Excerpt from Report of the Puerto Rico Agricultural Experiment Station, 1932 A test was made to determine the difference in yield of oil from mature and from immature leaves. A charge of 550 pounds of leaves and 300 gallons of water, when distilled for hours, yielded about 60 gallons of distillate. The mature leaves yielded 0 cubic centimeters of oil, and the immature leaves, cubic centimeters. Probably the use of tender, young leaves would have given a still greater difference.

Excerpt from Report of the Puerto Rico Experiment Station, 1943 There are few pests of planted, growing, and stored food crops that are more destructive in their habits or harder to control than rats. The station frequently has experienced considerable interference with the seed-production pro-gram from this source. Areas near favorable cover, such as fence rows, ditch banks, or headlands and terrace banks covered with dense grass, have produced spotty stands because rats have dug up the seed and later, in the Case of corn, eaten into the ears that developed.

Excerpt from Report of the Federal Experiment Station in Puerto Rico, 1950 A higher yield was obtained from plantings Spaced 3 feet between plants, in rows 4 feet apart, than with the other planting distances tried. Plantings in May gave the highest yield, and the plants were more vigorous. During the dry season the plants did not reach nor mal height, and production was low. Plantings made at the lowest elevation (80 feet above sea level) gave best results. A planting at Las Mesas (about 900 feet above sea level) gave fair results, and at Toro Negro (about feet above Sea level) the plants were seriously stunted and consequently gave very low yields.
