And M. Aubry-Pasteur, always puffing, stopped on his way back from his daily walk. Then Andermatt explained his experiment in curing. But the old man kept repeating: "Devil take it! how hot it is!" And he wanted to get out, asking some one to help him up. The banker succeeded eventually in calming him by promising him twenty sous more for each bath. The spectators formed a circle round the hole, in which the dirty, grayish rags were soaking wherewith this old body was covered.
A voice said: "Nice meat for broth! I wouldn't care to make soup of it!"
Another rejoined: "The meat would scarcely agree with me!"
But the Marquis observed that the bubbles of carbonic acid seemed more numerous, larger, and brighter in this new spring than in that of the baths.
The vagabond's rags were covered with them; and these bubbles rose to the surface in such abundance that the water appeared to be crossed by innumerable little chains, by an infinity of beads of exceedingly small, round diamonds, the strong midday sun making them as clear as brilliants.
Then Aubry-Pasteur burst out laughing: "Egad," said he, "I must tell you what they do at the establishment. You know they catch a spring like a bird in a kind of snare, or rather in a bell. That's what they call coaxing it. Now last year here is what happened to the spring that supplies the baths. The carbonic acid, lighter than water, was stored up to the top of the bell; then, when it was collected there in a very large quantity, it was driven back into the ducts, reascended in abundance into the baths, filled up the compartments, and all but suffocated the invalids. We have had three accidents in the course of three months. Then they consulted me again, and I invented a very simple apparatus consisting of two pipes which led off separately the liquid and the gas in the bell in order to combine them afresh immediately under the bath, and thus to reconstitute the water in its normal state while avoiding the dangerous excess of carbonic acid. But my apparatus would have cost a thousand francs. Do you know what the custodian does then? I give you a thousand guesses to find out. He bores a hole in the bell to get rid of the gas, which flies out, you understand, so that they sell you acidulated baths without any acid, or so little acid that it is not worth much. Whereas here, why just look!"
Everybody became indignant. They no longer laughed, and they cast envious looks toward the paralytic. Every bather would gladly have seized a pickax to make another hole beside that of the vagabond. But Andermatt took the engineer's arm, and they went off chatting together. From time to time Aubry-Pasteur stopped, made a show of drawing lines with his walking-stick, indicating certain points, and the banker wrote down notes in a memorandum-book.
Christiane and Paul Bretigny entered into conversation. He told her about his journey to Auvergne, and all that he had seen and experienced. He loved the country, with those warm instincts of his, with which always mingled an element of animality. He had a sensual love of nature because it excited his blood, and made his nerves and organs quiver. He said: "For my part, Madame, it seems to me as if I were open, so that everything enters into me, everything passes through me, makes me weep or gnash my teeth. Look here! when I cast a glance at that hillside facing us, that vast expanse of green, that race of trees clambering up the mountain, I feel the entire wood in my eyes; it penetrates me, takes possession of me, runs through my whole frame; and it seems to me also that I am devouring it, that it fills my being—I become a wood myself!"
He laughed, while he told her this, strained his big, round eyes, now on the wood, now on Christiane; and she, surprised, astonished, but easily impressed, felt herself devoured also, like the wood, by his great avid glance.
Paul went on: "And if you only knew what delights I owe to my sense of smell. I drink in this air through my nostrils. I become intoxicated with it; I live in it, and I feel that there is within it everything—absolutely everything. What can be sweeter? It intoxicates one more than wine; wine intoxicates the mind, but perfume intoxicates the imagination. With perfume you taste the very essence, the pure essence of things and of the universe—you taste the flowers, the trees, the grass of the fields; you can even distinguish the soul of the dwellings of olden days which sleep in the old furniture, the old carpets, the old curtains. Listen! I am going to tell you something.
