of 2 feet between, and opposite each space a viue 

 is to 1)6 planted inside the house, as hereafter de- 

 scribed. Strong capstones, thick enough to come slightly 

 above the surface of the border and about 18 inches 

 wide, are then laid from pier to pier. On such a founda- 

 tion a superstructure can be erected with some eonfi- 

 denoe. For the hsLne of the supersti-ucture masonry is 

 preferable, about 18 inches in height being necessary 

 before the glass work begins. A hollow wall, constructed 

 of hard brick and cement, is desirable, and openings 

 should be left for ventilation. The upper surface of 

 these walls should be covered with cement. If con- 

 structe<l of wood, the same general plan should be car- 

 ried out, using the most durable kiud only. 



Aside from its durability, masonry has an advantage 

 over wood in being a better equalizer of temperature, 

 and the heavy back wall of a lean-to house can be made 

 of great value for this purpose. The general plans of 

 the superstructure are shown in the illustrations. It 

 should present as much glass surface as possible. The 

 frame can be of iron or wood, as preferred. Light, heat 

 and moisture are the great features desired, also a gen- 

 erous supply of air under favorable conditions. The 

 glass should be of good quality, otherwise blisters will 

 burn the foliage and fruit. Small ventilators covered 

 with wire gauze should be built in the foundation walls, 

 and large ones at the upper part of the house. Ventila- 

 tion should always be free from a draft or sudden 

 change of temperature. A draft is just as unpleasant 

 to a sensitive vine in a house as it is to a human being, 

 and if subjected to it disease is sure to follow, mildew 

 being the tirst evidence; and yet a generous supply of 

 air is a prime requisite in growing Grapes under glass, 

 especially duriug the ripening period. Previous to that 

 time the lower ventilators should be very carefully used, 

 some growers never opening them until the Grapes be- 

 gin to color, and the new growth and foliage are some- 

 what hardened. More or less air is always admitted 

 around the glass in a very equable manner and thence 

 to the upper ventilators. 



The modern heating apparatus, consisting of a boiler 

 in an adjacent pit for heating water, with circulating 

 pipes throughout the house, as shown in illustralicms ,.u 

 Greenhouse, is a very perfect and economical Mipi'lii f 

 of heat, and it should be erected by a praciic;il lunliln.

 full of Grapes, and, while it can be dispensed with, its 

 advantages are very material. 



It is possible to fruit Grapes in benches in pots, re- 

 moving the pots when the fruit is past, and using the 

 house for other purposes (Fig. 977). 



The Border. — A good border is of great importance, as 

 no permanent success can be obtained 

 without it, and probably the difference 

 between success and failure more 

 often lies here than in any other 

 feature. 



It is a good plan to construct 

 vineries so that their borders can 

 be somewhat elevated above the 

 surrounding ground, as better 

 drainage is thus secured, and 

 good drainage is imperative 

 (Fig. 9751. The border 

 should fill the house in- 

 side and extend outside 

 adjacent to where the 

 vines are planted at 

 least 6 feet when tirst ^. , „„

prepared manure, one part old plaster or mortar, and 

 one part of ground bone, all to be well composted to- 

 gether, will meet all the requirements. If the subsoil is 

 clay, a foundation of old brick and mortar is very desir- 

 able to insure drainage. The border above this should 

 be from 2 to 3 feet in depth. No trees or shrubs should 

 be permitted to extend their roots into it, a very com- 

 mon cause of trouble, and nothing whatever should be 

 grown on it, although the temptation to try a few melons 

 or some lettuce is often too great to be overcome, and

these probably do a minimum of damage. In such a 

 border, if properly supplied with water, the viue roots 

 will remain at home, and not go wandering off into 

 trouble. Where extra early work is not desired, no at- 

 tempt should be made to keep the frost entirely out of 

 the border during the winter, as this is apt to result in 

 a heavy, sodden surface in spring. It is better to spade 

 it up roughly just before winter and cover with a good 

 coat of manure, permitting the frost to enter the ground 

 some inches. In the spring it is dug over again and, 

 when rakeil off, presents a rich, lively surface. The in- 

 xi.li- l.cir.l.r is to be covered with a coat of well-rotted

The Vines. — Tha amateur should purchase these from 

 some nurseryman of established reputation. Vines 1 or 

 2 years old are better than older ones. For supporting 

 the vines, light cast-iron brackets are secured to the 

 rafters, and these suiqiort wins running lengthwise of 

 the house about L'j iiich.s fnuu the glass, and to these 

 wires the vines are tii-il as fast as they grow. The vines 

 are to be planted inside the house about a foot from the 

 front wall and about 4 feet apart, placing one opposite 

 each opening in the fouudation as before described. It 

 is not desirable to plant them along the back wall of a 

 lean-to house. They should be cut back to two or three 

 buds near the ground, and when these start the strong- 

 est shoot only is selected for training and the others 

 rubbed off. As this shoot advances it is tied to the wires, 

 and it may reach the limit of the house by July 1, or 

 perhaps not until September 1, depending on the care, 

 the vigor of the vine, and the border. Once there, the 

 end is pinched and the cane continues to strengthen and 

 increase in size and store up material in the lateral 

 buds until the end of the season, when it is taken down 

 and pruned to one-third its length, laid on the ground 

 and covered from the sun for the winter. Care should 

 be taken that mice do not eat out the buds, as once out 

 they can never be restoreii. In the spring of the second 

 year, or as soon as it is desired to start the vines, they 

 are tied up again, and the terminal shoot again trained 

 to the top of the house, where it is stopped as before.
