APR.] CHERRIES. 369 



fruit begin to colour, and swell off for ripening ; 

 being liberal in the waterings at root, and regular 

 in the exercise of the engine ; raising the tempera- 

 ture four or five degrees ; and encouraging as free 

 a circulation of air as the state of the weather vill 

 permit. 



When the fruit begin to swell off, withhold wa- 

 ter from the border by degrees, and towards their 

 being ripe, entirely. At this time also, watering with 

 the engine must be withheld ; but previously exer- 

 cise it with force, and often, for a week or two, so 

 as completely to subdue the red spider, if he have 

 gained any ground lately. After the crop is ga- 

 thered, these waterings must be resumed, and should 

 be continued till the foliage begin to drop j not, 

 however, so much on account of the cherry-trees, 

 as on account of other plants that may be placed in 

 the house ; for if the enemy be allowed a footing 

 on the former, he will soon shew himself on the 

 latter, where perhaps he may be less vulnerable, 

 especially if the plants be of a tender kind. The 

 border may be kept in a moderately moist state till 

 the leaves fall, or till the house be exposed, or be 

 uncovered. 



As the fruit ripen, give as large and regular por- 

 tions of air as possible ; opening the sashes by eight 

 or nine in the morning ; giving full air about ten $ 

 reducing about two or three ; and shutting up about 

 four or five, sooner or later, according to the state 

 of the atmosphere. In conducting this matter, how- 

 ever, regard must be had to the temperature ; but 

 air may be admitted, in sunshine, to such an extent
