_Planting the Dadap tree_.--This is a species of Erythrina, probably _E. indica_, or _E. arborescens_; that used for the purpose in the West Indies is _E. Corallodendrum_. In Java, as soon as the coffee is planted, the operation of planting the dadap tree is commenced. The best sort of dadap comes from Serp or Mienyak; it is smooth and broad-leaved, and shoots up quickly. Thick young stems are chosen, about three feet long, and the lower part is pointed off. If the dadap is moist or juicy, it should be cut twenty-four hours before it is planted. The dadap is planted uniformly by measuring the cane in the same way as the coffee itself. Between every two rows of coffee one of dadap is planted, not on a line with the coffee plants, but alternately with them; thus, if the coffee is eight feet by eight, the dadap is sixteen by sixteen. The dadap is planted to the depth of a foot, with somewhat of a westerly inclination, in order that the morning sun may fall on a larger surface of the stick. The ground must be stiffly trodden round the bottom of the stem, and the upper part of it should have some kind of leaf tightly bound around it to prevent the sap from escaping. When the coffee and dadap plants have thus been put out, every fifth day the young plantation should be carefully inspected, and a picket placed wherever there is a failure, as a mark to the planter that a new plant is there required. This operation of replacing failures is carried on all through the wet season, and the dadaps which have not succeeded are at the same time changed. _Keeping up the estate_.--In the first six months after planting, the estate should be cleaned each fortnight with the hoe; the ground being well moved and the weeds taken out. Those weeds which are too close to the plants to be removed in this manner, must be pulled out with the hand. When the plantation is thus wholly or partially cleaned, the earth must be taken off the weeds, and they must be collected and thrown on the pathways. The weeding in this manner gives at first a great deal of trouble, but it is most advantageous in the long run, as the weeds are thus easily kept down. Great care must be taken to do away with an old custom of burying the weeds in large holes on the estates. It conduces to bad and slovenly habits, such as cutting off the tops of the weeds by wholesale, and thus giving the plantation an appearance of cleanliness, whilst it, in fact, is as dirty as ever. This is soon discovered by the weeds showing themselves again above ground in a very few days, and even if they rot under ground, they breed insects which are very hurtful to the bushes, and the seeds vegetate.
