The buildings occupied by the International Fisheries Exhibition at South Kensington are, in 1884, to be devoted to a no less important object, albeit it is not likely to be so popular with the masses. This Exhibition will deal with matters relating to Health and Education. It will include the food-resources of the world; the best means of cooking that food; the costumes of the world, and their bearing upon health; the sanitary construction of dwellings; and many other things that every one ought to know about, but which very few study. With the Prince of Wales as President, assisted by a Council including the names of Sir Cunliffe Owen and Mr Birkbeck, the success of the scheme ought to be assured. In Cannon Street, London, an experimental section of roadway of a novel kind has lately been laid down. It is the invention of Mr H. F. Williams, an engineer of San Francisco, where the system has been most successfully employed for the past seven years. Indeed, the roads so prepared are said to be as good as when first laid down, allowing for a reasonable amount of wear and tear. The process is as follows. First of all is provided a good dry concrete foundation; upon this are laid blocks of wood, grain-end uppermost, measuring eight inches by four, with a thickness of an inch and a half. Each block, before being placed in position, is dipped halfway into a boiling mixture of asphalt and Trinidad bitumen; this glues the blocks to the foundation and to one another, at the same time leaving a narrow space all round the upper half of each piece of wood. This space is afterwards filled in with boiling asphalt. Above all is spread a half-inch coating of asphalt mixed with coarse grit, the object of which is to prevent that dangerous slipperiness that is common to asphalt roadways in moist states of the atmosphere. At Brooklyn, the sanitary authorities seem to have a very sensible method of dealing with milk-dealers in the matter of adulteration. They invited the dealers to meet in the Common Council Chamber, when it was explained to them by an expert how they could determine by various tests whether the milk purchased from the farms is of the required standard. At the conclusion of this conference, it was hinted that the licenses of such dealers as were thenceforward detected in selling adulterated milk would be peremptorily revoked.
