Notwithstanding our precaution to make signals, one of my scouts happened one day to stray, because the weather was foggy; so that he did not return at night to our hut; at which I was very uneasy, and could not sleep; as he was not returned, though the signals of call had been repeated till night closed. About nine the next morning he cast up, telling us he had been in pursuit of a drove of deer, which were led by one that was altogether white: but that not being able to come up with them, he picked up, on the side of a hill, some small sharp stones, of which he brought a sample.
These stones I received with pleasure, because I had not yet seen any in all this country, only a hard red free-stone in a cliff on the Missisippi. After carefully examining those which my discoverer brought me, I found they were a gypsum. I took home some pieces, and on my return examined them more attentively; found them to be very clear, transparent, and friable; when calcined, they turned extremely white, and with them I made some factitious marble. This gave me hopes that this country, producing Plaster of Paris, might, besides, have stones for building.
I wanted to see the spot myself: we set out about noon, and travelled for about three leagues before we came to it. I examined the spot, which to me appeared to be a large quarry of Plaster.
As to the white deer above mentioned, I learned from the Indians, that some such were to be met with, though but rarely, and that only in countries not frequented by the hunters.
The wind being set in for rain, we resolved to put ourselves under shelter. The place where the bad weather overtook us was very fit to set up at. On going out to hunt, we discovered at five hundred paces off, in the defile, or narrow pass, a brook of a very clear water, a very commodious watering-place for the buffaloes, which were in great numbers all around us.
My companions soon raised a cabin, well-secured to the North. As we resolved to continue there for eight days at least, they made it so close as to keep out the cold: in the night, I felt nothing of the severity of the North wind, though I lay but lightly covered. My bed consisted of a bear's skin, and two robes or coats of buffalo; the bear skin, with the flesh side undermost, being laid on leaves, and the pile uppermost by way of straw-bed; one of the buffalo coats folded double by way of feather-bed; one half of the other under me served for a matrass, and the other over me for a coverlet: three canes, or boughs, bent to a semicircle, one at the head, another in the middle, and a third at the feet, supported a cloth which formed my tester and curtains, and secured me from the injuries of the air, and the stings of gnats and moskitto's. My Indians had their ordinary hunting and travelling beds, which consist of a deer skin and a buffalo coat, which they always carry with them, when they expect to lie out of their villages. We rested nine days, and regaled ourselves with choice buffalo, turkey, partridge, pheasants, &c.
The discovery I had made of the plaster, put me to look out, during our stay, in all the places round about, for many leagues. I was at last tired of beating about such fine plains, without discovering the least thing, and I had resolved to go forward to the North when at the noon-signal the scout a-head waited to shew me a shining and sharp stone, of the length and size of one's thumb, and as square as a joiner could have made a piece of wood of the same bigness. I imagined it might be rock-crystal; to be assured thereof, I took a large musquet flint in my left hand, presenting its head, or thick end, on which I struck with one of the edges of the crystal, and drew much more fire than with the finest steel: and notwithstanding the many strokes I gave, the piece of crystal was not in the least scratched or streaked.
I examined these stones, and found pieces of different magnitudes, some square, others with six faces, even and smooth like mirrors, highly transparent, without any veins or spots. Some of these pieces jutted out of the earth, like ends of beams, two feet and upwards in length; others in considerable numbers, from seven to nine inches; above all, those with six panes or faces. There was a great number of a middling and smaller sort: my people wanted to carry some with them; but I dissuaded them. My reason was, I apprehended some Frenchman might by presents prevail on them to discover the place.
For my part, I carefully observed the latitude, and followed, on setting out, a particular point of the compass, to come to a river which I knew. I took that route, under pretense of going to a certain nation to procure dry provisions, which we were in want of, and which are of great help on a journey.
We arrived, after seven days march, at that nation, by whom we were well received. My hunters brought in daily many duck and teal. I agreed with the natives of the place for a large pettyaugre of black walnut, to go down the river, and afterwards to go up the Missisippi.
