There was but little wind and, hoping to see the big game that the flames might drive into the open, I innocently took my stand in the centre of the grassy stretch directly before the fire. This great smoky fire-billow, as I viewed it from the heights while I was descending, was advancing with a formidable crooked front about three miles across. The left wing was more than a mile in advance of the active though lagging right one. As I afterward learned, the difference in speed of the two wings was caused chiefly by topography; the forest conditions were similar, but the left wing had for some time been burning up a slope while the right had traveled down one. Fire burns swiftly up a slope, but slowly down it. Set fire simultaneously to the top and the bottom of a forest on a steep slope and the blaze at the bottom will overrun at least nine-tenths of the area. Flame and the drafts that it creates sweep upward. Upon a huge lava boulder in the grassy stretch I commanded a view of more than a mile of the forest-edge and was close to where a game trail came into it out of the fiery woods. On this burning forest-border a picturesque, unplanned wild-animal parade passed before me. Scattered flakes of ashes were falling when a herd of elk led the exodus of wild folk from the fire-doomed forest. They came stringing out of the woods into the open, with both old and young going forward without confusion and as though headed for a definite place or pasture. They splashed through a beaver pond without stopping and continued their way up the river. There was no show of fear, no suggestion of retreat. They never looked back. Deer straggled out singly and in groups. It was plain that all were fleeing from danger, all were excitedly trying to get out of the way of something; and they did not appear to know where they were going. Apparently they gave more troubled attention to the roaring, the breath, and the movements of that fiery, mysterious monster than to the seeking of a place of permanent safety. In the grassy open, into which the smoke was beginning to drift and hang, the deer scattered and lingered. At each roar of the fire they turned hither and thither excitedly to look and listen. A flock of mountain sheep, in a long, narrow, closely pressed rank and led by an alert, aggressive bighorn, presented a fine appearance as it raced into the open. The admirable directness of these wild animals put them out of the category occupied by tame, "silly sheep." Without slackening pace they swept across the grassy valley in a straight line and vanished in the wooded slope beyond. Now and then a coyote appeared from somewhere and stopped for a time in the open among the deer; all these wise little wolves were a trifle nervous, but each had himself well in hand. Glimpses were had of two stealthy mountain lions, now leaping, now creeping, now swiftly fleeing.
