ON COVERING FRUIT TREES. 
BY H. C. 
In Number XLIII. of the Horticultural Register , I observe in a 
communication by Mr. William Grey, he seems to think the trees 
under Mr. Eaton’s care are not benefited by the covering he has 
adopted. I think, on the contrary, that they are of great use ; for 
while the wall-trees at most places round here are in a sad state of 
blight, his have the most healthy appearance; are neither blighted, 
mildewed, or cankered; they have had the same treatment they used 
to have previously to his having the curtain; and many of them are 
growing in the same soil that those did which died in the cankered 
state he mentions in his communication. 
Being a young gardener, and wishing for information, I should be 
obliged to Mr. Grey, or any other correspondent, if they will inform 
me, through the medium of the Register, what it is that causes the 
marked difference in his trees, if it be not the covering? 
In the place I am now living at, we have adopted the same sort of 
covering for some tender exotics, which we planted against the open 
wall last autumn ; but not having much frost last winter, with the 
exception of a night or two (the thermometer indicated 14° of frost on 
the 20th of January), I am unable to say if they will afford that pro¬ 
tection which they require. 
I am sorry to see you discontinue the account of new plants figured in 
the different periodicals : I hope you will resume the account, as many 
besides myself consider it one of the most useful portions of the 
Horticultural Register.

My opinion has been requested on the following subject, and the 
queries which are annexed :— 
“ It has been long ago discovered, that strong soap-lather applied to 
the leaves or shoots of plants infected with the fungus called mil¬ 
dew, destroys that parasite, and restores the plant.
