depth of shade varies with the species. Some kinds fade as 

 pale as a tulip tree ; others have frequently the deep scarlet 

 hue, which often gives such a richness to the orange of the 

 sugar maple. 



That they have not hitherto received any attention from 

 the landscape gardener, in his efforts to improve country resi- 

 dences, is probably not because he has been insensible to the 

 beauties they are capable of enabling him to effect in his op- 

 erations, as on account of their never being found in a nurse- 

 ryman's collection ; from whence it is almost indispensable 

 for him to procure his materials. And why are they not kept 

 on hand by the nurseryman ? Simply because he is unaware 

 that the landscape gardener requires them. It is not the busi- 

 ness of a nurseryman to point out beauties ; his duty is to 

 supply the demand and wants of his customers, for whom he 

 would as soon keep on hand a supply of hickories as of any 

 other tree. 



There are two other circumstances which may in some de- 

 gree operate against the cultivation of hickories ; they are not 

 as easily transplanted, nor in many cases do they grow so fast 

 as some other trees. A hickory, transplanted directly from the 

 woods, will very rarely succeed, and it requires a warm sun 

 and dry atmosphere to make a good summer's growth. In a 

 cool, humid climate, such as Eugland, for instance, with even 

 the most careful culture, they can scarcely be made to grow ; 

 but there are few places in the States, where, with about the 

 same attention as is bestowed on the magnolia, they may not 

 be made to grow as fast, and thrive as well. 



The hickorys (Carya) were classed originally with the 

 walnuts (JuGLANs). They were separated by Rafinesque 

 under the name of Hickories, and subsequently by Nuttall 

 under the name above given and usually adopted. The prin- 

 cipal distinction resides in the fruit : the walnut having its 

 nut enclosed in a somewhat fleshy covering, without any 

 opening valves, and the nut itself being woody, rough and ir- 

 regularly furroAved ; while the hickory has its covering some- 

 what leathery, more or less opening by valves, and its nut bony 

 and smooth.
