found most suitable for midseason and late vineries, through the temperature not being 

 so liaDle to sudden fluctuations as in structures with more acute roofs. This is impor- 

 tant in preventing the leaves and grapes scorching in the summer, while an equable 

 temperature is favourable to the keeping of grapes in good condition in the autumn. 

 "Where the climate is moist and the rainfall over 30 inches per annum, the angle may 

 be 30, which is ample for mid-season and late houses generally ; 35 to 40 answers

well for houses to ripen grapes in late May or early June ; and the earliest houses need 

 not have a steeper roof than 45. These angles and desirable widths of the structures 

 are indicated in the outlines and figures above the vinery (Fig. 83, A), in which due 

 provision is made for efficient heating and ventilation. 



The front-wall ventilators (/) should be hung on pivots, and opened and shut by 

 mechanical contrivance. Similar remarks apply to the back-wall ventilators (0), fixing
