SUMMER MEETING. 99 



to the snow. Marianna plum, on an exposed slope, very vigorous, endured the 

 cold remarkably well. The beach-plum of the sea-cost (Primus maritima) 

 was not injured, nor was the sand-cherry (Primus pumila). The Eussian apri- 

 cot (Primus siberica) behaved singularly. Out of forty good seedlings, from 

 two to three feet high, sixteen were badly injured, and as many more were 

 killed outright, while out of twenty-five larger ones on peach roots, and very 

 vigorous, standiDg alongside the others, and set at the same time, but two were 

 injured, and none killed. I do not understand it. Double-flowering sweet 

 cherry, in an exposed place, w&s not injured. 



Three good bushes of Meech's Prolific quince were killed to the snow. 

 Soil warm and well drained. 



Young shoots of white and black mulberries (Morns alba and M. nigra) 

 were killed. Russian mulberry uninjured. 



Reeder raspberries, on well-drained soil, and which had been injured by the 

 winter of '84-5, were killed root and branch. Turners, which stood by them 

 during the two winters, were not injured. Cuthbert, Shaffer, Gregg, were not 

 injured. Blackberries came through in good condition. 



Young shoots of the Japanese pear Mikado, were injured, as were those of 

 Madam Von Siebold. The Diamyo endured the cold without injury. Same with 

 the Keiffer. Leconte and Comet were killed to the ground. The silver-leafed 

 pear was not injured. These pears were all set in the spring of 1885, on rich 

 but well-drained loam. 



The ornamental European Mountain ash-like trees, Pyrus hybrida and P. 

 domestica, were not injured. By the way, we bought P. hybrida of Parsons 

 under the name of Pyrus (or sorbus) sambucifolia. The real Pyrus sambuci- 

 folia, which is a native of this country, we have never yet seen among market 

 trees. The double-flowering apple did not receive injury. 



Deutzia crewafo was considerably injured. Japanese maples (Acer polymor- 

 phum), in warm soil, were killed to snow-line. 



River's purple beech, the black English oak (Quercus robur forma nigri- 

 cans), and the weeping European beech, sustained no injury. 



The weeping European basswood was not injured. It is a fine tree. Ours 

 is young. 



Mr. A. Pettet was next introduced who spoke of 



SOME EXPERIMENTS IN GRAFTING. 



Very largely for the purpose of interesting the students and getting them 

 acquainted with methods, a series of experiments in various directions are car- 

 ried on each year, and from a small plat devoted to practices in grafting these 

 notes are taken: 



Primus pumila, the wild sand cherry, is doing well root-grafted upon peach ; 

 upon stocks of choke cherry (Primus Virginiana), the wild plum (P. Ameri- 

 cana) and common cherry scions did not start. 



Prunus pissardi, the new purple-leaved plum, is growing remarkably well 

 upon Prunus Americana stocks. The foliage is much darker upon these wild 

 plum stocks than upon common plum stocks. We have a number of trees of 

 this remarkable plum, and the foliage has maintained its rich purple during 

 an excessive drouth. Purple beech has faded. If this plum were hardy here 

 it would be a great acquisition. With us it has appeared to take better upon 

 the wild plum than upon the cultivated one.
