The shinansha, of the South pointing carriage
After a long time he invented the shinansha with the figure of a man always pointing South, for there were no compasses in those days. With this instrument to show him the way he need not fear the dense fogs raised up by the magician to confound his men.
Kotei again declared war against Shiyu. He placed the shinansha in front of his army and led the way to the battlefield.
The battle began in earnest. The rebel was being driven backward by the royal troops when he again resorted to magic, and upon his saying some strange words in a loud voice, immediately a dense fog came down upon the battlefield.
But this time no soldier minded the fog, not one was confused. Kotei by pointing to the shinansha could find his way and directed the army without a single mistake. He closely pursued the rebel army and drove them backward till they came to a big river. This river Kotei and his men found was swollen by the floods and impossible to cross.
Shiyu by using his magic art quickly passed over with his army and shut himself up in a fortress on the opposite bank.
When Kotei found his march checked he was wild with disappointment, for he had very nearly overtaken the rebel when the river stopped him.
He could do nothing, for there were no boats in those days, so the Emperor ordered his tent to be pitched in the pleasantest spot that the place afforded.
One day he stepped forth from his tent and after walking about for a short time he came to a pond. Here he sat down on the bank and was lost in thought.
It was autumn. The trees growing along the edge of the water were shedding their leaves, which floated hither and thither on the surface of the pond. By and by, Kotei's attention was attracted to a spider on the brink of the water. The little insect was trying to get on to one of the floating leaves near by. It did so at last, and was soon floating over the water to the other side of the pond.
This little incident made the clever Emperor think that he might try to make something that could carry himself and his men over the river in the same way that the leaf had carried over the spider.
