The general reader, after studying the foregoing data, may 

 conclude that in nearly all the valley districts of California there is 

 little difference in the length of the absolute frost-free period; also 

 that elevation influences temperature similarly in all parts of the 

 state. At elevations below 1500 feet, which is the point at which 

 foothills begin to shade into mountains, there are about two-thirds 

 of the whole year in which even the tenderest vegetation may be 

 considered practically safe from injury from frost, and particular 

 situations in which the frost-free period is even longer. On the 

 other hand, there are mountain valleys, with good soil and sunshine 

 and ample total heat for vegetables, in which tender plants must 

 be always protected, because frost may occur every month in the 

 year.
