THE PLEASURE (i ROUND. 281 



the size of which should be regulated by the pots, 

 and be occasionally wiped, when there appears an 

 accumulation of moisture on their inner surface ; 

 but these glasses may consist of those with holes in 

 their tops, which will permit the moisture to evapo- 

 rate, and prevent it, in a great measure, from injuring 

 the cuttings. Mr. M'Nab, however, and the Messrs. 

 Loddiges, both consider these glasses unnecessary, 

 except for a few sorts. When the cuttings begin to 

 grow freely, it is generally a sure sign of their having 

 made roots ; they should then be taken carefully out, 

 and put into the smallest sized pots that are made, 

 placing four or five round the sides of each, and then 

 placed under a hand-glass, and shaded, until they 

 begin to make young roots in the fresh soil, when they 

 may be gradually exposed to the sun and air ; and 

 when they appear to be of sufficient strength, and 

 their roots well established in the soil, they should 

 be planted singly into small pots, and afterwards 

 treated in every respect the same as was mentioned 

 for the seedlings. 



The culture of the Ericece is rendered more easy 

 by their being seldom attacked with insects; the 

 green fly will occasionally infest some of the plants, 

 but it is easily eradicated by fumigation, or by dip- 

 ping the infected shoots into a decoction of tobacco- 

 water ; some of the species are, also, subject to mil- 

 dew ; but this is likewise readily subdued, by dusting 

 a little sulphur over the affected parts; the most 

 effectual preventive for the latter disease, however, 

 is a free circulation of air amongst the plants.
