meter so too. A little air ought to be admitted as soon 

 as the sun raises the heat a few degrees ; and in an 

 hour or two a little more, or as much as you think will 

 cause a sufficient circulation, without putting it out of 

 your power to keep up a sufficiency of moisture. If 

 there is absence of sunlight at the time of colouring, 

 fires ought to be applied to the house, raising the 

 temperature to 72 degs. at night, and maintaining a dry 

 atmosphere. If you have flowers in the vinery, take 

 them out. Should your grapes begin to colour in 

 March or April—the most precarious months in the 

 year — when the sun begins to shine, and there is 

 every prospect of a fine day, put out the fire imme- 

 diately ; and as the sun raises the temperature in the 

 house to 76' degs., give about half an inch of air to 

 every sash at top, but none in front upon any account; 

 and when the heat rises to 78 degs. give as much air 

 again, and so on until the thermometer stands at 85 

 degs. Be sure not to allow the heat to decline with- 

 out taking the air away by degrees, as it was given ; 

 ultimately, when closing the sashes, the house is at 

 76 degs. At the last movement of the sashes, half 

 an inch of air only should be shut off; for, if you 

 have a foot or six inches of air on each light when 

 the heat is at 85 degs., and you suffer the tempera- 

 ture to become colder without reducing the air a little, 

 then the berry shanks. In March and April, a day's 

 sunshine is very acceptable, and the gardeners throw
