Design No. 4
This design combines a grapery, and forcing, and propagating house in one. Figs. 13, 14, 15, show side elevation, south front, and section through the centre. The dimensions are twenty feet in width by forty three feet in length, to which ten feet have since been added, enclosing boiler pit C. and potting room not shown in sketch. The foundation is built on locust posts with plank nailed upon both sides. Such foundations we do not advocate, as they are a bill of expense, for needful repairs, every four or five years, and the additional outlay for permanent brick or stone foundations is money well invested. In the present case, the owners wishes were carried out. On the ground plan, that part designated A. is devoted to the growth of grapes. The border is all inside of the house and is about three feet in depth. At the dotted line a wall is built across the house to sustain the border, the floor of B. being two feet lower. The central portion of B. is devoted to grapes in pots. At the sides of B. are beds for propagating plants, forcing vegetables, &c., furnished with bottom heat from brick tanks which extend entirely around the house and heat the grapery part as well.
Pipes laid underground from the outside furnish fresh air when desired and ventilation in the roof is also provided for.
