The CouIes Wafer-Tube Boiler.—The Cowles boiler (Fig. 13) is one of a numerous class ofboilers recently designed to combine great steaming capacity, at the highest steam pressures,with the miniinum weight of structure and water contained, and minimum space this combination can be obtained to the highest degi-ee in what is Known as a coil-boiler, which consists of simply a mass of coils of iron or copper tubes of small diarneter, anda furnace underneath them. Such coil boilers, however, are usually defective in
