rock that lies off the west coast of Ascension. This is now largely supplemented by the manure supplied by the cattle, the island being able to support a large number without any imported food. The rapidity with which sheep fatten on the grass is very satisfactory, nearly doubling their weight in three months after importation. The island is by no means free from vermin. The horses and cattle suffer greatly from a fly, in appearance like the house-fly, but which bites venomously, and causes intense irritation. The ‘black grub,’ as it is called there, effects great devastation at times among the plants, and as yet no practical remedy has been found for its ravages. The next destructive enemy is the field-rat, which attacks the root-crops, and feeds principally on the sweet-potato. Land-crabs, too, exist in very large numbers, and add to the destruction. Another animal, the wild-cat, proves itself an enemy, as it lives on the rabbits, and is useless as a vermin destroyer. A determined war is being waged against all these tormentors, a regular system of trapping having been set on foot. In one year, fifty-three cats, seven thousand four hundred rats, and eighty-five thousand one hundred and fifty land-crabs, were destroyed. The thorough cultivation of the ground is also being furthered by the introduction of rooks, minhas, and other birds that help the farmer. With all these drawbacks, the island has been brought step by step from its original barrenness to such a pleasing condition, that we now have over thirty-one acres under actual cultivation, producing among other things, sweet and English potatoes, cabbage, carrots, pumpkins, and turnips; pine-apples, bananas, endive, French beans, leeks, herbs, seedling date-palm, and coffee; sugar-cane, guavas, oranges, shaddocks, fig bushes, mulberries, and cuttings of shrubs. There is good pasturage one thousand acres in extent for cattle, and five thousand acres for sheep, supporting easily over forty head of cattle and between seven and eight hundred sheep. Parts of the island are now well wooded, and about forty acres are laid out in fruit-trees and shrubbery. Few brighter monuments could be pointed out of the success sure to attend the enterprise and unyielding zeal of a nation when well and wisely directed. THE MONTH: SCIENCE AND ARTS.
