dency to increase the growth and vigour of the tree. 

 If in arty of the uncovered branches black spots or 

 oozing of gum should be discovered, let the branches 

 be immediately cut away, and the wound covered 

 with the same composition, and young shoots will 

 soon sprout forth and bear fruit. When peach trees 

 have become unproductive from old age or disease, 

 Mr. Forsyth, from long experience, recommends to 

 head them down according to rule, and apply the 

 composition, by means of which, trees in the worst 

 condition may be completely renovated, and render- 

 ed abundantly fruitful. Hitherto, the diseases of peach 

 trees among us have eluded all our art and skill : how 

 far a different management may prove successful, time 

 and experience must determine. It may, however, 

 well be questioned whether it is most profitable to re- 

 new our stock by frequently planting the seed, or to 

 attempt to protract the existence of old unproductive 

 trees by the application of remedies. 



Since writing the above, the following fact has been 

 announced in the newspapers of New York. A very 

 simple mode of preserving and restoring peach trees 

 when apparently nearly destroyed by the disease so 

 fatal to them in this quarter, and commonly called 

 the ^yellows" has been accidentally discovered by a 

 gentleman in that city. A statement of the fact, as 

 it occurred, will convey all necessary information. 

 In the fall of 1818, a very fine tree standing in his 

 yard, was apparently dead from the effects of the 

 above mentioned disease. Throughout the fall and 

 winter, very large quantities of common wood ashes 

 were casually thrown by the servants about the roots 

 of the tree. To the astonishment of all who had seen 

 it the preceding fall, it put forth its leaves vigorously 

 the next season and bore abundance of fine fruit. A 

 small quantity of ashes was again thrown round its 

 roots last fail, and the tree has now become so full of
