While the most desirable form in which potash can be applied is in the form of the sulphate, excellent results have been had with the use of Kainit or Stassfurth salts, and as a still more available substitute, wood ashes is suggested. When forest lands are near, the underbrush may be cut and burned in a clearing or wherever it may be done without detriment to the standing timber, and the ashes scattered in the orchard before they have been leached by rains. The remaining essential of phosphoric acid in the form of superphosphates will for some years to come necessarily be the subject of direct importation. In the cheap form of phosphate slag it is reported to have been used with great success in both Grenada and British Guiana, and would be well worthy of trial here. Lands very rich in humus, as some of our forest valleys are, undoubtedly carry ample nitrogenous elements of fertility to maintain the trees at a high standard of growth for many years, but provision is indispensable for a regular supply of potash and phosphoric acid as soon as the trees come into heavy bearing. It is to them and not to the nitrogen that we look for the formation of strong, stocky, well-ripened wood capable of fruit bearing and for fruit that shall be sound, highly flavored, and well matured. The bearing life of such a tree will surely be healthfully prolonged for many years beyond one constantly driven with highly stimulating foods, and in the end amply repay the grower for the vigilance, toil, and original expenditure of money necessary to maintaining a well-grown and well-appointed cacao plantation. SUPPLEMENTAL NOTES. New Varieties.--Cacao is exclusively grown from seed, and it is only by careful selection of the most valuable trees that the planter can hope to make the most profitable renewals or additions to his plantations. It is by this means that many excellent sorts are now in cultivation in different regions that have continued to vary from the three original, common forms of Theobroma cacao, until now it is a matter of some difficulty to differentiate them. Residence.--The conditions for living in the Philippines offer peculiar, it may be said unexampled, advantages to the planter of cacao. The climate as a whole is remarkably salubrious, and sites are to be found nearly everywhere for the estate buildings, sufficiently elevated to obviate the necessity of living near stagnant waters.
