He seemed to have an idea that his personal liberty was being interfered with, and so he resisted everything done by Sam or the dog-drivers. When by main force he was placed in position and the traces were fastened he made most violent attempts to escape. He struggled first to one side and then to the other in his frantic efforts. Then he tried to crawl under and then over the dog in front of him. Failing in this, he suddenly sprang forward with such force that he managed to seize hold of the short, stumpy tail of the dog in front of him. This was an unfortunate move on his part, as the dogs that are accustomed to work together will readily fight for each other when one is in trouble.
