Variations in the Size of the Fruit. — The behaviour of dwarf 

 and standard apple trees during the first ten years since they 

 were planted has been examined by measuring the size of the 

 leaves, the size of the trees, the weight of the crops, and the 

 average size of the fruits. It would appear that the average 

 size of the leaf of the tree diminishes more or less regularly 

 throughout this period, and the average size of the fruit 

 probably does the same, but it shows greater irregularities 

 than that of the leaves, being much more affected by the 

 character of the season. When a tree is allowed to overbear, 

 or when the number of fruits in each truss is excessive, the size 

 of the fruit will suffer ; but, except in these extreme cases, it
