Mr. Thomas Say, of Philadelphia, who accompanied Major Long on his expedition to the Rocky Mountains, also resides here. He too is a recluse, and is now preparing a work on his favourite subject, natural history. His garden contains a tolerable collection of Mexican and other exotic plants. Harmony is built on the second bottom of the Wabash, and is perhaps half a mile from the river at low water, the first bottom being about that breadth. Mosquitos abound here, and are extremely troublesome. There are several orchards in the neighbourhood well stocked with apples, peaches, &c.; and the soil being rich alluvion, the farms are productive--so much as fifty dollars per acre is asked for cleared land, close to the town. There is a great scarcity of money here, as in most parts of Indiana, and trade is chiefly carried on by barter. Pork, lard, corn, bacon, beans, &c., being given, by the farmers, to the store-keepers, in exchange for dry goods, cutlery, crockery-ware, &c. The store-keepers either sell the produce they have thus collected to river-traders, or forward it to New Orleans on their own account. We made an excursion down the river in true Indian style. Our party, consisting of four, equipped in a suitable manner, the weather being then delightfully warm, having stowed on board a canoe plenty of provisions, paddled down the Wabash. The scenery on the banks of this river is picturesque. The foliage in some places springs from the water's edge, whilst at other points it recedes, leaving a bar of fine white sand. The breadth of the Wabash, at Harmony, is about 200 yards, and it divides frequently on its course to the Ohio, forming islands of various degrees of beauty and magnitude. On one of these, about six miles from Harmony, called the "Cut-off," we determined on encamping. Accordingly, we moored our canoe--pitched our tent--lighted our fire--bathed--and having acquired enormous appetites by exertion, commenced the very agreeable operation of demolishing our provisions. We roamed about that and an adjacent island, until evening, when we returned to regale. These islands are generally covered with "cane brakes," and low brush wood, which renders it difficult to effect a passage across them. Cotton-wood, beech, maple, hickory, and white oak, are the trees in greatest abundance. Spice-wood, sassafras, and dittany, are also plenty. Of these a decoction is made, which some of the woods-people prefer to tea; but it is not in general repute. The paw-paw tree (_annona triloba_) produces a fruit somewhat resembling in taste and shape the fig-banana, but certainly much inferior to that delicious fruit. We saw several deer in the woods, and some cranes upon the shore. With smoking, &c., we passed the evening, and then retired--not to bed, for we had none--but to a right good substitute, a few dry leaves strewn upon the ground--our heads covered by the tent, and at our feet a large fire, which we kept up the whole night.
