A short rest was taken, then, with renewed strength, the pursuit was continued. At the end of an hour a lake was sighted some distance ahead. It was a large body of water, evidently grandly situated in a basin formed by three hills and a lofty mountain. Pointing to the latter, which reared its conical head twelve thousand feet above the level of the lake, Mori said, impressively:
"The volcano of Bandai-San."
"And at its base are the caves?" eagerly asked Nattie.
"Yes, the mud caves where we hope Ralph and Mr. Round have taken their prisoner."
"What is that on the edge of the lake? It seems to be a ruin."
"That's the shiro, or old castle of Yamagata. By Jove! I had forgotten that it was here. It is a feudal pile, and has a quaint history. I will tell you something of it as we ride along. The road passes the entrance."
Bidding the karumayas run together, Mori continued:
"It was a stronghold of an ancient daimio, or prince. He ruled the country around here for many years. He was very wealthy, and spent an immense sum of money on the castle. You can see by its extent and the material that it cost no small amount. The walls are of stone, some of the blocks being forty feet long by ten feet in width, and many have a thickness of an English yard.
"Those two lofty towers were once surmounted with huge fish made of copper, and covered with plates of gold. You can imagine the temptation to the peasants. One windy night a robber mounted an immense kite and tried to fly to the top of the first tower for the purpose of stealing the golden scales, but he was caught and boiled alive in oil."
