EXCISIONS AND RESULTS. 33 



bore 20 to 30 green peaches and about the same nurubei of fully-ripe ones,* but none of 

 the latter were within 10 feet of the cut. There were no diseased sprouts or ger- 

 minating winter buds. The foliage was full grown and entirely healthy. The 

 remaining limbs bore healthy peaches and excellent foliage. One small shoot, how- 

 ever, on the base of the east branch, did not appear quite right, yet I could not say 

 it was affected by yellows. It was 14 inches long and unbranched. The leaves 

 were somewhat paler than normal and were attacked by a shot-hole fungus, which 

 is quite common on the leaves of diseased trees. 



May 13, 1889. The enlire top was blown away by a tornado which occurred soon 

 after the excision, but the stubs of the limbs appear to be diseased. 



September 17, 1889. Numerous yellowish, much-branched, feeble, spindling shoots 

 have grown from the stub. 



October 11, 1890. The trunk is now dead. 



(11) August 10, 1888. Variety, Reeves' Favorite. One limb was removed. This 

 subdivided 2$ feet above the cut into four branches, three of which bore a few 

 large, ripe peaches, while the fourth bore about twenty green ones. The proper time 

 for the ripening of this variety in that orchard is August 20. The foliage was full 

 grown and healthy looking, and there were no diseased shoots either from winter 

 buds or obscure buds.t The stump was sound. The remaining limbs bore healthy, 

 green peaches and excellent foliage. There was no sign of yellows. 



May 13, 1889. The entire top was blown away by the tornado. There are no vigor- 

 ous shoots on the trunk or stubs of the limbs, but only three or four buds pushing 

 feebly and two small, dried-up shoots. The stump looks nearly dead, but this is 

 probably due in part to the effect of the wind. 



September 17, 1889. Dead. No growth of any sort since spring. 



(12) August 10, 1888. Variety, Reeves' Favorite. One limb was removed. This 

 bore about twenty large, showy, ripe peaches, and about the same number of much 

 smaller green ones all of the latter upon one branch. There were no diseased 

 shoots; the foliage was healthy; and the stump was sound. The remaining limbs 

 appeared to be healthy. They bore green peaches-and vigorous foliage. 



May 13, 1889. Doubtful ; a feeble shoot is pushing just beneath the stub of the ex- 

 cised limb. 



September 17, 1889. The tree is diseased, but the symptoms are slight and confined 

 to the trunk. There is a diseased shoot 6 inches below the excision, and another 

 stouter one on the margin of the cut. The winter buds upon the latter are now 

 germinating. The foliage of the entire top looks healthy and is vigorous for the 

 time of year. Had these two shoots been removed prior to examination, or had they 

 never grown, any one would have pronounced the tree entirely healthy. 



October 11, 1890. Still diseased. Most of the foliage has fallen ; what remains is 

 abnormally reddish. Numerous winter buds are now germinating upon two shoots. 



*The premature peaches on this tree, like those on all the others, were large and 

 showy; the skin was red-spotted and high colored ; the flesh was also much streaked 

 and spotted with bright red. Many of these spots were to be seen on radial as well as 

 tangential sections. They were about one-sixteenth inch in diameter, and were not 

 confined to the nbro-vascular system, but formed part of the ordinary parenchyma 

 of the fruit. The streaks of color were limited principally to radial sections, but did 

 not extend from from pit to skin. Some of these peaches tasted very well ; others 

 were insipid or sickish. Sometimes, even, one-half ot a peach tasted well and the 

 remainder was not palatable. 



t Upon the diseased trees in this orchard there were fewer yellows shoots in 1888 

 than in 1887. This was also true for all the other orchards in that region. It was 

 correlated with dry weather, which also had its effect upon the total growth. At 

 least, in this orchard, where I examined most particularly, the healthy terminal 

 growths of 1888 were considerably shorter than those of 1887. There have been 

 rather more cases, however, in the dry seasons than in the wet ones.
