Slowly the little herd neared the rock and the lynx drew back, as if to lure them on. They were full of burning curiosity, but they had seen one spring, at least, and measured its power, and so kept at a respectful distance. Then one young caribou left the others and went nosing along the edge of the woods to find the trail of the queer thing, or get to leeward of the rock, and so find out by smell—which is the only sure sense that a caribou possesses—what it was all about. A wind seemed to stir a dried tuft of grass on the summit of the great rock. I put my glasses upon it instantly, then caught my breath in suppressed excitement as I made out the tufted ears of two or three other lynxes crouching flat on their high tower, out of sight of the foolish herd, but watching every movement with fierce, yellow, unblinking eyes.

The young caribou found the trail, put his nose down into it, then started cautiously back toward the rock to nose the other hole in the snow and be sure that it smelled just like the first one. Up on the rock the big lynx drew further back; the herd pressed close, raising their heads high to see what he was doing; and the young caribou stole up and put his nose down into the trail again. Then three living catapults shot over the high rim of the rock and fell upon him. Like a flash the big lynx was on his feet, drawing himself up to his full height and hurling a savage screech of exultation after the flying herd. Then he, too, shot over the rock, fell fair on the neck of the struggling young caribou, and bore him down into the snow.

"Then he, too, shot over the rock"

Upweekis is a stupid fellow. He will poke his big head into a wire noose as foolishly as any rabbit, and then he will fight savagely with the pole at the other end of the noose until he chokes himself. But no one could follow that wonderful trail in the snow, or sit with tingling nerves under the spruces watching that wild bit of fox-play, without a growing respect for the shadowycreature of the big round tracks that wander, wander everywhere through the winter woods, and without wondering intensely in what kind of savage school Mother Upweekis trains her little ones.
