States. It is formed by the junction of the Monongahela and Allegany 

 rivers at Pittsburg in Pennsylvania. It flows through a beautiful and 

 fruitful country, and falls into the Mississippi in 36° 43' north latitude. 

 Its shores are dry and healthy, and covered with numerous and flou- 

 rishing settlements. Following the windings, which are numerous, 

 its length has been computed at 1033 miles. In its course it receives 

 the waters of the Muskingum, Kenhawa, Sandy, Sciota, Miami, Ken- 

 tucky, Wabash, Licking, Tennessee, Cumberland and Green rivers, 

 with numerous smaller streams. Its navigation is frequently inter- 

 rupted by rich and well timbered islands. The greatest impediment, 

 however, to the navigation of the Ohio, are the falls just below Louis- 

 ville. A lock canal, in this place, would be of immense value to the 

 Ohio trade. Its greatest breadth, which is at Louisville, is 1200 yards. 

 At Pittsburg it is 440 yards wide, and at its mouth 900. The ave- 

 rage width is about 600 yards. 



The Connecticut is the most considerable river of NeAV England. 

 Its course is rapid and interrupted by numerous falls. It takes its 

 rise on the borders of Lower Canada, and pursuing a southwardly 

 course, forms the boundary line between the states of Vermont and 

 New Hampshire. It then passes through Massachusetts and Con- 

 necticut ; and discharges into Long Island sound, after running a 

 course of 410 miles. 



The Delaware called by the Aborigines Poutaxat, rises among the 

 mountains in the south-east part of the state of New-York. It divides 

 the states of Pennsylvania and New- Jersey, and runs nearly in a south- 

 wardly direction, to the bay of Delaware ; where it unites with the At- 

 lantic Ocean. The tide flows about one hundred and thirty miles, or 

 to Trenton falls, thirty miles above Philadelphia, rising about 6 feet 

 with a common flood. At the city it is a mile wide, and navigable by- 

 ships of 1200 tons burden ; but above Trenton it is only passable by 

 flat bottomed boats. The length of the Delaware to the bay is three 

 hundred miles, from thence to the capes the distance is sixty-five miles. 

 The northern branch of the Patoivmac rises among the Allegany 

 mountains, and forms the boundary line between the states of Ma- 

 ryland and Virginia. It runs north-cast one hundred and forty miles 

 to Cumberland, where it approaches within a few miles of the Penn- 

 sylvania line. Thence it pursues a south-east direction to near Old 

 town, where it unites with the south branch, which has its source in 

 Pendleton county, Virginia, upwards of one hundred miles from the 

 union. Thence it again runs north-east to its most northwardly point, 

 which is about four miles south of the Pennsylvania line. Thence its 

 course is south-east to the Chesapeake, which it enters in lat. 38° north. 

 The tide, runs three miles above the city of Washington. Between 

 Cumberland and Washington there are five falls or rapids, the most 

 considerable of which are 15 miles above the city, and fall seventy -six 

 feet. At its junction with the Shenandoah, the river passes with con- 

 siderable rapidity through the Blue mountain, which is there more than 

 one thousand feet in height. Canals have been cut round all the falls. 

 The Roanoke is formed by the union of the Staunton and Dan rivers, 

 twelve miles from the southern boundary of Virginia. The Staun- 

 ton rises among the Allegany mountains, in Montgomery county, 

 Virginia. Its course is south-east one hundred and ten miles, till its 

 junction with the Dan- The latter rises among the same mountains, 

 in Patrick county, in the same state. It runs south 17 miles, when 

 it enters North Carolina. In its course, it crosses the boundary line, 

 between the two states, in eight different places. After passing it at
