PINK. 73 



remain open, but not exposed to a hot sun till 

 their leaves become perfectly dry, after which the 

 glass is to be placed over them carefully on the 

 same mark that was made by it upon the surface 

 of the soil. The bottom edges of the glass are to 

 be forced a little into the earth to prevent the ad- 

 mission of too much air. The soil should be 

 kept regularly moist till they have formed their 

 fibres ; but too much moisture is as prejudicial as 

 too little ; and whenever they are watered, the 

 glasses are never to be replaced over them till 

 their leaves are perfectly dry. The pipings 

 should have a little of the morning sun, but must 

 be shaded from it when the heat becomes con- 

 siderable : this will be easily efiected by placing 

 mats upon a slight frame of hoops or laths erected 

 over the bed about two feet above it. 



" The glasses should be occasionally taken off 

 to admit fresh air ; if this material point is neg- 

 lected, the consequence will be a green mossy 

 appearance on the surface of the earth, and a 

 universal mouldiness amongst the plants, which 

 will destroy them. It requires more skill to know 

 when and how long the pipings should be ex- 

 posed to the air, while forming root, than for 

 almost any other part of the management ; on 

 this single point, in great measure, depends the 

 good or ill success of the whole undertaking.
