GEOLOGY.-We spent the next day in examining the magnesian and calcareous rubblestone which appears to constitute strata resting against and upon the serpentine rock of Presque Isle. This rock is highly charged with what appears to be chromate of iron. We examined the bay behind this peninsula, which appears to be a harbor capable of admitting large vessels. We ascended a conical hill rising from the bay, which the Indians call Totosh, or Breast Mountain. Having been the first to ascend its apex, the party named it Schoolcraft's Mountain. Near and west of it, is a lower saddle-shaped mountain, called by the natives The Cradle Top. Granite Point exhibits trap dykes in syenite. The horizontal red sandstone, which forms the peninsula connecting this point with the main, rests against and upon portions of the granite, showing its subsidence from water at a period subsequent to the upheaval of the syenite and trap. This entire coast, reaching from Chocolate River to Huron Bay-a distance of some seventy miles-consists of granite hills, which, viewed from the top of the Totösh, has the rolling appearance of the sea in violent motion. Its chief value must result from its minerals, of which iron appears to constitute an important item.

We reached Huron River on the 4th of July about three o'clock in the afternoon, having come on with a fine wind. At this place we met Mr. Aitkin's brigade of boats, seven in number, with the year's hunts of the Fond du Lac department. I landed and wrote official notes to the Sault St. Marie and to Washington, acquainting the government with my progress, and giving intelligence of the state of the Indians.

TRADERS' BOATS.-Mr. Aitkin reports that a great number of the Indians died of starvation, at his distant posts, during the winter, owing to the failure of the wild rice. That he collected for his own use but eight bushels, instead of about as many hundreds. That he had visited Gov. Simpson at Pembina, and found the latter unwilling to make any arrangements on the subject of discontinuing the sale of whisky to the Indians. That I was expected by the Indians on the Upper Mississippi, in consequence of the messages sent in, last fall. That efforts continue to be made by the agent at St. Peters, to draw the Chippewas to that post, notwithstanding the bloodshed and evils resulting from such visits.

That a hard opposition in trade has been manifested by the Hudson's Bay Company. That they have given out medals to strengthen and increase their influence with our Indians. And that liquor is required to oppose them at Pembina, War Road, Rainy Lake, Vermilion Lake and Grand Portage.

DOG AND PORCUPINE.-While at Huron River, we saw a lost dog left ashore, who had been goaded by hunger to attack a porcupine. The quills of the latter were stuck thickly into the sides of the nose and head of the dog. Inflammation had taken place, rendering the poor beast an object of pity and disgust.

BURROWING BIRDS.-At Point Aux Beignes (Pancake Point) one of the men caught a kingfisher by clapping his hand over an orifice in the bank. He also took from its nest six eggs. The bank was perforated by numbers of these orifices. At this point we observed the provisions of our advance came, put in cache, to lighten it for the trip down the bay. Leaving Mr. G. Johnston and Mr. Melancthon Woolsey at this point to await the return of the canoe, I proceeded to Cascade, or, as it is generally called, Little Montreal River. Johnston and Woolsey came up during the night. Next morning an Indian came from a lodge, leading a young otter by a string. The animal played about gracefully, but we had no temptation to purchase him with our faces set to the wilderness. At the latter place, which is on a part of the Sandybay of Graybeast River, the trap formation, which is the copperbearing rock, is first seen. This rock, which forms the great peninsula of Kewywenon, rises into cliffs on this bay, which at the elevation called Mammels by the French, deserve the name of mountains. Portions of this rock, viewed in extenso, are overlaid by amygdaloid and rubblestone-the latter of which forms a remarkable edging to the formation, in some places, on the northwest shore, that makes a canal, as at the Little Marrias.

KEWEENA PENINSULA. We were six days in coasting around this peninsula, which is highly metalliferous. At some points we employed the blast, to ascertain the true character and contents of the soil. At others we went inland, and devoted the time in exploring its range and extent. We examined the outstanding isolated

vein of carbonate of copper, called Roche Vert by the French. In seeking for its connection on the main shore, I discovered the black oxide in the same vein. In the range of the greenstone about two leagues south of this point, a vein of native copper, with ores and veinstones, was observed, and specimens taken.

The N. W. coast of the peninsula is greatly serrated and broken, abounding in little bays and inlets, and giving proofs of the terrible action of the storms on this rugged shore.

Notes of these examinations and of a trip inland were made, which cannot here be referred to more particularly.

UNFLEDGED DUCKS.-The men had rare and very exciting sport, in coasting around the peninsula, in catching the young of the onzig-which is the sawbill. In the early part of the month of July, the wings of the young are not sufficiently developed to enable them to fly. They will run on the water, flapping their unfledged wings, with great speed, but the gay Frenchmen, shouting at the top of their lungs, would propel their canoes so as to overtake them whenever the little fugitives could not find some nook in the rock to hide in. They chased down one day thirteen in this way, which were found a most tender and delicate dish. The excitement in these chases was extreme. At the Grand Marrias (now near Fort Wilkins) we obtained from the shore of the inner bay, agates, stilbite, and smoky quartz, &c.

SINGULAR VIVACITY.-In going from this bay through a rockbound strait, the rain fell literally in sheets. There was no escape, and our only philosophy was to sit still and bear it. The shower was so great that it obscured objects at a short distance. All at once the men struck up a cheerful boat song, which they continued, paddling with renewed energy, till the shower abated. I believe no other people under the sun would have thought of such a resource.

TRAMP IN SEARCH OF THE PICTURESQUE.-The wind rising ahead, we took shelter in an inlet through the trap range, which we called Houghton's Cove. After taking a lunch and drying our things, it was proposed to visit a little lake, said to give origin to the stream falling into its head. The journey proved a toilsome one;

but, after passing through woods and defiles, we at length stood on a cliff which overlooked the object sought for-a pond covered with aquatic plants. Wherever we might have gone in search of the picturesque, this seemed the last place to find it. On again reaching the lake the wind was found less fierce, and we went on to Pine River, where we encamped on coarse, loose gravel.

SEARCH FOR NATIVE COPPER.-The next day the wind blew fiercely, and we could not travel. In consequence of reports from the Indians of a large mass of copper inland, I manned a light canoe, and, leaving the baggage and camp in charge of Lesart, went back to a small bay called Mushkeeg, and went inland under their guidance. We wandered many miles, always on the point of making the discovery, but never making it; and returned with our fatigue for our pains. It was seven o'clock in the evening before we returned to our camp-at eight the wind abated, and we embarked, and, after traveling diligently all night, reached the western terminus of the Keweena portage at two o'clock next morninghaving advanced in this time about twenty-four miles. Next day, July 10, the wind rose again violently ahead.

ISLE ROYAL DESCRIED.-In coming down the coast of the Keweena Peninsula, we descried the peaks of this island seen dimly in the distance, which it is not probable could have been done if the distance were over sixty miles.

INDIAN PRECAUTION, THEIR INGENUITY.-We found several Chippewa Indians encamped. They brought a trout, the large lake trout, and were, as usual, very friendly. We saw a fresh beaver's skin stretched on the drying hoop, at the Buffalo's son's lodge. But the women had secreted themselves and children in the woods, with the dried skins, supposing that a trader's canoe had landed, as we had landed in the night. This may give some idea of the demands of trade that are usually made, and the caution that is observed by them when a trader lands.

We here saw the claws of two owls, with the skin and leg feathers adhering, sewed together so closely and skilfully, by the Indian women, as to resemble a nondescript with eight claws. It was only by a close inspection that we could discover the joinings.

LAKE ACTION.-The geological action of the lake against the high banks of diluvion, at this spot, is very striking. It has torn away nearly all the ancient encamping ground, including the Indian burials. Human bones were found scattered along the declivity of fallen earth. An entire skull was picked up, with the bark wrappings of the body, tibia, &c.

At seven in the evening the tempest ceased so as to enable us to embark. We kept close in shore, as the wind was off land, a common occurrence on these lakes at night. On turning the point of red sandstone rock, which the Indians call Pug-ge-do-wau (Portage), the Porcupine Mountains rose to our view, directly west, presenting an azure outline of very striking lineaments—an animal couchant. As night drew on, the water became constantly smoother; it was nine before daylight could be said to leave us. We passed, in rapid succession, the Mauzhe-ma-gwoos or Trout, Graverod's, Unnebish, or Elm, and Pug-ge-do-wa, or Misery River, in Fishing Bay. Here we overtook Lieut. Clary, and encamped at one o'clock A. M. (11th). We were on the lake again at five o'clock. We turned point a la Peche, and stopped at River Nebau-gum-o-win for breakfast. While thus engaged, the wind rose and shifted ahead. This confined us to the spot.

NEBAUGUMOWIN RIVER.-Mr. Johnston, Dr. Houghton, and Mr. Woolsey, made an excursion in a canoe up the river. They went about three or four miles-found the water deep, and the banks high and dry on the right side (going up), and covered with maple, ash, birch, &c. At that distance the stream was obstructed by logs, but the depth of water continued. Dr. H. added to his botanical collection. Altogether appearances are represented more favorable than would be inferred from the sandy and swampy character of the land about its discharge into the lake.

EAGLES.-While at the Mauzhe-ma-gwoos River, Lieut. Clary captured a couple of young eagles, by letting his men cut down a large pine. One of the birds had a wing broken in falling. They were of the bald-headed kind, to which the Chippewas apply the term Megizzi, or barker. He also got a young mink from an Indian called Wabeno. The men also caught some trout in that river, for which it is remarkable.

At two o'clock the wind had somewhat abated, so as to allow us to
