Nic was following too, with the sensation strongly upon him that he should like to go down on all-fours and follow like a dog, for walking seemed to be a mode of progress to which he was not accustomed.

They must want water too." Nic went to where the dogs were chained to the tail of the waggon, trying to walk firmly and erect, but it was hard work, for his legs seemed to be independent of his body, and there were moments when he felt as if he had none at all.

The task was not so easy as it looked, for the collies were frantic at the thought of being unfastened, and barked and leaped about wildly.
