Hevea Rubber Plantings Ruined by the Leaf Disease 
Fig. 1.— This view (at left), from the southern portion of the island of Trinidad, shows rubber 
trees, interplanted with cacao, which have been repeatedly defoliated by 1 lie loaf disease. Many 
of the branches have recently died back, while on other trees, as in the upper left-hand corner 
of the illustration, the foliage has the characteristic thin appearance because of stunting, distor- 
tion, and loss of occasional leaflets. Ftg. 2.— A rubber planting in Dutch Guiana (a1 right), 
which illustrates the typical result of prolonged attack from the leaf disease. All Mil a few of 
the branches of these trees, 10 to 12 years old, have died back, and the trunks scarcely approxi- 
mate in size a normally developed 5-year-old tree
