Columbine Lake is a typical mountain lake of Fig. 55.

Along the west shore extends a narrow strip of boggy ground lying between the hevy timber and the water's edge and covered with a variegated growth of rank grass, moss, low scattered bushes and down timber. As I made my way around the lake two Spotted Sandpipers fluttered from their nests each containing four eggs, and a few feet farther on, in a precisely similar location a Orav-headed Junco flusht noisily from under my very feet.

The parent bird flew directly to the dense pine timber close by, where it
