Theduuljltj-huarded side.s, vLen erected with care, are warmer thau ordinary masonry wiiUs. Oast-iron g;utters are provided to collect the rain- water from the roof. By exposing the inner side of these gutters to the heat of the house, they are kept free of ice in the winter. ISmall metal clips fastened with screws are used to connect the wood sash bars to the cast-iron gutters, angle-iron plates and purlins. This method of securing the sash bars in phice is very convenient in case of repairs, and ren<lers the structure practically portable.

It is pre- ferred for vineries and fruit houses, as the form allows the canes to be supported on the line of the roof with- out a sharp bend at the plate line.
