About every two miles along the way they found little huts or caves, partly dug in the mass of volcanic rubbish, and partly built up, with roofs to protect the interior from the rain. These were intended as refuges for the pilgrims for passing the night or resting during storms, and had no doubt been of great service to those who preceded them. At one of these they halted for luncheon, which they took from the pack of one of their bearers, and later on they halted at another to pass the night. It is considered too great a journey to be made in a single day, except by persons of unusual vigor and long accustomed to mountain-climbing. The customary plan is to pass a night on the mountain when little more than half way up, and then to finish the ascent, and make the whole of the descent on the second day. It was cold that night in the upper air, and there was a strong wind blowing that chilled our young friends to the bone. The sleeping accommodations were not of the best, as there were no beds, and they had nothing but the rugs and shawls they had brought along from the foot of the mountain. Fred asked if there was any danger of their being disturbed by tigers or snakes, and was speedily reassured by Frank, who thought that any well-educated beast or serpent would never undertake a pilgrimage to the top of Fusiyama; and if one should have strayed as far as their resting-place, he would be too much played out to attend to any business. But though large game did not abound, there was plenty of a smaller kind, as they found before they had been ten minutes in the huts. Previous visitors had left a large and well-selected assortment of fleas, for which they had no further use, and their activity indicated that they had been for some time without food. They made things lively for the strangers, and what with chilling winds, hard beds, cramped quarters, and the voracity of the permanent inhabitants of the place, there was little sleep in that hut during the time of their stay.
