AFR.] CHERRIES. S69 



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 will 

 permit. 



When the fruit begin to swell off, witlihold 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 

 exercise 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 

 gathered, these waterings must b^ resumed, and 

 should be continued till the foliage begin to drop ; 

 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 show 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, 

 however, regard must be had to the temperature ;
