By July and August the slender spires of the tall mountain larkspur are conspicuous along the watercourses of the Sierras, where they are usually found in the company of their near relatives, the monk's-hoods and the gay scarlet columbines. A ramble down one of these mountain streams affords a succession of most delightful surprises. Willow copses, alternating with tangles of larkspur, great willow-herb, and monk's-hood, are followed by open, velvety meadows, starred by white and blue daisies, or diversified by the pure spikes of the milk-white rein-orchis, or the lovely blossoms of the pink mimulus; while further down, the stream perchance suddenly narrows and deepens, flowing by some jutting rock-wall, resplendent with crimson pentstemons or brilliant sulphur-flowers.
