run the faster. But Marco was not very easily frightened; at least,
he was not easily made crazy by fright. So he did not scream; and not
knowing what else to do, he sat still and did nothing.

In the mean time, the passengers inside knew nothing of all this. Many
of them had been asleep when they came over the bridge. The jolt had
aroused them a little, but there was nothing to indicate to them

The horses were well trained and gentle. They cantered on as far as

they began to rise the ascent. The idea then occurred to Marco, that
perhaps he might clamber down over the fender to the pole, and then
walk along upon that a little way till he could gather up the reins.
Then he thought that if he could get back again with them to the
