stepping softly and silently
They saw him walking out of camp but they didn't see
canvas bag the change that happened when he was inside the forest．At once he became a thing of the wild，stepping softly and silently，a passing shadow among the trees．
In the autumn，Buck started to see moose in the forest．One day he met a group of about twenty．The largest was two me tres tall，and his antlers were more than two metres across．When he saw Buck， he got very angry． For hours Buck fol lowed the moose；he wanted the big one，but he wanted him alone．By the evening Buck had driven the big old moose away from the others，and then he began his attack．The animal weighed six hundred and fifty kilos—he was big enough and strong enough to kill Buck in seconds．Patiently，Buck fol lowed him for four days，attacking and then jumping away．He gave him no peace，no time to eat or drink or rest， and slowly the moose became weaker．At the end of the fourth day Buck pulled the moose down and killed him．He stayed by the dead animal for a day and a half，eating，and then turned towards camp and John Thornton．
Five kilometres from the camp，he smelt something strange．Something was wrong．He started to run．After a few hundred metres he found the dead body
canvas bag of Blackie，with an arrow through his side．Then he found another sledge－dog，dying，with an arrow in his neck．
