SUMMARY FOR TWO YEARS. 



Under ordinary circumstances the last of the three years would have been chosen as a standard, 

 but the amount of fruit on the trees was so small, compared with that which fell long before it matured, 

 that it was out of the question. So I have taken the average of the last two years, both as to the 

 amount of Pit and yield. 



The highest amount of Pit was in plot 1, where a complete fertilizer was used. The lowest 

 was in plot 7, in which potash was left out of the complete fertilizer.
