Porto Rico. Coffee culture in Porto Rico dates from 1755 or even earlier, having been introduced from the neighboring islands of Martinique and Haiti. Count O'Reilly, writing of the island in the eighteenth century, mentions that the coffee exports for five years previous to 1765 amounted in value to $2,078. Old records show that in 1770 there was a crop of 700,000 pounds and that seems to be the first evidence that the new industry was growing to any noticeable proportions. For a hundred years, at least, only slow progress was made. In 1768 the king, of Spain issued a royal decree exempting coffee growers on the island from the payment of taxes or charges for a period of five years; but even that measure was not materially successful in stimulating interest and in developing cultivation.
Porto Rico is a good coffee-growing country; soil, climate, and temperature are well adapted to the berry. The coffee belt extends through the western half of the island, beginning in the hills along the south coast around Ponce, and extending north through the center of the island almost to Arecibo, near the west end of the north coast. But some coffee is grown in the other parts of the island, in sixty-four of the sixty-eight municipalities. Mountain sections are considered to be superior.
The largest plantations are in the region which includes the municipalities of Utuado, Adjuntas, Lares, Las Marias, Yauco, Maricao, San Sebastian, Mayaguez, Ciales, and Ponce. With the exception of Ponce and Mayaguez, all these districts are back from the coast; but insular roads of recent construction make them now easily accessible, and there is no point on the island more than twenty miles distant from the sea.

From the Sierra Luquillo range, which rises to a height of 1,500 feet, and from Yauco, Utuado, and Lares, come excellent coffees; and, on the whole, these are considered to be the best coffee regions of the island. A fine grade of coffee is also grown in the Ciales district. Figures compiled by the Treasury Department of the insular government for the purpose of taxation showed that for the tax year 1915–16 there were 167,137 acres of land planted to coffee and valued at $10,341,592, an average of $61.87 per acre. In 1910, there were 151,000 acres planted in coffee. In 1916 there were more than 5,000 separate coffee plantations.
Originally the coffee trees of Porto Rico were all of the arabica variety. In recent years numerous others have been introduced, until in 1917 there were more than 2,500 trees of new descriptions on the island.
The virgin land in the interior of the island is admirably adapted to the coffee tree, and less labor is required to prepare it for plantation purposes than in many other coffee-growing countries. It is cleared in the usual manner, and the trees are planted about eight feet apart, an average of 680 trees to the acre. The seeds are planted in February; and if the seedlings are transplanted, that is done when they are a year or a year and a half old. The guama, a big strong tree of dense foliage, is used for a wind-break on the ridges; and the guava, for shade in the plantation. Plow cultivation is generally impossible on account of the lay of the land, and only hoeing and spade work are done. Pruning is carefully attended to as the trees become full grown.
Flowering is generally in February and March, or even later. Heavy rains in April make a poor crop. Harvesting begins in September and extends into January, during which time ten pickings are made.
