Mr. Carpenter said that he had slit the bark of diseased trees 

 in the longest days in Summer, and they healed without injury, 

 and that was his remedy, for the disease. 



Andrew S. Fuller. — The bark of a healthy tree does not need 

 cutting — the disease that causes them to crack open, shows that 

 the bark is unhealthy and needs cleaning. There is something 

 about the kind of stock that cherries are growm upon. The 

 Mahaleb stock is a very bad sort to grow grafts upon, they will 

 almost always become diseased. I would never cut a tree to 

 cure the disease alluded to — I would clean off the moss and get 

 the bark smooth and healthy by other means, and thus cure it of 

 this and other diseases. Perhaps the difficulty all comes from 

 the graft out-growing the stock — then it is incurable. 



John Gr. Bergen. — Last Winter one of my cherry trees bursted 

 by frost. Now that is a sort of cracking open that cannot be 

 cured by slitting of bark, nor washing and cleaning it. 



Dr. Trimble. — This bursting of bark in Winter is easily account- 

 ed for ; but I can give no information about the disease spoken 

 of in the letter, but judge it must be, as it is in Winter, from 

 natural effects of contraction and expansion, and not by any dis- 

 ease. 



No remedy of easy application was given for the trouble spoken 

 of. The following is the letter alluded to, dated : 



"Belmont, N. Y., June 30, I860. 

 "Dear Sir : Will you allow me to ask of you or the 'Farmers' 

 Club,' if you know of auy remedy for the disease of Cherry Trees 

 in which the bark bursts, and is accompanied by a discharge of 

 gum. We have lost one valuable tree and several others are bad- 

 ly diseased. If you can give us any information, either by letter 

 or through The Tribune report of the Club, whereby we can save 

 them, you will greatly oblige 



" Yours very respectfully, 



" A. LANGDON." 



PRESERVING FENCE POSTS. 



Solon Robinson. — D. Edwards of Little Genesee wants to know 

 how to preserve fence posts from decay. After all that has been 

 said and printed how to do it, there are a few left that don't yet 

 know how, for Mr. Edwards proposes to do what will be more ex- 

 pensive than the right way. He says : 



" My posts are cherry, cut in the Winter j they are about 4 fee
