. The American carnation; How to grow it. Ward, Charles Willis. GLASS. Forcing Houses for Carnations New Galvanized Iron U-Bar Construction These houses are con- structed upon a princi- ple entirely new and a ' radical departure from the standard type of iron frame greenhouse. The foundation consists of iron posts bedded in con- crete, to which posts is bolted an angle-iron base extending entirely around the house. The bars which are bolted to this base extend to the ridge, and are there con- nected by iron brackets, which also support the ridge. There is no plate or gutter at the eaves, the bars being bent at that point and curved glass used. There are no rafters in the house, the entire structure being self-supporting, the U-bars and ties forming a trussed arch. The purlins can be spaced as far as 9 feet apart. The bar is very small, measuring i!4 by i^ inches over all. The bars are made of steel, U-shaped, and filled with wood, which extends above the U- bar and forms a medium to which to attach the glass and prevents expan- sion and contraction of the metal bar. The glass is bedded in putty and rests on the edges of the U-bars, which are heavily galvanized. The sides of the house below the plate are of concrete. Practically the only wood exposed on the inside of the house is the doors, ridge and sash, while the only iron ex- posed on the outside of the house is the sills. Owing to the formation at the eaves it is claimed that this type of house frees itself of ice much quicker and more thoroughly than any other type, and the claim is also made that owing to the rigid construction and the manner in which the expansion and contraction are guarded against there is practically no glass breakage. The houses present an appearance of extreme lightness, strength and durability and the effect of the whole is exceedingly handsome. The construction is apparently exceptionally durable and the cost of repairs should be reduced to a minimum. iVevv Galvanized Iron U-Bai 159. P
