Waite suggested the wisdom of spraying to control this disease, and also 

 the propriety of top grafting tender varieties on the trunks of immune 

 sorts. 



Thus far Mr. Paddock has not ventured any practical application of 

 his discoveries; but it is plain that they are likely to be of considerable 

 consequence to fruit-growers. The apple canker appears to be doing a 

 deplorable amount of damage, even though in many cases it was hardly 

 suspected. This damage can apparently be diminished by spraying in- 

 telligently directed against it. Many orchardists have already noted that 

 careful spraying helps the health of their trees; and now they may per- 

 haps soon be given a nevr motive and a new reason for spraying, with new 

 directions for meeting a new enemy. These preliminary notes on apple 

 canker seems to us to be of unusual importance. — From Country Gentle-

CEDAE APPLE FUXGUS. 



Professor J. C. "Whitten, Columbia, Mo. 



Dear Sir: — I was called to Conway, in the western part of this 

 county, to examine an orchard in which were found the diseased twigs 

 which I enclose to you. "What is the disease and what the prevention? 

 It looks as if the trees would l)e seriouslv damaged, if not destroved, if a 

 remedy is not applied. These twigs came from an old York state variety, 

 the Twenty ounce apple. A Rome Beauty and these two Twenty ounce 

 apple trees are in the same condition. Have your report of the disease or 

 trouble published in the ''Pural World." — A. iS^elson, Laclede Co., Mo. 



Editor "Pural AVorld:" Specimens of apple leaves have just been 

 received that are very badly infested with a peculiar disease. The upper 

 surfaces of the leaves are badlv discolored bv orauii'e colored blotches 

 one-eighth to one-half inch in diameter. These blotches sometimes be- 

 come almost scarlet and the leaf seems to be entirely dead in the vicinity 

 of each l)lotcli. The under side of each blotch looks scurfy and produces 

 small warty horns oiie-sixteentli of an iiie'li long, closely clustered to- 

 gether.
