58 PEACH ROSETTE. 



mal shoot axis. Such trees generally die in the summer or autumn 

 of the same year ; Fig. 2, healthy budded tree of same age from 

 the same orchard. It might have been only 20 feet distant. Photos. ' 

 June 3, 1891, Griffin, Ga. Trees about 14 feet high. Part of the left 

 side of each photo is omitted to bring it within the requirements of 

 the plate. 



XXX. Terminal branches from a budded tree of bearing age. Fig. 1, still per- 

 fectly healthy to all outward appearances. Fig. 2, in first stages 

 of the rosette ; Fig. 3, com plete, typical rosette , All from the same 

 tree. Reduced to about one-seventh natural size. Photos. July 5, 



1890, Griffin, Ga. 



XXXI, XXXII. Shoots from a seedling tree of bearing age showing progressive stages 

 of the rosette from appearance of perfect health to complete dis- 

 ease. Fig. 1., perfectly healthy and very thrifty. Foliage smooth 

 and green. Fig. 2, leaves commencing to roll, straighten, and 

 become yellowish ; Fig. 3, spring foliage worse diseased than in 

 Fig. 2, and yellowish, rolled, and somewhat injured on the margin 

 by leaf fungi. The winter buds on the upper part of the shoots 

 are unfolding into rosettes. Fig. 4, rosettes developing and fully 

 developed. Photos. July 2, 1890. Tree found in a thicket at Sunny 

 Side, Ga. Reduced to about one-fourth natural size. 



XXXIII. Fruit from diseased and healthy looking side of an affected tree. 



Fig. 1 from a badly resetted branch. The foliage of this twig was 

 yellowish, and its buds had begun to push into rosettes both above 

 and below the fruit, which was yellowish green and had begun to 

 shrivel slightly but was not strikingly different from Fig. 2. Fig. 2 

 healthy twig and green, half-grown fruits from same tree* Photo.

INOCULATION EXPEEIMENT No. 1. 



XXXIV. First results, year 1890. Two of the worst affected trees. Time, 4 



months and 12 days from date of insertion of the diseased buds. In. 

 both figures the bits of white paper indicate the location of these 

 buds. In Fig. 1 both buds united with the stocks, but neither one 

 pushed, the nearest diseased shoot being from the stock. In Fig. 2 

 the lower bud grew into x, while the upper bud did not push. In 

 Fig. 2 the base of the uppermost diseased shoot was 5 inches 

 above the uppermost inserted bud. The left side of each tree ap- 

 peared to be perfectly healthy. Inoculations June 21, 1890. Photo* 

 November 3, 1890, Griffin, Ga. 



XXXV* Year 1891* Row of seedling trees inoculated June 21, 1890. Photo. 

 June 6, 1891, Griffin, Ga* All diseased throughout and left one 

 drying up. The diseased buds were inserted near the earth and the 

 seedling tops were not removed. 



XXXVI. Year 1891. Trees inoculated June 21, 1890. Fig. 1, healthy seedling, 

 two buds were inserted, but failed to heal on. Fig. 2, seedling dis- 

 eased in all parts; one or both of the buds healed on. Photo. June 

 6, 1891, Griffin, Ga. 



XXXVII. Year 1891. Fig. 1, several trees inoculated June 21, 1890, and now 

 diseased in all parts; Fig. 2, two healthy seedlings inoculated 

 with healthy Elberta buds about the same date. Photo. June 6,

 seedlings diseased by the rosette as the result of inoculations made 

 June 21, 1890. Part II bird's>eye view of adjoining healthy nursery 

 of Elberta. Photos. June 6, 1891, Griffin, Ga.
