SO injurious to the crop, and also from birds. Straw- 

 berry plants, to be cultivated in ground vineries, should 

 be planted early in autumn in narrow beds of two or 

 three rows, the plants close together in the rows, so as 

 to take full advantage of the glass-covered space. The 

 rows should be 9 inches apart, and the plants in the 

 row the same distance from each other ; 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 cultivator. If the ridges 

 are devoted to strawberries only, much care is required 

 in their culture, the runners should be carefully removed, 

 and the glass ridges taken off after the fruit is gathered, 

 and not replaced till November ; the plants will require 

 water and surface manure during the summer. 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 a in the figure, just under 

 the ridge, to let oat 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. 



On p. 153 I have given a diagram of a new plan 

 of ground vineries; it is exceedingly simple; gas-piping
