Here is the fashion in which a mountain stream gets down from the perennial pastures of the snow to its proper level and identity as an irrigating ditch. It slips stilly by the glacier scoured rim of an ice bordered pool, drops over sheer, broken ledges to another pool, gathers itself, plunges headlong on a rocky ripple slope, finds a lake again, reinforced, roars downward to a pothole, foams and bridles, glides a tranquil reach in some still meadow, tumbles into a sharp groove between hill flanks, curdles under the stream tangles, and so arrives at the open country and steadier going. Meadows, little strips of alpine freshness, begin before the timberline is reached. Here one treads on a carpet of dwarf willows, downy catkins of creditable size and the greatest economy of foliage and stems. No other plant of high altitudes knows its business so well. It hugs the ground, grows roots from stem joints where no roots should be, grows a slender leaf or two and twice as many erect full catkins that rarely, even in that short growing season, fail of fruit. Dipping over banks in the inlets of the creeks, the fortunate find the rosy apples of the miniature manzanita, barely, but always quite sufficiently, borne above the spongy sod. It does not do to be anything but humble in the alpine regions, but not fearful. I have pawed about for hours in the chill sward of meadows where one might properly expect to get one's death, and got no harm from it, except it might be Oliver Twist's complaint. One comes soon after this to shrubby willows, and where willows are trout may be confidently looked for in most Sierra streams. There is no accounting for their distribution; though provident anglers have assisted nature of late, one still comes upon roaring brown waters where trout might very well be, but are not.
