 same character with the seed-nut. Its dimensions, at this 

 period, were as follows : Feet, inches.

 Circumference at giving off the branches - 1 4f 

 The boughs are firm, and no where drawn out or weakly :

The bark of the tree is uniformly smooth, and of a deep 

 brownish green colour ; and it has none of the silvery white- 

 ness which appears upon the skins of some healthy young 

 Walnut-trees. 



I am not sufficiently experienced in horticulture to know 

 whether the habit of this tree is out of the ordinary course 

 of growth and bearing ; but if it should prove to be so, the 

 narrative of its planting may help to show the favourable 

 situations for that useful species of tree. 



Allow me to suggest, that the composition and the pre-

 and that it might be of great practical utility to detennine
