with the matted hair on the forehead, rendered it impervious to a
bullet.

When the bull was within a yard of him he leaped lightly to one side
and it passed. Just as it did so, Dick aimed at its heart and fired,

ball entered the shoulder too high, and the bull, checking himself as

The failure, coupled with the excitement, proved too much for Dick; he

shaggy front, and with a hideous bellow thundered forward. Again Dick
sprang to one side, but in doing so a tuft of grass or a stone caught
his foot, and he fell heavily to the ground.

Up to this point Crusoe's admirable training had nailed him to the
spot where he had been left, although the twitching of every fibre in
his body and a low continuous whine showed how gladly he would have
