same plot. These trees are not, however, included in the list which were 

 permanently discarded because of poor health, low vitality or injury from wind 

 or winter killing. They are normal trees in appearance, and considered in- 

 dividually, may, from time to time, throw light of equal significance on the 

 subject of fruit bud formation, with other trees in the same plot. These trees, 

 whose results are not included in the averages, appear to be in every way simi- 

 lar to their neighbors, and their low production is not traceable to any apparent 

 cause or difference in treatment. The fairness of this elimination of exceptional 

 individuals becomes apparent on a comparison of charts 2 and 3. Chart 

 No. 2 shows in a graphic form the distribution of apples, tree by tree for the 

 entire orchard. Chart No. 3 shows the distribution in the various plots when 

 the exceptional individuals and discarded trees have been omitted. 



With the exception of plot No. 3, comment is unnecessary in the presentation 

 of the tables showing the productions of the plots. Plot No. 3 shows one of 

 the largest average yields per tree in the entire orchard. It must be taken into 

 account, however, that this plot contains only 5 trees, all other plots containing 

 from two to four times this number of individuals. A reference to chart No. 1 

 (the plan of the orchard) will show that these 5 individuals have more soil area 

 per tree and more light and air than the trees in other plots. This is due to 

 the death of the surrounding trees at some time previous to the lease of the 

 orchard by the college. Some allowance must therefore be made when com- 

 paring this plot with other plots.
