tree dies within a year after it shows its first symptoms, though in a few 

 instances trees partly attacked in spring show leaves again next spring. 

 Trees attacked during the summer and fall show the symptoms by the 

 pushing of winter buds that should remain dormant. In an experiment 

 with bud inoculation, out of 125 trees budded from a diseased tree, 121 

 showed rosette within a year; the buds inserted on the four remaining 

 healthy did not ''take." The native plums, Primus Americana., Prunus 

 Chicasa, and the introduced Japanese plums, such as Kelsey, show a very 

 similar disease, and experiments are now in progress to determine 

 positively whether the diseases are identical. 



In some portions of Georgia the effects of the disease, as evidenced in 

 the orchards, are as disastrous as the effects of yellows in Maryland and 

 Delaware. So far as is now known, the disease first appeared some five or 

 six years ago in Georgia and about three years ago in Kansas. It is a 

 serious menace to the southern peach-growers, only less dangerous than 

 yellows because of the fact that the fruit does not reach the market and so 

 does not damage the sale of healthy fruit, as was the case this year in the 

 markets of our eastern cities. The cause is not yet determined, but there 

 is every reason to believe that the continued and well directed work of the 

 division will eventually discover it and after that a remedy or preventive- 

 Till then the axe and fire are the only safeguard." 



CONCERNING YELLOWS. 



Mr. Taylor was asked, Are the people in Delaware enforcing their 

 yellows law? and replied: The Delaware legislature passed a local act. 

 not covering the part of the state where yellows most prevails, and even 

 in the section it covers it is only partly enforced. They are not as 

 thorough in cutting the trees as they are in Michigan. Development of 

 yellows was greater this year than usual in Delaware and Maryland, in 

 some orchards affecting 60 per cent, of the trees. Its greatest develop- 

 ment was in the young orchards in the mountain regions of western Mary- 

 land, where all conditions for growth of the peach are favorable. 



Mr. Alexander Hamilton of Ganges: There is a difference of opinion 

 and practice in my vicinity as to the cutting of peach trees diseased with 

 yellows. Some contend that they should be cut, uprooted, and burned at 

 once, utterly destroyed; while others believe that it is sufficient to cut and 

 leave the tree, afterward either drawing it out or burning where it stood. 

 The Ganges commissioners permit the latter, while Mr. Wiley of Sauga- 

 tuck township requires immediate destruction. Mr. Smith should be 

 accepted as authority upon the matter. 



Mr. J. N. Stearns of Kalamazoo: If no growth ensues from the old 

 stump, there is no danger from leaving the cut tree in the orchard till 

 some convenient time for removal. 



Mr. K. Morrill of Benton Harbor: There should be no dallying with 

 yellows. Rather than carry out the diseased trees at any time. I would 

 burn them at once upon cutting.
