18 STATE POMOLOGICAL SOCIETY. 



his mental consideratioo. He stated that the glands would not relieve peaches 

 from the Yellows at all. The Yellows is a disease which attacks all classes of 

 peaches alike. It attacks peaches with glands as well as those without. It ia 

 analagous to the yellow fever, which attacks with equal virulence all races of 

 men ; black, white, copper colored, and yellow." 



A gentleman commenting upon these remarks of Mr. Prince, says : " Some 

 might suppose that Mr. Prince wished to convey the idea that the stinted, 

 sickly appearance of peach trees with glandless leaves, was owing to an inher- 

 ent or constitutional disease in such trees from tlieir earliest vegetation. I do 

 not think that Mr. Prince intended to be so understood ; if he did, I think it 

 would be difficult to defend his position." 



That the character of the plant is early determined, even from the time of 

 the impregnation of the flower, from which the seed is produced, I believe is 

 now conceded by our best vegetable physiologists. 



That the constitutional character thus formed may be impaired by disease at 

 anytime during the life of the plant, is self-evident; but diseases thus pro- 

 duced, and those that are constitutional, should be considered separately. 



That those varieties of the peach, whose leaves are destitute of glands, are 

 more subject to what is termed IJight or mildeiv on the young shoots in the 

 afterpart of summer has long been noticed; but as the mildew does not make 

 annual appearance ujion the peach tree until after the young fruit is formed, 

 and its character, so far as the young plant to be produced from the seed is 

 determined, we cannot conceive how this mildew, which is nothing more than 

 a fungus plant, uncongenial in its growth by circumstances attending its 

 locality, can have anything to do with forming a constitutional disease, and 

 should therefore be considered an accidental injury, which, although it retards 

 the growth of the young shoots after it fixes upon the tree, does not appear to 

 injure the wood formed before the mildew makes its appearance. Trees of this 

 description, although they do not extend their branches quite as rapidly as 

 those having glands, are often as long-lived as any glandular varieties. 



There are some serious objections, however, to many of the serrated varieties, 

 as the Early Tillotson and some others, as on these varieties the mildew extends 

 to the fruit, covering the skin with unsightly spots, and causing it to rot 

 prematurely upon the tree. 



A. J. Downing says: " It is well worth remarking that certain fine old sorts, 

 the ends of the branches of which have a peculiar mildewed appearance (such 

 as the old Red Eareripe, the Early Anne, etc.), which seems to check the 

 growth Avithout impairing the health, are rarely if ever attacked by the Yellov/s. 

 Slow growing and moderately productive sorts, like the Xutmeg Peaches, aro 

 almost entirely exempt." 



QUESTION NO. 9. 

 9. Does the disease that is now affecting the peach trees in your vicinity, if any, attack 

 both serrated and glandular leaved varieties alike, or do you find that one resists tjie attack 

 more persistently tban the other? 



The remarks just made will show that the subject matter contained in ques- 

 tions No. 8 and 9 is a very interesting and important one to peach growers ; they 

 also show the relevancy of the questions to the subject under consideration by 

 the committee. 



QUESTION NO. 10. 

 11. What is the character of the soil at your place? 



It is possible that the character of the soil may have something to do with 

 the origin and spread of the disease. Of course it is a very important question.
