great beauty; indeed, if worked up for furniture, or used 
for any ornamental purposes whatever, we cannot fail to 
admire it. The figured logs, therefore, possess a consi¬ 
derably enhanced value over those of a plainer descrip¬ 
tion, and high, even fabulous prices are often realised for 
them. 
Cuba or Spanish Mahogany is durable, and is em¬ 
ployed for a variety of purposes. It has been very 
advantageously used in the building of ships of war in 
place of Oak for beams, planking, stanchions, &c. ; its 
strength and rigidity rendering it admirably fitted for 
these, while, being of rnoderate specific gravity, it was 
safe to use it either above, at, oj below the line of 
flotation ; but in civil architecture it is not much used, 
on account of the high price it obtains over other 
woods.
