at least no species of timber, is possessed of 

 both, these qualities together in so great a degree 

 as British Oak. Almost all arts and manufac- 

 tures are indebted to it ; but in ship-building, 

 and bearing burdens, its elasticity and strength 

 are applied to most advantage. I mention these 

 mechanic uses only because gome of its chief 

 beauties are connected with them. Thus it is not 

 the erect, stately tree that is always the most 

 useful in ship-building; but more often the 

 crooked one, forming short turns, and elbows, 

 which the shipwrights and carpenters commonly
