Not illustrated. 1899 Excerpt: ...wide the long rafter is 18 feet and the short one 9 feet. An upright lVi-inch pipe supports them under the ridge with a branch holding a 1-inch purlin a foot below the ventilator headers, and another upright supporting another 1-inch purlin is needed half way between the plate and ventilator purlin. The ventilators of these houses are always on the south side of the ridge and open at the ridge; and as ventilation should be afforded to the fullest extent, it should be continuous and deep. It is thought necessary to raise the benches so that the plants should be at about an equal distance from the glass, and the benches are arranged in a 19-foot house as follows: The south bench 3 feet and path 18 inches or 2 feet The middle bench 6 feet and the back or north bench 3 feet.

If heated with hot water the pipes are mostly under the benches. If steam is used the flow is most likely raised above the plants and the returns under the bench. It Is as well to add, because it is the truth, that these houses, while getting the sun's rays in winter very obliquely, get it broadside in the summer, making them terribly hot houses in the summer months. The short-slope-to-the-south is also built sometimes 19 feet wide and sometimes 22 feet. The walls are of equal height, usually five feet. There is a path against the north and south walls and one dividing the two benchos, which are about 6 feet 6 inches each.
