The Beech which has little of Earthiness, Humidity and Fire, but great plenty of Air, is not very solid and easily breaks.
The Poplar and the Linden Trees are only good for light Work, they are easily cut and so finest for Carving.
The Alder is good to make Piles of in Marshy Places.
The Elm and the Ash have this property, that they do not easily cleave, and that they are pliable.
The Yoke-Elm is likewise pliable, and yet very strong; this is the Reason that they made Yokes for their Oxen of them in Old Time.
The Pine and the Cypress have this defect, that they easily bend under any Weight, because of their great Humidity; but they have this Advantage, that their Humidity does not engender Worms, because of their Bitterness which kills them.

There is a remarkable Story of this Wood, which is, That when Julius Cæsar besieg'd a Castle at the Foot of the Alpes, there was a Tower built of this Wood, which prov'd the Principal Defence of the Place. He thought to take it easily by making a great Fire at the Foot of the Tower, but for all this great Fire, the Tower did not suffer the least Damage.
