On the day when he succeeded in extracting five distinct substances from his crude liquor, the room rang with cries of triumph. They had obtained quite a surprising proportion of bromide of potassium, and would be able to supply that popular remedy as plentifully as bread. Pauline danced wildly round the table; and then flew downstairs and burst into the dining-room, where her uncle was reading his newspaper and her aunt was marking table-napkins. 'There!' she cried, 'you can be as ill as you like now, and we can give you as much bromide of potassium as ever you'll want!' Madame Chanteau, who had been suffering lately from nervous attacks, had been put upon a bromide _régime_ by Doctor Cazenove. She smiled as she answered: 'Have you got enough to cure everyone?--for everyone seems to be out of sorts just now.' The vigorous young girl, whose face beamed with robust health, spread out her arms as though she were casting the remedy to the four corners of the earth. 'Yes, yes!' said she, 'we shall make enough for the whole world. Neurosis is done for!' After inspecting the coast Lazare decided that he would build his works near the Golden Bay. It answered all the necessary requirements. It had a wide spreading beach, flagged as it were with flat rocks, which facilitated the gathering of the weed; there was good communication from it by the Verchemont Road; land was cheap; the necessary materials were at hand; and it was sufficiently isolated without being remote. Pauline joked about the name which they had given to the bay on account of its gleaming sand. They did not think then, said she, that they would ever find real gold there, as they were going to do now. They made a capital beginning, bought about five acres of barren land at a low price, and obtained the Prefect's authorisation after only two months' delay. Then the building was commenced. Boutigny had already arrived on the scene. He was a little, ruddy-faced man of thirty, extremely common in appearance, and the Chanteaus did not take to him at all. He declined to live at Bonneville, saying that he had found a very convenient house at Verchemont; and the family's coldness towards him increased when they heard that he had brought there a woman whom he had probably picked up in some low haunt in Paris. Lazare shrugged his shoulders at what he called their provincial narrow-mindedness. She was a very pleasant sort of person, he thought, and had shown a good deal of devotion in consenting to bury herself in such a wilderness; but he made no further protest, on Pauline's account. What was expected from Boutigny was active surveillance and intelligent organisation of the work, and in this respect he showed himself to be all that could be desired. He was never idle, and had a perfect genius for management; under his direction the building soon sprang up.
