Prof. H. H. Whetzel, of Cornell University, N. Y. gave a stereop- 

 tican lecture on a new light upon apple blight. He claimed that 

 blight is a bacterial disease and is not due to fungi. He designates 

 blight as blight canker, and gave us many illustrations of its eflfect 

 on limbs, body and trunk of the trees and on the foliage, what he 

 called "mouse-eared" in appearance. Affected trees blossom heavily, 

 setting more fruit than the tree can mature. Indications are brown 

 streaks in the bark and collar rot, seamy blisters, etc. There are 

 five kinds of canker blight, always black. A remedial wash for dis- 

 infecting scabby spots on trunks and larger limbs is two-tenths per 

 cent corrosive sublimate and six lbs. blue vitrol in fifty gals, of 

 water, cleaning away all dead and affected bark and using as a paint. 

 He had been making a study of varieties susceptible of blight and 

 those that had been more immune. Some varieties were more re- 

 sistant than others. In one orchard, out of two hundred trees only 

 seven trees remained alive. He recommended to always top-work 

 on non-blighting varieties. He named Wolf River as immune, and 

 the Baldwin as very susceptible to canker blight. Those seeking 

 further information on blight should send to Cornell University for 

 the bulletin on blight. 



There were several other subjects of interest discussed but time 

 and space will not permit of reporting it at this time. I will try to 

 say something at the winter meeting on the new method of grafting 

 and give a short outline of my six days' trip through the Ozark 

 fruit belt of northwestern Arkansas and southwestern Missouri. 



MY EXPERIENCE WITH SEEDLING PLUMS. 



G. A. IVINS, IOWA FALLS, IOWA. 



(From the "Fruitman.") 

 The fruiting season of some thirty-five or forty seedling plums 

 the past year gave promise of a number that are superior to their 

 parents, some varieties showing a marked difference from the 

 parent, while others were almost identically the same in size, color 

 or quality of fruit. In this respect the Stoddard seedlings bore 

 fruit almost exactly the same as its parent, but in tree and foliage 

 there was a perceptible difference. The four Stoddard seedlings 

 that bore their first crop of fruit the past season were a grand sight 

 to behold. Each tree was bending to the ground with its load of 

 fruit, and every time we picked we endeavored to test the difference 

 in their fruits, but they all were of the same fine quality, with so 

 small a difference that it could scarcely be perceived. Two of the
