years' growth. I found in a row of 127 trees one where the Tetof- 

 ski was alive ; 126 were dead after having made a growth of from 

 six to ten feet. [ then examined a row of large yellow crab, top- 

 worked with Tetofski, and found two alive in a row of 74, the Te- 

 tofski having made about the same growth before being killed as 

 those on Transcendent. I examined also a row of Tetofski grafted 

 on common apple stocks, which had made a growth of from twelve 

 to fifteen fieet, and found in a row of 57 every tree alive. So that 

 I think if a tree dies worked either upon the top or root of a crab, 

 it is no sign of tenderness." 



Mr. Wilcox, of La Crosse, who has probably had more experi- 

 ence in root and top grafting upon the crab than any other person 

 in this country, reports both the Duchess and Tetofski a failure on 

 this plan, while other sorts of the apple are a perfect success, so 

 grafted, after ten years' trial. 



There must be found a congeniality of stock and scion inherent 

 in the race and nature of the two varieties to be united by graft- 

 ing. Experience will settle this matter by actual trial, but possi- 

 bly the microscope in its revelations of cell structure may open a 

 shorter road to the knowledge of it. 



In the winter of 1882 the writer exhibited at the annual meeting 

 of the Wisconsin Horticultural Society a section cut from a weep- 

 ing poplar grafted on cotton wood. The stock had died in the first 

 shock of winter, while the graft, some six or eight feet, was still 

 alive and vigorous. 



The members present were asked to explain it. Mr. Peffer ac- 

 counted for it by saying it Avas owing to the difference in cell 

 structure between the poplar and the cottonwood. The thin sap 

 in the growing season rose through the point of union, but when 

 elaborated and thickened above and attempting to return it was 

 obstructed at the graft and could not pass down to feed the trunk, 

 which had grown weak from lack of food and had died at last of 

 starvation. In the spring when nature called for new growth by 

 the ascension of the sap again in the thin state from the roots, then 

 the graft, receiving no supply from the dead trunk would have 

 died also. 



But little has been added at the recent annual meeting, to the 

 society's knowledge of top-working, and the subject seems to be 

 imperfectly understood. That we can grow many good sorts of 

 apples, and perhaps pears, by top-working, that we cannot suc- 

 ceed with any other way, is probably no less true here than in 

 other states. Probably we can grow tenderer sorts here in that
