A comparatively low cost of labour, the fact that labour is not, as in the days of slavery, that of unintelligent blacks but of intelligent free labourers, the centralized organization and modern methods that prevail on the plantations, the remarkable fertility of the soil (which yields 5 or 6 crops on good soil and with good management, without replanting), and the proximity of the United States, in whose markets Cuba disposes of almost all her crop, have long enabled her to distance her smaller West Indian rivals and to compete with the bounty-fed beet.
To prevent the gradual destruction of the forests by unskilful management and depredations, schools of forestry have been founded, and means have been taken for regulating the cutting of wood and for replanting districts that have been partially denuded.
This has led to restrictive measures, the vines being tapped under definite regulations as to the manner and time of tapping, and also to requirements as to replanting vines to take the place of those which have been injured or destroyed, certain areas being periodically closed.
The third plan, which consists in replanting the affected vineyard with American vines - such as the Vitis labrusca, V.
In the grand duchy the forest has almost entirely disappeared, but owing to the compulsory law of replanting in Belgium this fate does not seem likely to attend the Belgian Ardennes.
Others, as the asters, spread rapidly; those possessing this habit should be taken up every second or third year, and, a nice patch being selected for replanting from the outer portions, the rest may be either thrown aside, or reserved for increase; the portion selected for replanting should be returned to its place, the ground having meanwhile been well broken up. Some plants are apt to decay at the base, frequently from exposure caused by the lifting process going on during their growth; these should be taken up annually in early autumn, the soil refreshed, and the plants returned to their places, care being taken to plant them sufficiently deep.
The town was formerly much exposed to avalanches and floods, which are now less frequent owing to the construction of embankments and replanting of the hillsides.
On the other hand, the replanting of some of the French vineyards (after the ravages due to the phylloxera) with American vines, or, as was more generally the case, the grafting of the old French stock on the hardy American roots, resulted, after a time, in many cases, in the production of wines practically indistinguishable from those formerly made.
Many remedies for this disease have been suggested, including total submersion of the vineyards, the use of carbon bisulphide for spraying, and of copper salts, but there appears to be little doubt that a really serious epidemic can only be dealt with by systematic destruction of the vines, followed by replanting with resistant varieties.
Were destroyed under the Phylloxera Act, but replanting subsequently revived this industry.
