The next morning (20th), a heavy fog in the Fox Valley detained us in our encampment till 7 o'clock. Six miles brought us to another rapid, called the Little Kakala, which, however, opposes no obstacle to the descent of canoes. At this spot, which is the apparent western terminus of the Bay settlement, we found a party of U. S. soldiers, from Fort Howard, engaged in digging the foundations for a saw-mill. Our appearance must have been somewhat rusty at this time, from our deficiences in the tonsorial and sempstrescal way, for these sons of Mars did not recognize their superior officers in Capt. Douglass and Lt. Mackay; glibly saying, in a jolly way, as they handed them a drink of water: "After me, sir, is manners;" and drinking off the first cup. At this rapid I got out of my canoe, wishing to see the geological formation more fully, and walked quite to the Rapide du Pere, where Fox River finds its level in the broad, elongated, and lake-like tongue of water, extending up from the head of Green Bay. On reaching this point, the scene of the settlement first burst on our view, with its farm-houses and cultivated fields stretching, for five miles, along both banks of the river; disclosing the flagstaff of the distant fort, and the bannered masts of vessels, all of which brought vividly to mind our approach to the civilized world. If the Canadian boat-song was ever exhilarating and appropriate, it was peculiarly so on the present occasion; and when our _voyageurs_ burst out, in full chorus, with the ancient ditty, beginning, "_La fille du Roi son vout chassau, Avec son grande fusee d'largent_," they waked up a responsive feeling, not alone in the breasts of the French _habitans_, lining the shores of the river, but in our own breasts. On reaching the fort, the salute due to the governor of a territory was paid, in honor of our leader, Governor Cass; and in exchanging congratulations with the officers and citizens, we began first to feel, in reality, that, after passing among many savage tribes, our scalps were still safely on our heads. I found, at the fort, letters from my friends, and was thus reminded that warm sympathies had been alive for our fate. Weary regions had now been past, and privations endured, of which we thought little, at the time; the flag of the Union had been carried among barbarous tribes, who hardly knew there was such a power as the United States, or, if they knew, despised it; and some information had been gathered, which it was hoped would enlarge the boundaries of science, and would at the same time send a thrill of satisfaction, and impart a feeling of security, along the whole line of the advanced and extended western settlements. If Berkeley, in the dark days of the Commonwealth of England, could turn to the West, with exultation, as the hope of the nation, it must be admitted that it is by some out-door means, like this, that the way for the car of "empire" must be prepared.
