At another time, the Eschevin hurls his anathema at the system of warming by steam. According to him, this diabolical invention is an incessant cause of damp to the wood-work, the furniture, the papers, and the books. The Eschevin fancies, in short, that in this way of warming, torrents of watery vapour enter into the atmosphere of the apartments. Can he love a colleague, I ask, who after having had the cunning patience to let him come to the conclusion of his discourse, informs him that, although vapour, the vehicle of an enormous quantity of latent heat, rapidly conveys this caloric to every floor of the largest edifice, it has never occasion therefore to escape from those impermeable tubes through which the circulation is effected! Amidst the various labours that are required by every large town, the Eschevin thinks, some one day, that he has discovered an infallible way of revenging himself of specialties. Guided by the light of modern geology, it has been proposed to go with an immense sounding line in hand, to seek in the bowels of the earth the incalculable quantities of water, that from all eternity circulate there without benefiting human nature, to make them spout up to the surface, to distribute them in various directions, in large cities, until then parched, to take advantage of their high temperature, to warm economically the magnificent conservatories of the public gardens, the halls of refuge, the wards of the sick in hospitals, the cells of madmen. But according to the old geology of the Eschevin, promulgated perhaps by his nurse, there is no circulation in subterranean water; at all events, subterranean water cannot be submitted to an ascending force and rise to the surface; its temperature would not differ from that of common well-water. The Eschevin, however, agrees to the expensive works proposed. Those works, he says, will afford no material result; but once for all, such fantastic projects will receive a solemn and rough contradiction, and we shall then be liberated for ever from the odious yoke under which science wants to enslave us. However, the subterranean water appears. It is true that a clever engineer had to bore down 548 metres (or 600 yards) to find it; but thence it comes transparent as crystal, pure as if the product of distillation, warmed as physical laws had shown that it would be, more abundant indeed than they had dared to foresee, it shot up thirty-three metres above the ground.
