The Tennessee River is the largest branch of the Ohio. It rises in Virginia and runs south westward about 1000 miles from its junction with the Ohio. Its cur- rent is so uniformly rapid, that ii requires eight men to proceed wiah4a beat sss-nasles day. This cannot be done better than by pulling the boat forward, by the bushes on the shore. Its general width is from so 10 100 rods. A boat will descend by the rae pidi,y of the stream sixty to eighty or even hundred miles in day, according to the season. In summer, the water of the river is so warm that it is unpleasant, unless cool ed on the deck of the boat, by the air of the night.

 The Muscle Saoals are about 800 miles from its entrance into the Ohio. Al ,h.s place, the river spreads to the width O.! 3 miles, and forms number ofislands. The passage by boats is difficult and dangerous, except when water is high.

 From these shoals to the place called the TVArl 0, Suck, 25O miles. the navig a!ion all the way is excellent, 10 the Cumberland Mountain; where the river breaks through. This mountain is sometimes so steep, that even the Indians cannot ascend it on foot. Tn one place, particularly, near ,he summit of the mountain, there is large ledge of rocks, of about thirty miles in length and 200 feet high, with perpendic- ular front facing the south east, more noble and grand than any artificial ,fortification in the known world; and apparently equal in point of regularity.

 The Whirt, as it is called, is about lat. 35 deg. IL is rcckoned a greater curiosity than the bursting of the river Potomac through the Blue Ridge, so well described by Mir. Jefferson.

 The river, which is above half a mile wide, is here compressed to 100 yards, or eighteen rods. Jus, at the entrance of the mountain, large rock projects from the northern shore, in an oblique direction, which renders the channel still narrower. This causes sudden bend, by which the waters are thrown with great force against the opposite shore. From thence they re- bound about the point of the rock, and pro- duces whirl of 80 yds. or 240 feet in cir conference. By the dexterity of the row. CTS, canoes drawn into this whirl have sometimes escaped without damage. Jn less than a mile below the whirl, the river spreads to it's common width, down to the Muscle Shoals and thence runs in regu- lar and beautiful stream to its confluence with the Ohio.-Hambler.

 Heat 8- LigM.-Innumerable operations of nature proceed as regularly and as efiec- tually in the absence of light as when it is present. The want of that sense which it is designed to affect in the animal economy in no degree impairs the other powers of the body, nor in man does such a defect in- terfere in any way with the faculties of the mind. Light is, so to speak, an article of luxury rather than of positive necsssity.- Nature supplies it, therefore, not in an un- limited abundance, nor at all times and pla- ces, but rather with that thrift and econo- my which she is won't to observe in dispeu-
