Twenty of them entered the town, and being joined by others who were exasperated at the cruelty of the governor, it was taken, and the castle surrendered a few days after. “That was truly an admirable occurrence,” said Bernard. “And the results were very important, since the town, by the large supplies it afforded, was of great service to the army of the princes during the ensuing spring.” “There will doubtless be many historians who will employ themselves upon these matters,” said Palissy; “and the better to describe the truth, I should think it wise that in each town there should be persons deputed to write faithfully the things that have been done during these troubles. I have myself already given a short narrative of what befell when I was resident in Saintonge, and I have left others to write of those things which themselves have witnessed. At present I am engaged in preparing a volume of Discourses on Natural Objects, of practical use to agriculturists and others, and I purpose, in the Lectures I have just commenced, to discuss various positions with reference to these matters, to which end, as you know, I have invited interruption, contradiction, and discussion, from those who may attend them.” Palissy referred, in these words, to an undertaking which we find he commenced in the Lent of the year 1575, and which he carried on, for several seasons, annually. “Considering,” he says, “that I had employed much time in the study of earths, stones, waters, and metals, and that old age pressed me to multiply the talents which God had given me, I thought good to bring forward to light those excellent secrets, in order to bequeath them to posterity.”
