"But it must be three o'clock or more. When can we hope to get back home?" murmured Barbara, glancing down the trail they just left. "Too late to worry about that now," said Eleanor. "I plan to see Grizzly Slide and then camp somewhere," said Polly. "That is the best thing, now," added Anne. "You don't mean to sleep out in this awful wilderness, do you?" gasped Barbara. "No, we're going to engage a suite of rooms at the 'Queen Victoria' for to-night!" jeered Eleanor. "I hope to reach the Slide and ride back to those Falls for camp. We have fish and pasture and soft moss there," said Polly. "Ideal place, too," approved Anne. "But the wild beasts, and, oh, suppose a rattler comes along while we are asleep?" almost sobbed Barbara. "He'll steer clear of you, Bob!" retorted Eleanor. "Come on, girls, don't waste time arguing, or we'll camp on top of the peak, yonder," laughed Polly, jumping back into her saddle and urging Noddy along the way. Although Grizzly Slide was but four miles from the blaze, the trail was so rough that the horses had to go slowly. Too, the rarefied air strained the animals' hearts and Polly advised frequent halts to rest the heavily breathing beasts. During those four miles, the trail often opened from the heavy timber and gave a glimpse of far-off valleys, and dreadfully nearby abysses that made one feel that one was on top of the world. Even the pines in the nearer crests and clefts looked like wisps of green--so small they appeared from the tremendous height. The trail finally led through a thick forest of lodge-pole pine that looked interminable, but suddenly ended at a line as if it had been purposely cleared away. The riders all sat in silent awe at the sight before them. They had reached Grizzly Slide! The snow-capped peak, reaching an altitude, from the clearing where they stood, of at least a thousand feet sheer up, dazzled their eyes in the bright sunshine. To the left of the peak, the sides dropped down almost perpendicularly to the level floor of a valley many thousand feet below. To the right, the snow-fields stretched across a vast area before any timber could be seen on the downward slope. The snow of the Slide was continually melting in summer and furnishing icy streams that cut through in every direction to reach the vales far down. The temperature was almost at freezing point near the peak, and the girls quickly donned their sweaters which had been packed in Choko's panniers. In removing the sweaters, Polly accidentally pulled out a heavy coil of rope, but hung it back on one of the knobs of Choko's harness instead of buckling it inside the pocket. Well she did, too. "Come on, girls, I want to see what that blue line is over on the ice-field," said Polly, starting up the Slide. The horses were sharp-shod and sure-footed, so the girls rode as safely as if on the mossy trail, but they had not gone far before Polly began murmuring to herself. "What's the matter?" wondered Anne, aloud.
