PEACH YELLOWS. 277 



lished the fact, with us. at least, that healthy fruit has been and can be grown upon 

 trees planted in the place where trees diseased with yellows have been removed. 



My first experience in this direction occurred the summer of 1874, when, in an 

 orchard of some four thousand trees, I discovered six trees of the Early Crawford 

 variety, all heavily laden with fruit and standing (luite near to each other, showing 

 unmistakable signs of yellows. A part of the fruit on each of these trees was spotted 

 with red spots, the red streaks extending from the surface to the pits. I had those 

 trees dug out at once and burned, and the following spring planted trees in tlie same 

 places. These trees came into bearing the third and fourth year from planting, and 

 produced fine, healthy peaches, and continued in so doing during the life of the trees. 



At the present time 1 have one tree that bore its first fruit last season, being lour 

 years old this spring from setting. The fruit was perfectly healthy. This tree was set 

 in the place of one taken out that had the wdry growth of wood, and had yellows, and 

 no mistake. 



From my own experience, and with quite extensive observation as commissioner of 

 yellows for four years, I am strongly inclined to the belief that where trees having 

 yellows are promptly removed and destroyed there need be but little cause for alarm 

 but what we shall be able to furnish healthv and fine peaches for many years vet. —

11. In reply to your first question, yes. For three years have been gathering peaches 

 from those reset. Those dug out bore the spotted fruit and had the wiry growth. 



2d. [When was it ?] In 1878— ten years ago. 



3d. [Under what circumstances ? 1 Condemned by the yellows commissioner. 



4th. [How many trees were thus reset ?] Three hundred. 



5th. 1 How long did these trees remain healthy?] Those reset are healthy to-day. 



6th. [What reason have you for thinking that the trees dug out were diseased with 

 yellows?] Because the fruit was spotted, insipid, and some of the trees had wiry 

 growth, and were condemned by the yellows commissioner. The three hundred trees 

 were taken out of an orchard of two thousand trees. 



I lost an orchard of five hundred trees, which I reset two years ago, and the trees are 

 doing well. — Robt. Reid. 



I made additional inquiries and Mr. Eeid replied as follows, under date 

 of April 26: 



In answer to your first question [How long after you dug out the three hundred 

 yellows trees before you reset ?] The next year, 1879. 



2d. [When you reset did you manure these trees or give them any other treatment 

 very different from the rest of the orchard ?] Used no manure, but put air-slaked lime 

 on all my orchard. Have manured since. The soil is gravelly — wheat soil. 



3d. [In the other orchard of five hundred trees destroyed by yellows, and reset two 

 years ago, how long a time intervened between the digging out and the resetting, i, e. , 

 what year did you dig them out and what reset ?] Three years. Dug out the last in 

 1883 ; reset in 1886. 



4th. [Have you used potash or any special fertilizer on the trees reset two years ago 

 in place of the five hundred, so that this might possibly account for their healthy 

 appearance ?J Have used air-slaked lime en them also. I followed, as near as I could, 

 the directions found in John Rutter's book on Peach Yellows.

12. I have trees growing, that were planted where trees having the yellows were 

 taken out, that have borne healthy fruit three years and show no signs of disease. — 

 James F. Taylor. 



Finally, the recent admission by Professor Penhallow that restored trees 

 are liable to a relapse; the statement by Henry Eace, of Pittstown, K". J., 

 that trees can be reclaimed only when the disease is in an "incipient" 

 state; the statement by Charles Black, of Hightstown, N. J., that badly dis- 

 eased trees cannot be cured, and the universal New Jersey practice of remov- 

 ing diseased orchards when they are only six or eight years old, would seem 

 to warrant the belief that the potash and phosphate treatment, which has 

 been most vigorously championed in that State, does not really cure peach 

 yellows, or even prevent it.
