space. The rows should be 9 inclies 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. YentUation 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 a, 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 pi'oduced, 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."
