hungry animals waiting to attack

hungry animals waiting to attack Buck sat by the fire with this Concrete Mixer hairy man， and in the circling darkness beyond the fire he could see many eyes—the eyes of hungry animals waiting to attack． And he growled softly in his dream until the Indian cook shouted，‘Hey， Buck， wake up！’Then the strange world disappeared and Buck's eyes saw the real fire again．

When they reached Dawson， the dogs were tired， and needed a week's rest But in two days they were moving south again， with another heavy load of letters． Both dogs and men were unhappy． It snowed every day as well， and on soft new snow it was harder work pulling the sledges．

The men took good care of their dogs．In the evenings， the dogs ate first，the men second，and they always checked the dogs’ feet before they slept． But every day the dogs became weaker．Buck had pulled sledges for three thousand kilometres that winter， and he was as tired as the others．
