There was, too, one “Maistre François Choisnyn,” physician to the queen of Navarre, a special favourite with Bernard, of whom he says—“His company and visits were a source of great consolation to me.” These two went a little geological exploration together, in the year 1575. “He had heard me often speak,” said Palissy, “of these matters, and knowing that he was a lover of the same, I begged him to accompany me to the quarries, near St. Marceau, that I might give him ocular proof of what I had said concerning petrifactions; and he, full of zeal in the affair, immediately caused waxen flambeaux to be brought, and taking with him his medical pupil, named Milon, [152] we went to a place in the said quarries, conducted by two quarrymen; and there we saw what I had long before known, from the form of stones shaped like icicles, having seen a number of such stones, which had been brought, by command of the queen mother, from Marseilles; also among the rocks on the shores of the river Loire. Now, in those quarries we saw the distilled water congeal in our presence, which set the matter at rest.” Another day, walking with his friend, he found himself, while wandering over the fields, very thirsty, and passing by some village, asked where he could meet with a good spring, in order to refresh himself; but he was told there was no spring in that place, all their wells being exhausted on account of the drought, and that there was nothing but a little muddy water left in them. This caused him “much vexation,” and expressing his surprise at the distress suffered by the inhabitants of that village through want of water, he proceeded to explain to his companion his theory on springs, in which he propounded a doctrine which the science of the present day has pronounced absolutely correct. [153]

This subject led Bernard to recur to the home of his early manhood, and he added, “At Saintes, which is a very ancient town, there are still found the remains of an aqueduct, by which, formerly, they caused the water to come from a distance of two great leagues. There are now no ancient fountains; by which I do not mean to say we have lost the water-courses, for it is well known that the ancient spring of the town of Saintes is still on the spot where it formerly existed; to see which, the chancellor De l’Hôpital, travelling from Bayonne, turned out of his way to admire the excellence of the said spring. Now, in the neighbourhood of Saintes, is a small town called Brouage, situated on the coast amongst the marshes of Saintonge. Its name points out its nature, the word ‘brou,’ meaning, marshy soil. That said town has undergone two sieges during the civil wars; the last in the year 1570. When besieged, it suffered much from want of water, and I am, at the present time, preparing an advertisement to the governor and inhabitants thereof, to explain to them that the situation of the place is very commodious for making a fountain there, at small expense.”

“Your mention of this reminds me,” said his companion, “of the remarkable manner in which the city of Nismes fell into the hands of the Huguenots, some four or five winters ago.”

Palissy expressed a wish to hear the particulars, with which he was but imperfectly acquainted; and as the story affords a striking instance of the spirit which animated even obscure individuals in the cause of religion and freedom, it shall be told here.

The governor of Nismes, a ferocious old man, had treated the Huguenots with the utmost barbarity, and had plundered and banished great numbers of them, who had retired to a neighbouring town. Among those left in Nismes was a carpenter, named Maderon, who resolved to deliver the town into the hands of his exiled brethren, and for that purpose took advantage of the famous fountain, the abundant waters of which flowed between the gate of Carmes and the castle, through a channel which was closed by a grate. Just above, and close by the castle, a sentinel was placed, who was relieved every hour. When he was about to leave he was accustomed to ring a bell, in order to advertise the soldier who was to relieve him, to come and take his place. A short interval always elapsed between the departure of one soldier and the arrival of the other, and Maderon having observed this, undertook, in those moments, to file asunder the bars of the grate.

He executed his purpose thus. In the evening he went down into the ditch, with a cord fastened round his body, the end of which was pulled by a friend when the soldier quitted his post, and again, when the other arrived. Maderon worked during these few moments, and then ceasing, waited in patience till another hour elapsed. In the morning he covered his work with mud and wax. In this manner did this indefatigable man work for fifteen nights, the noise he made being drowned by the rushing of the waters. It was not till his work was nearly completed that he informed the exiles of his success, and invited them to take possession of the town. They appear to have wanted courage for the undertaking; and while irresolute, a flash of lightning, though the weather was otherwise serene, terrified and put them to flight; but their minister, pulling them by their sleeves, exhorted them to come back, saying, “Courage! this lightning shows that God is with us.”

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.”

But, like a true philosopher, he was anxious, first, to subject his theories to the test of keen criticism. Free discussion was, he knew, the best friend to the true interests of science, and he resolved, therefore to invite about him the most learned persons then resident in the capital, and to meet them in his lecture room to state to them his opinions, and to hear their arguments in reply. He set about doing this in a peculiar manner, which he describes. “Thus debating in my mind, I decided to cause notices to be affixed to the street corners in Paris, in order to assemble the most learned doctors, and others, to whom I would promise to demonstrate, in three lessons, all I have learned concerning fountains, stones, metals, and other natures. And, in order that none might come but the most learned and curious, I put in my placards that none should have admission without payment of a dollar. I did this partly to see whether I could extract from my hearers some contradiction which might have more assurance of truth than the arguments I should propound; knowing well that, if I spoke falsely, there would be Greeks and Latins who would resist me to my face, and who would not spare me, as well on account of the dollar I should have taken from each, as on account of the time I should have caused them to misspend. For there were very few of my hearers who could not elsewhere have extracted profit out of something during the time spent by them at my lessons. Also, I put in my placards that if the things therein promised did not prove trustworthy, I would restore the quadruple.”

The result of this experimental course was most successful. “Thanks be to God,” says the triumphant lecturer, “never man contradicted me a single word.”
