scams, which, at complete maturity, open throughout their whole length for 

 the escape of the nut. The shell is thick, and of a yellowish hue ; while that 

 of the C. alba is white. The wood is of the same quality as that of C. alba : 

 it is brought to market in Philadelphia, but only in very small quantities. 

 The Gloucester hickory, Michaux considers to be a variety of this species ; 

 and he also mentions another, growing in the gardens of the Petit Trianon, 

 and to which he thinks the specific name of ambigua might be given ; as he is 

 doubtful whether it is a variety or a species. In the Horticultural Society's 

 Garden, and in the collection at Messrs. Loddiges's, and at White Knights, 

 there are plants marked Carya sulcata, or Jiiglans lacinidsa, which are dis- 

 tinguishable from all the other species of Carya, by their very large leaf- 

 lets, which, in autumn, die off sooner than those of any of the other sorts. 

 Nuts of this species are, in London, Is. 6d. a quart.
