space. Tile rows should be 9 inches apart ; the beds 

 should be made every season on a fresh piece of rich 

 soil ; and as much fruit as can possibly be grown in 

 such a limited space must be the aim of the cultiva- 

 tor. In all cases the ridges should be placed on 

 bricks, with spaces between them. Ventilation is 

 then secured ; and even cauliflower plants in winter 

 will do well without the constant attention to " giving 

 air," so necessary in the old garden frame culture. 

 Lettuces, for early salads, succeed admirably in these 

 structures; they should be planted in October. In 

 gardens that are confined and very warm, I repeat, it 

 may be necessary to have a small opening left at the 

 top, at <z, in the figure, just under the ridge, to let out 

 the heated air, and two rows of bricks instead of one ; 

 but my vineries stand in a very exposed place, and do 

 not require it. I feel that I ought to tell my readers 

 the perfect success of my ground vineries this season 

 (1864). In four of them are growing four varieties, 

 one in each vinery, viz., Trentham Black, Black 

 Hamburgh, Buckland Sweetwater, and La Bruxelloise. 

 On these four vines are 100 bunches ; their berries 

 now (August 10) swelling rapidly. The only culture 

 they have had has been taking off about half the 

 number of bunches they produced, thinning the ber- 

 ries and stopping the shoots. No syringing, no water- 

 ing has been required, and not a red spider or any 

 other blight is to be seen. 



Any suburban garden 10 yards square, if in a sunny 

 situation, may have one or two of these vineries ; the 

 occupier may grow his own black Hamburgh grapes 

 known by most Londoners as " Hothouse grapes."
