graft to vigour and health, immediately becomes itself in- 

 fected with the disease. As all efforts totally to subdue it 

 must require a long course of time, th.e best method to pur- 

 sue towards its eventual eradication, is to stop its progress, 

 and prevent its farther extension to accomplish which, the 

 following means are recommended, which have been found 

 particularly successful. 



As soon as a tree is discovered to possess the characteris- 

 tics of the disease, which is generally known by the leaves 

 putting on a sickly yellow appearance but of which thp 

 premature ripening of the fruit is a decisive proof it should 

 be marked, so as to be removed the ensuing autumn, which 

 must be done without fail, for if left again to bloom, it would 

 impart the disease to many others in its vicinity ; care is also 

 necessary, in its removal, to take out all the roots of the dis- 

 eased tree, especially if another is to be planted in the same 

 place, so that the roots of the tree to be planted may not 

 conie in contact with any of those of the one which was 

 diseased. 



If your neighbour has trees infected with the yellows in a 

 quarter contiguous to yours, it will be necessary to prevail 

 on him to remove them, that yours may not be injured by 

 them. By being thus particular in speedily removing such 

 trees as may be infected, the disease is prevented from ex- 

 tending itself to the rest of the orchard, and the residue wiU 

 consequently be preserved in perfect health at the trifling 

 loss of a few trees annually from a large orcl

PEACHES, APRICOTS, AND 



ALMOND STOC 



In France a particular variety of the almond is used as a 

 stock on which to inoculate the different varieties of the 

 peach, apricot, nectarine, and cultivated almond. This va- 

 riety has now been introduced into cultivation in the author's 

 establishment, and trees budded thereon can be supplied in 

 the autumn of 1828. It is said that this almond is not subject 

 to the attacks of the worm ; and if so, it will furnish a pre- 

 ventive against these depredations which have been so great 

 a cause of complaint throughout our country. It is neces- 

 sary to observe, that this variety of almond is very different 

 from the common bitter almond frequently used for stocks 

 in the United States.
