Don't forget them.

You and Jimmy will likely overtake me.

Hurry along." "All right," answered Bobby.

"We'll catch you before you reach smooth ice." So Skipper Ed drove away with never a thought of catastrophe, and was quickly swallowed up by the thickening snow, while Bobby and Jimmy loaded the seals and the things from the _igloo_ upon the sledge, and, spurred by the rising wind and snow, hurried with all their might.
Already great seas were booming and breaking with a roar upon the ice, and as the boys turned the dogs back upon the trail they observed a waving motion of the ice beneath them, which was rapidly becoming more apparent.

At one moment the dogs would be hauling the sledge up an incline, and at the next moment the sledge would be coasting down another incline close upon the heels of the team, as the heaving ice assumed the motion of the seas which rolled beneath.
As they receded from the ice edge, however, this motion diminished, until finally it was hardly perceptible at all, and there seemed no further cause for alarm or great speed, and the dogs, which were weary with the two days' heavy hauling, were permitted to proceed at their own leisurely gait.
At length through the snow they saw Skipper Ed waiting for them, but when he was assured they were following he proceeded.
"_Ah!_" Bobby shouted to his dogs a moment later, bringing them suddenly to a stop.
