second year. We may then commence, leaving the lower limbs 

 long, and gradually shortening the branches as we approach 

 the top, so that the fence may gradually taper up in a wedge- 

 like form. If treated in this manner, the Logwood forms a 

 hedge superior to almost any other, not excepting even the 

 Hawthorn, which, in appearance, it so much resembles. I may 

 instance the Logwood fences in Vere, which are trimmed in 

 this manner, and are equal to any of the Hawthorn fences to he 

 seen in England. 



The Logwood is a powerful astringent, and may be employed 

 as a substitute for Kino, Catechu, or any other of this class of 

 remedies. In diarrhoea and chronic dysentery, the decoction is 

 used with great benefit. In Long's work, it is recommended 

 to take 2 oz. of the chips, and a quart each of milk and of water, 

 and to boil the whole down to one quart ; of which, a tea-cupful 

 is to be given every 3 hours. As an external application, on 

 one occasion the leaves, beat up into a pulp with a little tur- 

 pentine added, were 'applied to a phagedenic sore, of a very 

 obstinate character, with the best effects.
