to injure the roots. I only treated a few trees 
in this manner the first year, but I found it to 
answer well, and I afterwards went over all the 
Peach trees in the same manner. I have continued 
giving them a little fresh soil from old pastures 
every two or or three years since, always without 
any dung.” By adopting this plan for the last 
twenty years, he states that he has not had the least 
appearance of Mildew. 
Harrison’s Method. — “ Peach and Necta- 
rine trees are very frequently attacked by this 
disease, particularly so in low damp situations, be- 
cause in such there is generally stagnant water, 
at the bottom of the soil, w'hich is almost certain 
to produce the Mildew, without great attention has 
been paid to draining, &c. 
“ There are some kinds of Peach and Nec- 
tarine trees very subject to this disease, and in 
which it seems to be inherent, but it appears more 
or less according’ to the favourableness or un- 
favourableness of the situation in which the trees 
are planted, or as they may be affected by the wea- 
ther, which will also produce it ; for although a 
border be properly made and adapted to the trees, 
yet if very foggy weather continues for a few days, 
and the soil of the border is not in a state of 
moisture similar to that of the atmosphere, the 
trees will be generally attacked by the Mildew ; 
but when the weather is foggy, and the border is 
in a tolerably moist state, to the depth and extent 
to which the fibrous roots run, the trees will rarely
