Sectional cast iron boilers which are moderate in first cost, low maintenance and extremely economical in fuel. Sectional view shows large combustion chamber and vertical waterways of small area. The latter absorb the heat quickly, circulate the water rapidly and make dry steam. May be fired with anthracite coal, wood, coke
or fuel gas.

The H. B. Smith Company
Boilers and Radiators
Princess Direct Radiators
For sanitary reasons, radiators with wide spacing should be demanded.
If ordinary radiators are not sanitary enough for hospitals, they are not sani tary for the home. To meet hospital specifications, some manufacturers make special radiators with wide spacing and charge an increased price.
Princess Radiators are the standard radiators of The H. B. Smith Co. and are sold at regular list prices.
Princess Wall Radiators
Suited for all places where direct radiators or pipe coils cannot be used. Espe cially desirable in locations where floor space is valuable and where wall, column or ceiling space is more available. They possess extreme flexibility of size and arrange ment. Made in two heights, 15 and 22 in. Can be furnished with heating surfaces from 5 sq. ft. up, in multiples of 2% sq. ft. Corresponding lengths in 22 in. radiator are from 9 in. up, in multiples of 4 in. (1 in. allowed in over all length for plugs and bushings). In the 15 in. radiator, corresponding lengths are from 13 in. up, in multiples of 6 in. By combinations of the two heights, these radiators can be arranged in tiers, either for horizontal runs or for column work. Hung horizontally, they make excellent . ceiling radiators.
