34 PEACH YELLOWS. 



(13) August 10, 1888. Variety, Reeves' Favorite. One limb was removed; two 

 limbs were left. The excised limb bore about a dozen large, ripe peaches and more 

 than one hundred green ones. There were no diseased shoots; the foliage was full 

 grown and vigorous and the stump was sound. The remaining limbs bore healthy, 

 green peaches and excellent foliage. 



May 13, 1889. Apparently diseased, i. e. } there are a few feeble shoots on the trunk, 

 but it is too early in the growing season to decide positively. One large limb was 

 blown away by the tornado. 



September 17, 1889. Still diseased. There are a few sickly shoots on the base of 

 the trunk below the excision, but some robust, healthy-looking shoots also grow from 

 the vicinity. Diseased shoots also grow from beneath the base of the limb which 

 was blown away by the tornado. The crown of the tree still bears full-grown, dark- 

 green foliage, but on one branch some of it curls and droops a little. There are no 

 other signs of disease. No fruit this year. 



October 11, 1890. The tree is well provided with good-looking foliage, but diseased 

 sprouts have grown from the base of the trunk, and many winter buds are now ger- 

 minating. No fruit. 



(14) August 10, 1888. Variety, Old Mixon. Two limbs were removed, i.e., about 

 two-thirds of the whole top ; and two were left. One of the excised limbs was loaded 

 with peaches which were ripe, and red-spotted on the skin and in the flesh. The 

 other limb bi parted one foot above the cut. The larger fork was loaded with ripe 

 peaches; the smaller one bore many green peaches and only a few premature ones. 

 This smaller fork had lost a branch and was dozy at the heart from that point down- 

 ward for a distance of 3 feet, rain having entered. One stump was sound ; the other 

 showed two small dozy spots in the center, the result of the downward movement of 

 the decay which began at the base of the broken branch. There were no diseased 

 shoots and the foliage was healthy. The remaining limbs were healthy, i. e., seemed 

 to be. The peaches were green, and the foliage was excellent. I mention condition 

 of stumps because yellows has been attributed to injuries. In this connection it may 

 be noted that these trees were covered with smooth, sound bark and were very free 

 from injuries of any sort on any part, limbs, trunk, or roots. The entire orchard has 

 escaped the attacks of the borer (^Egeria) to a remarkable degree. Most of the trees 

 used in this experiment were entirely free from them and hud always been so while 

 none of them had been seriously injured. Possibly the character of the soil has had 

 something to do with this immunity. I find this insect most troublesome upon sandy 

 or friable soils. On the light sands of Sussex and Caroline Counties the borers have 

 to be removed onco a year and sometimes twice. Otherwise the orchards would soon 

 be destroyed. 



May 13, 1889. Apparently still diseased. The suspicious appearances are upon the 

 trunk near where the limbs were removed. 



September 17, 1889. Still diseased. Six inches below the lowest excision there is 

 a feeble, much-branched yellows shoot. The smaller limb was blown away by the 

 tornado. The remaining limb is now plainly diseased. Its spring foliage is full 

 grown, but lighter green than should be, and is somewhat inclined to droop and curl. 

 There are also well-marked, feeble yellows shoots on several branches at distances of 

 8 to 10 feet from the excision. No fruit. 



October 11, 1890. Most of the foliage has fallen; what remains is abnormally reddish. 

 The tree is twiggy, and there are signs of disease in the top. One stem shoot also 

 bears fifteen buds, which have germinated recently. No fruit this year. 



(15) August 10, 1888. Variety, Christiana. Two limbs were removed, both from 

 one side ; one limb was left. Nearly all of the fruit on both of the excised limbs was 

 premature ; on both limbs 3 feet above the cut diseased shoots had pushed through 

 the rough bark, but were only from one-half inch to 2 inches long. On one of the 

 limbs at the same height there were also stout, healthy-looking shoots of this season's 

 growth. The other limb bore an additional 15 or 20 feeble shoots 5 to 8 feet above the
