OVERYSSEL, one of the Seven United Provinces;
bounded on the east by the bishopric of Munster, on
the north by Friesland and the territory of Gronin-
gen, on the west by the river Yssel, and on the south
by the county of Zutphen and the bishopric of Mun-
ster. It is divided into three distinct parts; which are,
the territories of Drense, Twente, and Salland. There
are many morasses in this province, and but few inha-
bitants, in comparison of the rest. Its greatest riches
consist in turfs; which are dug up here, and sent to
the neighbouring provinces, particularly Holland.
