For the proper application of the dolomite to land as manure, it should be freely burnt in a kiln, with a good quantity of wood, the ashes of which should be afterwards mixed with the burnt lime, and the whole exposed for several days to the action of the air, sheltered of course from the weather. The mixture should be applied just before the setting in of the monsoon rains: if the land be tolerably level, the lime may be scattered broadcast on the surface, though not quite near the plants. When the estate to be manured is steep, then the substance to be applied should be placed in ridges cut crossways to the descent of the slopes. About one cwt. to the acre would be ample for most lands; some may, however, require more. The contents of the husk pits might advantageously be mixed up with the burnt lime, when a sufficiency of it has been saved. A planter in Ambagamoe states that he has tried the following remedy for that destructive scourge, the coffee-bug, with great success. He applies saltpetre in a finely-powdered state, dusted over the tree when wet with rain or dew. The operation is inexpensive, as a very small quantity suffices, one cwt. being sufficient for nine or ten acres. It can be applied through a bamboo-joint covered with a perforated top, or any equally simple contrivance. Messrs. Worms' are reported to have found coco-nut oil an effectual remedy. To sum up the question of manures:-- Poonac, the marc or cake, after the coco-nut oil is expressed, is represented to be a stimulating manure; but is not durable. Lime is an useful application, especially to stiff soils, as the coffee tree contains 60 parts of lime. Bone-dust is an excellent fertiliser, but in Ceylon it is found that it cannot be applied at a less expense than £5 per acre. Cattle manure is the cheapest and most available. Guano does not seem suitable.
