"We have been discussing the length of a journey to the Geysers of Iceland, also to the hot springs of the Yellowstone, but I am afraid either would require too much time. Was your bath agreeable?" "Very," said Leo, describing how he had been pummelled. "Those were the fellows from the steam-rooms--stokers probably. Rough enough they are. Do you care to have a glance at them at work?" "Don't care if I do," said Leo, in his old drawling manner; then, correcting himself, he added: "If it suits your convenience, I shall be very happy to take a look." "That is all it will be, I promise you," said Paz; "the heat is awful." Leo thought as much when Knops, having tied a respirator over his mouth, opened another door. Such a cloud of vapor puffed out that he could but dimly discern what seemed to be a tank of boiling, bubbling water, resting on a bed of soft coal, about which stark little forms were dancing and poking with long steel bars until flames leaped out like tongues of fire. "Oh," said Leo, as he quickly turned from his place, "how do they endure it? It is dreadful!" "They are used to it; they all came from Terra del Fuego," replied Knops, calmly. "And now, as a contrast to them, look in here." A hut of solid ice presented itself. Long pendants of ice hung from the ceiling, snow in masses was being formed into shapes of statue-like grace by a company of little furry objects whose noses were not even visible, and others were tracing out, on a broad screen of lace-like texture, patterns of every star and leaf and flower imaginable. Leo was so delighted that, although shivering, he could not bear to leave them, but begged Knops to lend him a wrap. Taking from a pile of furs in a corner several small garments, Paz pinned them together and threw them over Leo's shoulders, and as he continued to watch the beautiful work Knops explained its character.
