so named from its situation beyond the river Yssel, one of the Seven United Provinces; bounded on the east by the bishopric of Munster, on the north by Friesland and the territory of Groningen, on the west by the river Yssel, and on the south by the county of Zutphen and the bishopric of Munster. It is divided into three distinct parts; which are the territories of Drenthe, Twente, and Salland. There are many morasses in this province, and but few inhabitants, in comparison of the rest. Its greatest riches consist in turfs; which are dug up here, and sent to the neighbouring provinces, particularly Holland. It extends near 60 miles in length from north to south, and 40 in breadth from east to west. The whole country is low and marshy, but it produces a tolerable quantity of corn. It was formerly a dependence of the bishopric of Utrecht, before Henry of Bavaria, bishop of that see, transferred the sovereignty of it to the emperor Charles V.
