OAK FAMILY 



eleven to thirteen pairs of primary veins. The foliage mass 

 is a light yellow green, the tree in the open becomes round- 

 topped. The acorns are large, long-oval, usually in pairs and 

 borne in deep cups which are rough outside and very downy 

 within. They are endowed with the power of quick germina- 

 tion and scarcely reach the ground before the shell breaks 

 and the radicle protrudes. The kernel is sweetish and eager- 

 ly eaten by the squirrels. The fruit is never abundant.
