These people are most excellent mathematicians, and arrived to a great perfection in mechanics, by the countenance and encouragement of the emperor, who is a renowned patron of learning. This prince has several machines fixed on wheels, for the carriage of trees and other great weights. He often builds his largest men of war, whereof some are nine feet long, in the woods where the timber grows, and has them carried on these engines three or four hundred yards to the sea.

Five hundred carpenters and engineers were immediately set at work to prepare the greatest engine they had. It was a frame of wood raised three inches from the ground, about seven feet long, and four wide, moving upon twenty-two wheels. The shout I heard was upon the arrival of this engine, which, it seems, set out in four hours after my landing. It was brought parallel to me, as I lay.
