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 take the lake, and we reached and entered the Ontonagon River at half past four o'clock. Mr. Johnston with the store canoe, and Lieut. Clary with his boat, came in successively with colors flying. Kon-te-ka, the chief, and his band saluted us with several rounds of musketry from the opposite shore. Afterwards they crossed to our camp, and the usual exchange of ceremonies and civilities took place. In a speech from the chief he complained much of hunger, and presented his band as objects of charitable notice. I explained to him the pacific object of my journey, and the route to be pursued, and requested the efficient co-operation of himself and his band in putting a stop to war parties, referring particularly to that by Kewaynokwut in 1824, which, although raised against the Sioux, had murdered Finley and his men at Lake Pepin. This party was raised on the sources of the Ontonagon and Chippewa. I told him how impossible it was that his Great Father should ever see their faces in peace while they countenance or connive at such dastardly war parties, who went in quest of a foe, and not finding him, fell upon a friend. He said he had not forgotten this. Even now, I continued, a chief of the Sauks was trying to enlist the Indians in a scheme of extreme hostilities. It was a delusion. They had no British allies to rally on as in former wars. The time was past--past forever for such plans. We are in profound peace. And their Great Father, the President, would, if the scheme was pursued by that chief, order his whole army to crush him. I requested him to inform me of any messages, or tobacco, or wampum they might receive, on the subject of that chief's movement, or any other government matter. And to send no answer to any such message without giving me notice.

At three o'clock on the morning of the next day (12th July), Dr. Houghton, Mr. Johnston, Lieut. Clary, and Mr. Woolsey, with nine Canadians and one soldier, set out in my canoe to visit the copper rock. Konteka sent me a fine carp in the morning. Afterwards he and the other chief come over to visit me. The chief said that his child, who had been very ill, was better, and asked me for some white rice (waube monomin) for it, which I gave. I also directed a dish of flour and other provisions to enable him to have a feast.

INDIAN TOMB.--One of the Indians had a son drowned a few days before our arrival; the grave was neatly picketed in. On the west side of the river is a grave or tomb above ground, resembling a lodge, containing the coffin of a chief, who desired to be thus buried, as he believed his spirit would go directly up.
