Before reaching Hakone it was necessary to traverse a mountain pass, by ascending a very steep road to the summit and then descending another. In the wildest part of the mountains they came to a little village, which has a considerable fame for its hot springs. The boys had a fancy to bathe in these springs, and, as the coolies needed a little rest after their toilsome walk, it was agreed to halt awhile. There were several of the springs, and the water was gathered in pools, which had a very inviting appearance and increased the desire of our friends to try them. They went into one of the small rooms provided for the purpose, removed their clothing, and then plunged in simultaneously. They came out instantly, and without any request to do so by the Doctor, who stood laughing at the edge of the pool. For their skins the water was almost scalding-hot, though it was far otherwise to the Japanese. The Japanese are very fond of hot baths, and will bathe in water of a temperature so high that a foreigner cannot endure it except after long practice. The baths here in the mountains were just suited to the native taste; and Frank said they would be suited to his taste as well if they could have a few blocks of ice thrown into them. [Illustration: A JAPANESE BATH.] Public and private baths are probably more numerous in Japan than in any other country. The qualities of most of the natural sources are well known, and thousands flock to them every year to be cured of real or imaginary maladies. The country contains a great number of these springs; and, since the arrival of foreigners, and a careful analysis of the waters, certain properties have been discovered that were not known before. In some cases the curative powers of the Japanese springs are remarkable, and it has been predicted that patients will one day come to Japan from distant lands to be healed. [Illustration: THE LAKE OF HAKONE.] The Lake of Hakone is a beautiful sheet of water, not unlike Lake Tahoe in California--an aquatic gem in a setting of rugged mountains. These are not lofty, like the mountains of the Golden State, so far as their elevation above the lake is concerned; but they rise directly from the water, and present nearly everywhere a bold frontage. The surface of the lake is said to be more than six thousand feet above the level of the sea; and the water is clear and cold. Our young friends tried a bath in the lake, and found it as inconveniently cold as the springs had been inconveniently warm. "Some people are never satisfied," said Fred, when Frank was complaining about the temperature of the water in the lake. "You wouldn't be contented with the springs because they boiled you, and now you say the lake freezes you. Perhaps we'll find something by-and-by that will come to the point."
