All this took a long time, and Palissy gave up his surveying in order to devote his whole days to this labour of love. The reward, however, was very slow in coming, and if he had not contrived to save a little money while he was still a bachelor his wife and children would have starved. Week after week went by, and Palissy was to be seen in his little workshop, making experiments with pieces of common pots, over which he spread the different mixtures he had made. These pieces, he tells us, 'he baked in his furnace, hoping that some of these mixtures might, when hot, produce a colour'; white was, however, what he desired above all, as he had heard that if once you had been able to procure a fine white, it was comparatively easy to get the rest. Remembering how as a boy he had used certain chemical substances in staining the glass, he put these into some of his mixtures, and hopefully awaited the result. But, alas! he 'had never seen earth baked,' and had no idea how hot the fire of his furnace should be, or in what way to regulate it. Sometimes the substance was baked too much, and sometimes too little; and every day he was building fresh furnaces in place of the old ones which had cracked, collecting fresh materials, making fresh failures, and altogether wasting a great deal of time and money. * * * * * Thus passed several years, and it is a marvel how the family contrived to live at all, and madame Palissy had reason for the reproaches and hard words which she heaped on her husband. The amount of wood alone necessary to feed the furnaces was enormous, and when Palissy could no longer afford to buy it, he cut down all the trees and bushes in his garden, and when they were exhausted burned all the tables and chairs in the house and tore up the floors. Fancy poor madame Palissy's feelings one morning when this sight met her eyes. His friends laughed at him and told tales of his folly in the neighbouring town, which hurt his feelings; but nothing turned him from his purpose, and except for the few hours a week when he worked at something which _would_ bring in money enough to keep his family alive, every moment, as well as every thought, was given up to the discovery which was so slow in being made.
