describe how hal tried to resolve the fact that he had miscalculated the amount of dog food required for the trip.

Hal tried to resolve his miscalculation of food by first overfeeding the dogs, and then underfeeding them.

It was inevitable that they should go short on dog-food. But they hastened it by overfeeding, bringing the day nearer when underfeeding would commence. The Outside dogs, whose digestions had not been trained by chronic famine to make the most of little, had voracious appetites. And when, in addition to this, the worn- out huskies pulled weakly, Hal decided that the orthodox ration was too small. He doubled it. And to cap it all, when Mercedes, with tears in her pretty eyes and a quaver in her throat, could not cajole him into giving the dogs still more, she stole from the fish-sacks and fed them slyly. But it was not food that Buck and the huskies needed, but rest. And though they were making poor time, the heavy load they dragged sapped their strength severely.

Then came the underfeeding. Hal awoke one day to the fact that his dog-food was half gone and the distance only quarter covered; further, that for love or money no additional dog-food was to be obtained. So he cut down even the orthodox ration and tried to increase the day’s travel.
