The island of Santo Domingo or Haiti, after Cuba, is the largest of the West India Islands. It was discovered by Columbus on his first voyage in 1492. It is situated between latitude 17°35′ North and 20° North so that it is well within the tropics, and lies between Cuba on the west and Puerto Rico on the east. Although it is within the tropical zone, it has an equable climate, on account of the prevalence of the northeast trade winds. The records of the Department of Agriculture of the Dominican Republic show that from 1910 to 1917 the average mean annual temperature was 77.9°. The average mean monthly temperature during this period exceeded 80° F. in June, July, August and September, only. The highest recorded temperature during the seven years referred to was 93.2°; the lowest, 56.8°. The average monthly rainfall was 4.3 inches.
