Fruit-growing can never be reduced to a dead level 
of ideals and practice. In one place great speciali- 
zation may be most profitable, but in another place

purpose varieties—may be best. 
Location with reference to frosts.—In the last 
chapter, the general influence of cold and heat in 
determining the fruit zones was discussed. At that 
place, the subject was the average annual tempera- 
ture. But within these various zones there are end- 
less minor variations in physiographical features which 
have a direct influence in determining the areas of
