As we have on a previous occasion hinted, the principle of ensilage has, after a manner, been applied for some years to fruit by the jam-makers. In years of plenty, fruit is reduced to pulp, and can in this state, if the air is carefully excluded, be made to keep well until a time of scarcity occurs. Large quantities of apricot pulp finds its way to this country from France, and realises a good price. In America, a clever plan of rapid drying and evaporation of the watery parts of fruit has come into vogue, and this industry gives employment to many workers. A stove constructed for the purpose costs about fifteen pounds. It is portable, and is used in many districts far from towns where there is not a ready market for fresh fruit. As the water slowly evaporates, the acid and starch in the fruit undergo a chemical change, and grape-sugar is formed. When placed in water, these dried fruits once more swell up to their original volume, and are in every respect like fresh fruit, only that they require, when cooked, but half the usual quantity of added sugar. All kinds of vegetables can be preserved by this process. A correspondent of the _Times_, writing from Iceland, gives some interesting particulars of the present condition of that island. At Reykiavik, its chief town, nothing was known of the reported volcanic disturbances in the interior of the island; but this is hardly to be wondered at, because a large portion of that area is occupied by snow-covered mountains and glaciers which the natives never visit, and which, it may be said, are never explored save by enterprising and adventurous tourists. Professor Tromholt is in Iceland, pursuing his researches on the aurora borealis, the frequency and brilliancy of which, coupled with the exceeding clearness of the atmosphere, give him every advantage. A large portion of Iceland still remains unexplored; and its mineral resources, if we except the large quantities of sulphur which are being worked by an English Company, are but slightly developed. There is still room for a brisk trade in coal, borax, copper, &c., which are abundant on the island. Besides these products, the fisheries of Iceland are most prolific; and although fish and its belongings form two-thirds of the total exports, it is believed that they offer a promising field for the further employment of capital.
