APPLES. 105 



Both of these lists might be greatly enlarged were there more data 

 at hand. It is evident from the reports thus far compiled that very 

 few, if any, of the eighty-one varieties named are entirely free from 

 the disease under all conditions. Again, there are some generally 

 reported as " bad blighters " that appear in the list of " least affected." 

 These facts indicate the possibility of so controlling the growth of 

 the tree that it may successfully resist the attack of the blight 

 bacteria. 



Third Question.— What do you do to check the twig blight? 



CUT AND BURN. 



In answer to this question there were twenty-one correspondents 

 who "cut out and burned the blighted parts, thus controlling the 

 disease with fair success." There were three who also "cut out and 

 burned the bad blighters." There were three who, "in addition to 

 the destruction of blighted parts and bad blighters, also stopped 

 cultivation and seeded to clover." Two correspondents said "cut out 

 and burn the blighted parts when the trees are through blighting." 



SPRAYING. 



There were three correspondents who used spraying mixtures, 

 two "with no success" and one who did not say whether successful 

 or not. 



ROOT-PRUNING. 



Root-pruning is said by one correspondent to have been "success- 

 ful in checking blight in Talman Sweet in the orchard." Another 

 correspondent "root-pruned in the nursery row." 



SALT AND LIME. 

 One correspondent used a liberal application of "salt and liine to 

 the surface of the soil." Another used "lime, ashes and manure." 



NOTHING. 

 Six correspondents did nothing, and seven gave us answers to this 

 question. 



Fourth Question. — Have yovx noticed anything in regard to lo- 

 cality, slope, altitude, protection, soil, etc., that favors or checks the 

 disease?
