The next morning (22d) we were released from our position on this bleak drift-coast, although the wind was still moderately ahead, and after toiling twelve hours adown the closing shores of the lake, we reached its foot, and entered the River St. Clair. Halting a few moments at Fort Gratiot, we found it under the command of Lieut. James Watson Webb, who was, however, absent at the moment. Two miles below, at the mouth of Black River, we met this officer, who had just returned from an excursion up the Black River, where he had laid in a supply of fine watermelons, with which he liberally supplied us. From this spot, we descended the river seven miles, to Elk Island, on which we encamped at twilight, having made fifty-seven miles during the day. Glad to find ourselves out of the reach of the lake winds, and of Eolus, and all his hosts, against which we may be said to have fought our way from Michilimackinac, and animated with the prospect of soon terminating our voyage, we surrounded our evening board with unwonted spirits and glee. Supper being dispatched, with many a joke, and terminated with a song in full chorus, and the men having carefully repaired our canoes, it was determined to employ the night in descending the placid river, and at nine o'clock P.M. all was ready and we again embarked. Never did men more fully appreciate the melody of the Irish bard:-- "Sweetly as tolls the evening chime, Our voices keep tune and our oars keep time." At half past three the next morning, we found ourselves at the entrance to Lake St. Clair, thirty miles from our evening repast. Owing to the dense fog and darkness, it was now necessary to await daylight, before attempting to cross. Daylight, which had been impatiently waited for, brought with it our old lake enemy, head winds, which made the most experienced men deem the passage impracticable. Counselled, however, rather by impatience than anything else, it was resolved on. Rain soon commenced, which appeared the signal for increased turbulence; but by dint of hard pushing in the men, with some help from our own hands, we succeeded in weathering Point Huron, the first point of shelter. The right hand shore then became a continued covert, and we successively saw point after point lessen in the distance. It was noon when we reached Grosse Point, the original place of our general embarkation on commencing the expedition; the rest of the voyage ran like a dream "when one awaketh," and we landed at the City of Detroit at half past three o'clock P. M. Gov. Cass, and his equestrian party from Chicago, had preceded us thirteen days, as will be perceived from the following article from the weekly press of that city, of September 15, 1820, which embraces a comprehensive notice of the expedition; its route, the objects it accomplished, and the effects it may be expected to have on the leading interests and interior policy of the country, as well as the drawing forth of its resources.
