"And my father just as bull-headed," she smiled. "But hadn't you better change? There are spare things in the tent."
"Oh, no." He threw himself down beside her. "It's warm in the sun."
For an hour they watched the two men, who had become mere specks of black in the distance; for they had managed to gain the middle of the river and at the same time had worked nearly a mile up-stream. Frona followed them closely with the glasses, though often they were lost to sight behind the ice-ridges.
"It was unfair of them," she heard St. Vincent complain, "to say they were only going to have one more try. Otherwise I should not have turned back. Yet they can't make it--absolutely impossible."
"Yes . . . No . . . Yes! They're turning back," she announced. "But listen! What is that?"
A hoarse rumble, like distant thunder, rose from the midst of the ice. She sprang to her feet. "Gregory, the river can't be breaking!"
"No, no; surely not. See, it is gone." The noise which had come from above had died away downstream.
"But there! There!"
Another rumble, hoarser and more ominous than before, lifted itself and hushed the robins and the squirrels. When abreast of them, it sounded like a railroad train on a distant trestle. A third rumble, which approached a roar and was of greater duration, began from above and passed by.
"Oh, why don't they hurry!"
The two specks had stopped, evidently in conversation. She ran the glasses hastily up and down the river. Though another roar had risen, she could make out no commotion. The ice lay still and motionless. The robins resumed their singing, and the squirrels were chattering with spiteful glee.
"Don't fear, Frona." St. Vincent put his arm about her protectingly. "If there is any danger, they know it better than we, and they are taking their time."
"I never saw a big river break up," she confessed, and resigned herself to the waiting.
The roars rose and fell sporadically, but there were no other signs of disruption, and gradually the two men, with frequent duckings, worked inshore. The water was streaming from them and they were shivering severely as they came up the bank.
"At last!" Frona had both her father's hands in hers. "I thought you would never come back."
"There, there. Run and get dinner," Jacob Welse laughed. "There was no danger."
"But what was it?"
"Stewart River's broken and sending its ice down under the Yukon ice. We could hear the grinding plainly out there."
"Ah! And it was terrible! terrible!" cried the baron. "And that poor, poor man, we cannot save him!"
"Yes, we can. We'll have a try with the dogs after dinner. Hurry, Frona."
But the dogs were a failure. Jacob Welse picked out the leaders as the more intelligent, and with grub-packs on them drove them out from the bank. They could not grasp what was demanded of them. Whenever they tried to return they were driven back with sticks and clods and imprecations. This only bewildered them, and they retreated out of range, whence they raised their wet, cold paws and whined pitifully to the shore.
"If they could only make it once, they would understand, and then it would go like clock-work. Ah! Would you? Go on! Chook, Miriam! Chook! The thing is to get the first one across."
Jacob Welse finally succeeded in getting Miriam, lead-dog to Frona's team, to take the trail left by him and the baron. The dog went on bravely, scrambling over, floundering through, and sometimes swimming; but when she had gained the farthest point reached by them, she sat down helplessly. Later on, she cut back to the shore at a tangent, landing on the deserted island above; and an hour afterwards trotted into camp minus the grub-pack. Then the two dogs, hovering just out of range, compromised matters by devouring each other's burdens; after which the attempt was given over and they were called in.
During the afternoon the noise increased in frequency, and by nightfall was continuous, but by morning it had ceased utterly. The river had risen eight feet, and in many places was running over its crust. Much crackling and splitting were going on, and fissures leaping into life and multiplying in all directions.
"The under-tow ice has jammed below among the islands," Jacob Welse explained. "That's what caused the rise. Then, again, it has jammed at the mouth of the Stewart and is backing up. When that breaks through, it will go down underneath and stick on the lower jam."
"And then? and then?" The baron exulted.
"La Bijou will swim again."
As the light grew stronger, they searched for the man across the river. He had not moved, but in response to their rifle-shots waved feebly.
"Nothing for it till the river breaks, baron, and then a dash with La Bijou. St. Vincent, you had better bring your blankets up and sleep here to-night. We'll need three paddles, and I think we can get McPherson."
"No need," the correspondent hastened to reply. "The back-channel is like adamant, and I'll be up by daybreak."
"But I? Why not?" Baron Courbertin demanded. Frona laughed. "Remember, we haven't given you your first lessons yet."
"And there'll hardly be time to-morrow," Jacob Welse added. "When she goes, she goes with a rush. St. Vincent, McPherson, and I will have to make the crew, I'm afraid. Sorry, baron. Stay with us another year and you'll be fit."
But Baron Courbertin was inconsolable, and sulked for a full half-hour.
Chapter XXIV
"Awake! You dreamers, wake!"
Frona was out of her sleeping-furs at Del Bishop's first call; but ere she had slipped a skirt on and bare feet into moccasins, her father, beyond the blanket-curtain, had thrown back the flaps of the tent and stumbled out.
The river was up. In the chill gray light she could see the ice rubbing softly against the very crest of the bank; it even topped it in places, and the huge cakes worked inshore many feet. A hundred yards out the white field merged into the dim dawn and the gray sky. Subdued splits and splutters whispered from out the obscureness, and a gentle grinding could be heard.
"When will it go?" she asked of Del.
"Not a bit too lively for us. See there!" He pointed with his toe to the water lapping out from under the ice and creeping greedily towards them. "A foot rise every ten minutes."
"Danger?" he scoffed. "Not on your life. It's got to go. Them islands"--waving his hand indefinitely down river--"can't hold up under more pressure. If they don't let go the ice, the ice'll scour them clean out of the bed of the Yukon. Sure! But I've got to be chasin' back. Lower ground down our way. Fifteen inches on the cabin floor, and McPherson and Corliss hustlin' perishables into the bunks."
"Tell McPherson to be ready for a call," Jacob Welse shouted after him. And then to Frona, "Now's the time for St. Vincent to cross the back-channel."
The baron, shivering barefooted, pulled out his watch. "Ten minutes to three," he chattered.
"Hadn't you better go back and get your moccasins?" Frona asked. "There will be time."
"And miss the magnificence? Hark!"
From nowhere in particular a brisk crackling arose, then died away. The ice was in motion. Slowly, very slowly, it proceeded down stream. There was no commotion, no ear-splitting thunder, no splendid display of force; simply a silent flood of white, an orderly procession of tight-packed ice--packed so closely that not a drop of water was in evidence. It was there, somewhere, down underneath; but it had to be taken on faith. There was a dull hum or muffled grating, but so low in pitch that the ear strained to catch it.
"Ah!
