A comparison of the records of the trees listed in ranks 45, 51. and 
54 of Tables I and II will bring out further the variations in production 
that may occur witliin a strain as that term is here employed. These 
three trees produced practically the same average yields for the 
4-year period, but their crops for each year have varied considerably 
and in very different ratios . 
The tree listed in rank 45 is representative of a small class which 
shows a gradual decrease in production each year. This is. of course, 
an undesirable condition, and in commercial practice such trees should 
be top-worked as soon as their production falls below the point of 
profitableness. The tree listed in rank 51 is representative of the 
most desirable group of any commercially valuable strain, namely, 
that one in which the crop production is gradually increased from year 
to year. The trees recorded in ranks 2. 5, 9, 16, 17, 21, 27, and 37
