I went toward Bois-le-Duc, where we arrived on the 16th, at the time when the new citadel was advancing, with innumerable hands, and incomparable inventions for draining off the waters out of the fens and morasses about it, being by buckets, mills, cochleas ((The spiral water-screw of Archimedes. –AD)), pumps, and the like; in which the Hollanders are the most expert in Europe. Here were now sixteen companies and nine troops of horse. They were also cutting a new river, to pass from the town to a castle not far from it. Here we split our skiff, falling foul upon another through negligence of the master, who was fain to run aground, to our no little hazard. At our arrival, a soldier conveyed us to the Governor, where our names were taken, and our persons examined very strictly.
