We saw at the Exhibition of the Royal Agricultural Society, at Salisbury, in England, in July, 1857, the "pipe and tile machine," of W. Williams, of Bedford. It was in operation, for exhibition, and was worked by one man, who said he was a tile maker, and that he and one boy could make with the machine 7,000 two-inch tiles per day, after the clay was prepared in the pug mill. Four tiles were formed at once, by clay passed through four dies, and the box holds clay enough for thirty-two two-inch tiles, so that thirty-two are formed as quickly as they can be removed, and as many more, as soon as the box can be refilled. The size, No. 3, of this machine, such as we then saw in operation, and which is suitable for common use, costs at Bedford $88.50, with one set of dies; and the extra dies, for making three, four, and six-inch pipes, and other forms, if desired, with the _horses_, as they are called, for removing the tiles, cost about five dollars each. This, like most other tile machines, is adapted to making tiles for roofs, much used in England instead of shingles or slates, as well as for draining purposes. There are several machines now in use in England namely: Etheridge's, Clayton's, Scragg's, Whitehead's, and Garrett's--either of which would be satisfactory, according to the amount of work desired. We have in America several patented machines for making tiles, of the comparative merits of which we are unable to give a satisfactory judgment. We will, however, allude to two or three, advising those who are desirous to purchase, to make personal examination for themselves. We are obliged to rely chiefly on the statements of the manufacturers for our opinions. [Illustration: DAINES' DRAIN TILE MAKER] Daines' American Drain Tile Machine is manufactured at Birmingham, Michigan, by John Daines. This machine is in use in Exeter, N. H., close by the author's residence, and thus far proves satisfactory. The price of it is about $100, and the weight, about five hundred pounds. It occupies no more space than a common three-and-a-half foot table, and is worked by a man at a crank. It is capable of turning out, by man power, about two hundred and fifty two-inch tiles in an hour, after the clay is prepared in a pug mill. Horse or water power can be readily attached to it. We give a drawing of it, not because we are sure it is the best, but because we are sure it is a good machine, and to illustrate the principle upon which all these machines are constructed. Pratt's Tile Machine is manufactured at Canandaigua, New York, by Pratt & Brothers, and is in use in various places in that State as well as elsewhere. This machine differs from Daines' in this essential matter, that here the clay is _pugged_, or tempered, and formed into tiles at one operation, while with Daines' machine, the clay is first passed through a pug mill, as it is for making bricks in the common process.
