We shall in the next place give an astonishing instance of Sagacity in a Horse.
At Chepstow, in Monmouthshire there is a bridge, the construction of which is extremely curious, as the planks that form the floor rise with the tide, which, at certain times, is said to attain to the height of seventy feet.
This floor of the bridge it was necessary at one time to re-move; which was accordingly done, and only one or two of the planks remained for the convenience of the foot passengers. This way was well lighted, and a man placed at the end to warn those that approached of their danger. But it so happened, that one dreadful stormy night the lamps blew out, and the monitor, supposing that no one would in such a hurricane attempt to pass, wisely retired to shelter.
After midnight, a traveller knocked at the door of an inn at Chepstow.
"Who is there?" said the landlord, who had long retired to rest, and was now called out of bed.
The traveller mentioned his name, which was well known.
"How did you come?" said the landlord.
"How did I come ? Why, over the bridge to be sure!"
"What! on horseback ?"
"Yes."
"No !" said the landlord, "that is impossible ! however, as you are here, I'll let you in."
The host, when the traveller repeated his assertion, was staggered. He was certain that he must have come over the bridge, because there was no other way ; but also knowing the state in which the passage was, he could only attribute the escape of the traveller and his horse to witchcraft. He, however, said nothing to him that night; but the next morning took him to the bridge, and showed him the plank that his horse must have passed over, at the same time that he pointed to the raging torrent beneath.
Struck with this circumstance, the traveller, it is said, was seized with an illness from which he did not speedily recover.
