PROCEEDINGS OF THE FARMERS' CLUR. 91 



Mr, Tn'pol toUl mo tliat lie liist ohscrvtMl tlio disease last j'car poiva<ling' 

 the (lifkTiMit vari(>ti(>s niltivatcMl tinder f^Iass inoiu! or loss — tlio wliito vario- 

 tips cvidoncinp the ollrot iiu ro readily and soMHildy tlian the more liardy 

 colored varieties jj^onerally. One vine of HIack Harl)arosa, a vig-(;ronH and 

 rampant <;r<>wer, appeared more injured tlian any other in the collectioi), 

 and he oonelnded to try the experiment of cntting' back and forcing new 

 wood from near the root that he might test its eirocts on the new growth. 



The resnit is as ho showed me, the growth of vine was really strong and 

 even rampant, reaching in length from 18 to 20 feet, it exhihitod tiie rav- 

 ages of the dist'ase as much or niori; than any (.)tlier vine in the grapery. 



Mr. 'I'riplc's conclusion is, llial it is a fiingns, and during tlie present 

 .season, it iias shown itself upon all the varieties grown on the grounds of 

 Mr. liovering, including the most hardy natives, and those both grown 

 under glass and in the open air. Tiie more delicate varieties exhibit 

 greater sensibility and more fatal n.'.^ults, tlian the native or more hardy 

 foreign varieties. 



He thinks the disease is much extended from last year, and tliat it per- 

 vades the root as well as the vine, as evidenced from the experiment which 

 I have described. Mr. Triph; assured me that Mr. Levering as well as 

 himself are much interested in the investigation of the subject, and would 

 be happy to add any further knowledge, that their ( xpcrience may enable 

 them to aid the eflbrts of the Association to ascertain its cause and remedy. 

 My observation in the neigliborhood of Philadelphia satisfies me that the 

 disease is very general, and that the efiects this year will result in a very 

 short ancl inferior crop of fruit. 



The query is, is it climatic or constituiioiial ? 



Mr. John G. Bergen — This is an impotant subject, and I hope the mem- 

 l>ers will give us the results of their observations. 



The dry .season this year has been very favorable to the grape. I shall 



fruit more than fifty varieties of native grapes. I have not found any 



'^ym|)toma (>f rot in any of the varieties so far. I tiiink it requires the 



xprricnce of several years to make up an opinion as to the value of these 



varieties. 



Mr. J. Iv. Lancaster, Quakertown, Berks (Jo., Fa., writes as follows : I 

 acknowledge an indebtedness to the Farmers' Chib for nuuh valu;iblc 

 infr»rmation. I take the liberty of asking whelher the members know if 

 I)elaware and Diana grape can be made into raisins. 



At a recent njccting, Mr. S. 0. Cross suggests a theory on planting fruit 

 trees to prevent sun or frozen sap blight. As the fall season is approach- 

 ing, I take the liberty to suggest a mode of transplanting I have; prac- 

 tised for the last fifteen years in a small way (aUhough I prefer the spring 

 to the fall for transplanting). I select my trees in the nursery, and mark 

 the south side of them. I take care to preserve all the roots I can. I 

 prepare the ground so as to receive them in their original position, the 

 Bame as they stood in the nursery, for the reason that nature's laws are 

 generally .self-evident. Those who will take the trouble to satisfy them- 

 selves on the subject will be convinced of the fact that there is a dinVrencc 

 in the texture of the wood of the body of the tree on the north and south 

 sides. If we change the position, we chatige the natural growth of the
