 and there, relieved of competition, shows what it can do in the 

 way of producing large and regular crops. But the nuts are 

 wHd. There has been but little selection for improved varie- 

 ties and little scientific culture of nut-bearing trees. When 

 we consider the abundance and value of their product, the 

 permanence of their occupation of the ground, the slight cost 

 in labor of their maintenance, and the conservation of the soil 

 which they promote, this neglect of nut crops among us seems 

 unfortunate. 



Two families of plants furnish most of our 



valuable nuts: the hickory family and the 



oak famjily. The former includes the more 



valuable kinds of nuts; besides true hickories, 



these are pecans, butter-nuts and walnuts. 



In all these there is a bony shell, enclosing 



the four-lobed and wrinkled edible seed. 



The oak fanuly includes besides the acorns 



(few of which are valuable as human food) 



the chestnuts, the filberts, the hazels and the 



beech nuts. In these there is a homy shell
