A great cake had driven its nose into the bed of the river thirty feet below and was struggling to up-end. All the frigid flood behind crinkled and bent back like so much paper. Then the stalled cake turned completely over and thrust its muddy nose skyward. But the squeeze caught it, while cake mounted cake at its back, and its fifty feet of muck and gouge were hurled into the air. It crashed upon the moving mass beneath, and flying fragments landed at the feet of those that watched. Caught broadside in a chaos of pressures, it crumbled into scattered pieces and disappeared.
"God!" The baron spoke the word reverently and with awe.
Frona caught his hand on the one side and her father's on the other. The ice was now leaping past in feverish haste. Somewhere below a heavy cake butted into the bank, and the ground swayed under their feet. Another followed it, nearer the surface, and as they sprang back, upreared mightily, and, with a ton or so of soil on its broad back, bowled insolently onward. And yet another, reaching inshore like a huge hand, ripped three careless pines out by the roots and bore them away.
Day had broken, and the driving white gorged the Yukon from shore to shore. What of the pressure of pent water behind, the speed of the flood had become dizzying. Down all its length the bank was being gashed and gouged, and the island was jarring and shaking to its foundations.
"Oh, great! Great!" Frona sprang up and down between the men. "Where is your fake, baron?"
"Ah!" He shook his head. "Ah! I was wrong. I am miserable. But the magnificence! Look!"
He pointed down to the bunch of islands which obstructed the bend. There the mile-wide stream divided and subdivided again,—which was well for water, but not so well for packed ice. The islands drove their wedged heads into the frozen flood and tossed the cakes high into the air. But cake pressed upon cake and shelved out of the water, out and up, sliding and grinding and climbing, and still more cakes from behind, till hillocks and mountains of ice upreared and crashed among the trees.
"A likely place for a jam," Jacob Welse said. "Get the glasses, Frona." He gazed through them long and steadily. "It's growing, spreading out. A cake at the right time and the right place . . ."
"But the river is falling!" Frona cried.
The ice had dropped six feet below the top of the bank, and the Baron
Courbertin marked it with a stick.
