orsicano said: 'Diavolo, let the cacao-trees grow, let them branch off like any other fruit-tree, say the tamarind, the 'chupon' or sucker will in time bear more than its mother.'"[3] There seems to be some evidence that old trees profit from the "chupons" because they continue to bear when the old trunk is weary, but this is compensated for by the fact that the "chupons" (Portuguese for suckers) were grown at the expense of the tree in its youth. Hence other planters call them "thieves," and "gormandizers," saying that they suck the sap from the tree, turning all to wood. They follow the advice given as early as 1730 by the author of The Natural History of Chocolate, when he says: "Cut or lop off the suckers." In Trinidad, experiments have been started, and after a five years' test, Professor Carmody says that the indications are that it is a matter of indifference whether "chupons" are allowed to grow or not.

After hunting, agriculture is man's oldest industry, and improvements come but slowly, for the proving of a theory often requires work on a huge scale carried out for several decades. The husbandry of the earth goes on from century to century with little change, and the methods followed are the winnowings of experience, tempered with indolence. And even with the bewildering progress of science in other directions, sound improvements in this field are rare discoveries. There is great scope for the application of physical and chemical knowledge to the production of
