band, so that it runs true or straight, without working either to the right or left. Another roller, A, is arranged for keeping the band properly stretched. Although relatively to the size of the machine a large extent of heating surface is here presented for drying the linen, yet over most of the surface there is little pressure of the linen against it.

The machine shown in Fig. 17 is a curious combination of those shown in Figs. 15 and 12 or 13. The cylinder is of considerable size, namely, 48 in. in diameter, and is heated by steam. An endless band of light canvas carries the linen against the under side of the cylinder, after it has been acted on by the top pressure-rolls; and, in combination with another endless band or apron, carries it back again, so as to deliver it on the opposite side to that where it was fed in. The machine was designed with a view to getting through a large quantity of work. It is, of course, expensive, and would appear to have most of the faults of the two machines of which it is a combination.

The machine illustrated in Fig. 18 is a combination of a Decoudin with that shown in Fig. 15. It has two beds and two felted rollers, so arranged as to act on both sides of the linen, having steam in the beds only and not in the rollers. After the linen has thus been doubly acted on, it is carried by an endless band of canvas around and against nearly the whole circumference of the large heated cylinder, which does not revolve, and is then carried some distance beyond it, so as to give time for the steam to clear away before it is delivered to the receiver. This machine appears to have many recommendations, and, at a speed of 30 feet per minute, will dry ordinary sheets with one pass through. It is the simplest machine there is of the kind. The
