The driver pulled up his horses with a jerk, and none too soon. Up scrambled a huge brown, or “cinnamon” bear from the bank of the river, not a hundred yards ahead of them. She jumped a log which lay along the embankment, and crossing the road, began to climb the steep, wooded hill on their left.

Presently a woolly cub, about the size of a half-grown Newfoundland dog, came hurrying after her. He tried to climb the log as she had done, but after straining to get over, exactly like a boy endeavoring to mount a horizontal bar, tumbled backward into the brush.

Fred and Tom cheered him on, and the second attempt succeeded. Down he went, head over heels, into the dusty road, and then how he did scramble up hill after his mother! The boys laughed and shouted to him until both bears were out of sight among the pines, far up the mountain slope.

The horses had acted bravely during this scene, merely standing with quivering limbs and alert ears until little Bruin and his mother had passed.

At Yellowstone Lake the boys hastily organized a fishing excursion, and came back with a fine string of trout, averaging a pound to a pound and a half apiece. In the evening they took the girls out on the lake for a moonlight row. The songs they sang were of a gentler and more plaintive character than usual; for they realized that the beautiful journey over gulf and glacier, and through Wonderland, was fast drawing to a close.

“Row, brothers, row!” rang out Pet’s sweet soprano; and even Fred’s “Jolly boating weather” had an undertone of sadness, as the chorus came in, full and strong, at the end of each verse. Ah! how far ahead a “good-by” casts its shadow. How will it seem to reach a land where the word is not known!

“The rapids are near, and the daylight’s past,” sang Pet; while the moonlight quivered on the waters of the strange, wild mountain lake.

I must hurry on, myself, in my story of those fair, sweet days and silvery nights; for I find myself lingering only too long among the hills—dreading perhaps, as I trust some of you do, my boy and girl readers, the parting from the glad young lives that, in the course of these six volumes, have become a part of my very own. Yes, my manly Randolph, impulsive, good-hearted Tom, merry Kittie, golden-haired Pet, and sweet, gentle “Captain Bess,” I must leave you all too soon, in the fair morning-land where hearts beat warmly and young faces glow with mirth and noble resolve; whither in very truth, I have tried, poorly and feebly but most earnestly, to take the real, living boys and girls who have gathered around the pine-cone fires and many a time have sent me words of cheer from their own far-away firesides, year after year. God bless them, every one!

Randolph and Fred were loath to leave the fine fishing-grounds of the Lake, but the word was “Onward!” and another day’s ride took the party away from those picturesque shores to the Grand Cañon of the Yellowstone.

On horseback they rode slowly along the banks of this mighty ravine, whose tawny flanks have given the river its name. One moment the girls were speechless with laughter over Tom’s dismay as his horse began to slide down a steep descent; the next they caught their breath with wonder and awe, as they came out on the brink of the mighty cañon, and, making their way on foot to the very edge of a jutting promontory, gazed downward into the fearful depths of a sheer thousand feet below.
