Greenhouse construction and heating: containing full descriptions of the various kinds of greenhouses, stove houses, forcing houses, pits and frames, with directions for their construction, and also descriptions of the different types of boilers, pipes, and heating apparatus generally, with instructions for fixing the same. Greenhouses. HEATING BY HOT WATEE. 187 extant. They also heat very quickly, and if properly set and worked are by no means extravagant in fuel—this may at least be truly said of the newer and improved forms, such as the Champion, made by the Thames Bank Iron Co. (see Fig. 127), though some of those first constructed undoubtedly consumed a large amount of fuel in proportion to the amount of work done. These boilers being entirely constructed in sections, and the tubes being easily removable, have also considerable advantages, as a cracked or faulty tube can be taken out and replaced in a very short time. This class of boiler can also be set in comparatively shallow stoke-holes, and one form with only a single row of pipes over the furnace, though scarcely as economical in work- ing as those in which the draught is taken forward and backward again. A very great improvement in the heating power and general efficiency of this type of boiler has been effected by casting the pipes vnth a web or feather on each. This, when the pipes are fixed as shown, prevents the heated air, etc., from passing too directly into the chimney, and forces it to travel the whole length of the boiler and back twice or thrice, when it will have parted with the greater part of its caloric. Where, however, special or important work, such as forcing, etc., is carried on it is always advisable to set.
