and more sparingly distributed up through the Douglas domains,--seldom venturing higher than six or seven thousand feet above the level of the sea.

The gray sciurus ranges but little higher than this.

The little striped tamias alone is associated with him everywhere.
