314 Report of the Horticultural Department of the 



tioned. . This is well illustrated in the following- account of the 

 individual records of yields of six Greening trees for a period of 

 ten years. Three of these six trees received annual applications 

 of wood ashes, while the other three did not. In all other 

 respects they were all similarly treated. The trees are all of the 

 same age and are located in one of the Station orchards. They 

 were planted in 1850. These trees all bore a full crop in 1896, 

 in which year they showed considerable differences in yield. It 

 is a remarkable fact that they retained practically the same rela- 

 tive rank in productiveness throughout the period of ten years 

 which they showed in 1896.

In 1898 tree 6 lost about 8 per ct. of its bearing wood. Its 

 record from 1898 to 1902 should be correspondingly raised to 

 make it comparable with the other trees for those years. The 

 corrected statements appear in parentheses. Using the figures 

 showing the actual yields, the percentages in the following table 

 are obtained. The first column shows for 1896 the percentage 

 which the yield of each tree formed of the total yield of the six 

 trees. The second column in a similar way shows for the ten- 

 year period the percentage which the yield of each tree formed 

 of the total yield of the six trees.
