times it may l)c' two years beloi-e it spreads to any great extent. It 

 is generally conceded to be contagious, allliongli some jieople claim 

 that it is not. The curl-leaf frequently occurs after a cold sjiell as 

 a .swelling of the veins. 



Mr. (r /-ay, of California — We have a disease which some have 

 th(»u<rht to be vellows. Examination shows the roots to be first 

 affected, jelly-like lumps appearing at the surface of the ground. It 

 .seems to be contagious. 



Major Evaiift, of Missouri — The yellows seems not to have crcssed 

 the Mississippi river. The curl-leaf may be cureil by removing the 

 earth about the trunk of the tree and filling the basin with hot lye. 



Major Hohinger — In case of the true yellows the exudation of 

 gum takes place along the main branches and not at the collar. I 

 susjH'ct Mr. Gray's trees are affected with the ])each tree borer. 



Mr. Gray — The disease I referred to appears to be a fungus, 

 and not the work of a borer. 



Mr. Goodman, of Missouri — The yellows is contagious under 

 certain circumstances. In Michigan the application of wood ashes 

 is claimed to be a remedy. 



Mr. Sweet, of Ohio — The yellows exists in Ohio, and it is not 

 cured by ashes, either. The only sure remedy is to make ashes of 

 the diseased trees and use them as a fertilizer for other trees. It is 

 a fatal contagious disease, and I advise California fruit-growers to 

 exterminate the diseased trees on the first appearance" of the yellows. 



Mr. ]Vatson, of Oregon — The j)each is a favorite fruit and is 

 valuable in many portions of Oregon. Ilie peaeh-growing interest 

 is now growing i"aj)idly. A fungus blight sometimes destroys our 

 croj)s. I have j)roduced from four acres of Early Crawfords 1,6U4 

 twenty-pound boxes of fruit, which sold for an average of $7oO per 

 acre. The best time for pruning in Oregon is just after the fruit is 

 gathered. Severe winters are our greatest enemy. 



Mr. Jhuld, of New Jersey — Our peaeli interest has sulfered 

 greatly in New Jersey from the yellows. The best remedy known 

 to our people is tlie applieatiim of nuiriate of j)()tash. 



Mr. Stevens, of Texas — Wood ashes is thought to be a remedy 

 for the yellows in Texas, but we are not really sure that we have 

 the true yellows. The disease we have seems to be a root blight. 



On motion, the Society adjoiiincd to meet at 9 a. m. to-morrow.
