REPORT OF THE HORTICULTURIST. 113 



" When the snow disappeared in spring it was found that nearly all these 

 autumn planted trees were more or less injured, many of them killed to the snow 

 line. The fact that such varieties as Duchess of Oldenburg, Tetofsky andFameuse, 

 — of which there are healthy bearing trees growing unharmed within a short distance 

 of the farm — suffered equally with the tender sorts, showed clearly that these failures 

 were due to the unfavourable season for planting, rather than the lack of hardiness of 

 some of the sorts tested." 



In this instance it is reasonable to suppose that the injury would not have been 

 so severe but for the unusually cold weather of the previous winter ; it is right to con- 

 clude, however, that fall planting of fruit trees cannot be safely practised in this 

 locality and in other places with similar climatic conditions. 



With the object in securing data on the same subject, with regard to forest 

 trees, the following experiment was carried out. Thirty trees each of Green Ash 

 (Fraxinus viridis), Black Walnut (Juglans nigra), Eed OaS (Quercus rubra) and 

 European Mountain Ash {Pyrus aucuparia), were selected in the autumn of 1892. 

 These had for three years been in nursery rows under good cultivation and were 

 thrifty trees eight to ten feet high. Each variety was separated into three lots of 

 ten trees each; the first assortment being planted without pruning; the second 

 having three-quarters of the last season's growth removed, while the tops of the trees 

 in the third lot were cut back to the main stems. They were then carefully set in 

 rows four feet apart, and three feet apart in the row. 



In the spring of 1893, on the appi-oach of the planting season, a duplicate col- 

 lection of the same varieties was made and treated in a manner similar to those 

 which had been set out the fall previous. 



The following tabular data gives the results in detail : —
