It is entirely possible that other factors enter in, but a care- 

 ful consideration of latitude, altitude, amount and intensity of 

 sunlight, rainfall and other considerations fail to show anything 

 that can be demonstrated as having any constant effect. To 

 determine just what the cause is will require much patient 

 investigation. 



Size. 

 The size of the apples appears to be largely governed in any 

 locality by the summer temperature. This is shown by the 

 larger apples in the warmer season of 1908. In only two cases 

 has a higher temperature failed to produce larger apples, and in 

 one case the apples are larger while the temperature remains 

 the same. The other eight comparisons in Table 4 show a 

 higher temperature and larger apples. It may also be noted that 

 a comparatively low temperature in the north produces as large 

 or larger apples than a much higher temperature farther south. 

 It is of course to be understood that methods of cultivation have 

 an effect on size sometimes greater than temperature, and this 

 fact, together with some possible selection on the part of the 

 shipper, probably accounts for the above exception to the gen- 

 eral rule. 



Flesh. 



During the winter of 1007 careful notes were kept on the 

 quality of the apples from the different localities. In the judg- 

 ment of the writer the various lots would rank in quality about 

 in the following order with a notable difference between 9 and
