We shouted, expecting that they would reply, and that we should be guided by their voices, but no sound came in return.  We tried to run on, hoping to overtake them, when Hugh fell and broke one of his snow-shoes.  We, of course, stopped to help him up, and in so doing must have turned slightly about.  Red Squirrel, ever fertile in resources, set to work to mend the shoe.  This he did very rapidly; but even that short delay was serious.  As soon as Hugh was on his legs we again hurried on, supposing that we were following close behind the rest of the party.  We shouted and shouted, but still there was no reply.  I asked Red Squirrel if he thought we were going right.
