1PORTO RICO

THE island of Porto Rico, oblong in shape, about 36 miles from north to south and 100 miles from east to west, is the farthest end of the Greater Antilles. It lies between 65 and 68 degrees west longitude and 18 and 181/2 degrees north latitude and is about 1,500 miles east of New Orleans.

  Surface and soil.  The greater part of Porto Rico is rough and broken, yet the highest elevations are only about 3,000 feet.  The main range of mountains extends from east to west. Of the 3,600 miles making up the total area, about one

tenth consists of islands bordered by low lands of greater or less extent.   Inland there are many deep and narrow valleys.  Much of the soil of Porto Rico has been formed by the decay of volcanic rock like that forming the backbone of the island, yet the soil varies greatly.  In respect to area, red clay is one of the principal soils.  Foothill soils, bordering the plains, are dark in color. The soil of the mangrove swamps contain coral sand with some organic matter.  Near the seacoast there is much coral sand. Most of the rocks of Porto Rico are limestone, but there is some granite, marble and sandstone. Practically

all of the island was once heavily timbered, but most of the timber has been removed.
