the inhabitants having come in and settled within the last six 
years. The centre and northern part of the county is still 
spaisely populated;. but as the lands are cheap and of an excel¬ 
lent quality, we have every reason to believe that our county 
will soon have a population equal to the older settled counties 
of the State. 
INDUSTRY OF WALWORTH COUNTY. 
BY DAVID WILLIAMS, OF SPRINGFIELD. 
Topography. —The County of Walworth consists of open¬ 
ings, prairies, marshes and lakes—about one-fourth prairie, 
one-tenth lake and marsh, the remainder openings and groves. 
The surface of the county is gently undulating, broken on the 
north-west and south-east into knobs or sharp conical hills, 
composed mainly of pebbles of limestone. These knobs are 
nearly all wooded with scrub oak, some affording good timber. 
The county is well watered, has numerous springs and five 
mill streams, with numerous branches, affording abundance of 
water power. There are also twenty-five lakes of various 
sizes. Geneva lake, the largest, has a length of about eight 
miles, and maximum width of about two miles. 
The central portion of the county, presents an elevated 
nearly level plain, dividing the county into two geographically 
equal parts ; that on the west is drained into Rock river, and 
the eastern half into Fox river. 
Sylva. —Nearly two-thirds of the county was originally 
covered with a forest of oak, usually called “ timbered open¬ 
ings/’ and composed mainly of white, yellow, burr, black and 
pin oaks, with a few shell-bark hickories. The shores of some 
of the lakes, also some creek bottoms, were covered with a 
heavy growth of timber of various kinds—oaks of many vari¬ 
eties, black walnut, butternut, sugar maple, linden and two or 
three varieties of elm. These are all quite too rapidly disap¬ 
pearing. As substitutes for wood fuel, we have peat in great 
abundance, and quite general distribution.
