Protection River: After 1618, when land grants to individuals began to be made, plantations developed along the James River from its mouth to the falls, and near the falls a trading post was established. Between 1622 and 1644 there was a period of uneasy peace with the Indians, and following surprise attacks on the settlements in the latter year, Fort Charles was established for protection river near the falls. The fort was garrisoned by William Byrd I, who had inherited property on both sides of the river, under an agreement by which he was granted additional lands in the adjacent area.
None of the countries of South America is so dependent upon river transportation as Colombia is upon the waters of the Magdalena. Travel on this river is much in the manner of that on the Mississippi from 1840 to 1850, with the exception that short railways are used to transport goods around the many obstacles which interrupt the smooth flow of the river. The river mouth has become choked with debris so that ships formerly had to land at Puerto Colombia and goods were carried by rail a distance of 18 miles to Barranquilla, 10 miles up the Magdalena River.
