PEACH YELLOWS AND PEACH ROSETTE. 177 



Result. — August 17, 1888. The tree is now full of fruit and at least one half of it 

 is premature. The diseased peaches are not confined to any special part but are borne 

 on all of the main limbs. There are also characteristic, feeble shoots on the trunk. 



(6) September 15, 1887. Variety, Beers' Smock. A large tree. One limb was 

 removed, four were left. 



Result.— August 17, 1888. Two of the four limbs bear green, healthy peaches; and 

 two bear premature ones, far out toward the ends of the branches. Diseased shoots 

 have also grown from the base of these two limbs and from the trunk below the excised 

 limb. There are a few green peaches on the prematured limbs. 



(7) September 15, 1887. Variety, Wilkins' Cling. Two limbs were removed, three 

 were left. 



Result. — August 17, 1888. One limb is sound, f. e., no symptoms have developed. 

 The other two bear mixed fruit; on some branches it is premature and now fully ripe, 

 on others it is healthy and still green. Both limbs bear branched and very character- 

 istic yellow shoots. 



(8) September 15, 1887. Variety, Wilkins' Cling. One branch was removed from a 

 large limb. The remainder of this limb and three other limbs were left. 



Result. — August 17, 1888. One limb bears green, healthy peaches; the others bear 

 prematurely ripe fruit and branched and unbranched yellows shoots. But some branches 

 bear sound peaches. The limb from which the branch was removed is not worse affected 

 than another on the opposite side of the tree. 



(9) September 15, 1887. Variety, Wilkins' Cling. One small limb was removed; 

 three larger ones were left. 



Result. — August 17, 1888. Most of the peaches on this tree are green and healthy 

 bit branches upon two of the three limbs bear ripe red-spotted peaches and the diseased 

 shoots. 



(10) September 15, 1887. Variety, Beers' Smock. One limb was removed; three 

 limbs were left. 



Result. — August 17, 1888. There are many premature peaches on all parts of the 

 tree, but some of the branches still bear green ones. There are no sickly shoots. 



(11) September 17, 1887. Variety, Crawford's Late. One limb was removed, three 

 were left. 



Result. — August 17, 1888. Most of this tree is healthy, i. e., appears to be. Two 

 branches of one limb only bear premature, ripe fruit, and small feeble shoots. A large 

 branched shoot, very typical of yellows, has also grown from the body below the excised 

 limb. 



(12) September 17, 1837. Variety, Crawford's Late. Two limbs were removed; three 

 were left. 



Result. — August 17, 1888. There are premature peaches and characteristic yellows 

 shoots on every main limb. Some of the branches on these limbs also bear green, 

 healthy fruit. 



(13) September 17, 1887. Variety, Oldmixon. One limb was removed; three were 

 left. 



Result. — August 17, 1888. Most of the tree bears green, healthy peaches. One 

 limb, however, bears nothing but ripe prematures. A small branch on another limb 

 also bears this kind of fruit. The sickly shoots have developed on both and on the 

 trunk below the excised limb. 



(14) September 17, 1887. Variety, Oldmixon. Two limbs were removed; three were 

 left. 



Result. — August 17, 1888. All of the main limbs bear premature peaches and diseased 

 shoots. There are also two much-branched, yellows shoots on the trunk — one below 

 the excised limbs and one on the opposite side. The tree still bears some green, healthy 

 peaches. 



(15) September 17, 1887. Variety, Stump-the- World. One limb was removed; three 

 were left. 



Result. — August 17, 1888. One limb bears green, healthy peaches. The other two 

 bear mixed fruit, i. e., premature, fully ripe peaches on some branches and immature 

 normal ones on other branches. There are no diseased shoots. One small branch on 

 this tree bears premature peaches upon three twigs, and green peaches upon two others. 

 One of the latter is three inches and the other is fourteen inches below the lowest twig 

 bearing the prematures. The foliage and bark on this branch appear to be perfectly 

 normal, and I can see no difference between the twigs bearing sound peaches and those 

 bearing diseased ones. 



(16) September 17, 1887. Variety, Stump-the-World. One limb was removed ; three 

 were left. 



Result. — August 17, 1888. This tree bears a great quantity of fruit and only a very
