proposed. If this is the correct solution we ought to expect the 

 upper south portions of the tree, owing largely to its exposure 

 to the ^varmth of the sun, to give the flattest apples, and the 

 lower north to give the most elongated ones, with the other two 

 portions intermediate. The calculations for the three years 

 1!)()8-10 are shown in Table 4.
