24 Mahoning Valley — Tertiary Deposits. 
and in this country, where the accumulation of property so generally 
absorbs the public mind, few such men are to be found. 
May 10th, being the Sabbath, was passed as a day of contempla-

Mahoning Valley, May 11.—Dr. K. and myself visited an inter- 
esting locality of fossil vegetable remains, called ‘‘ Mariner’s mills,” 
lying on a small creek discharging into the Mahoning, on the north 
side of the stream. In going out, we crossed the valley of the Ma- 
honing, up which the Ohio and Pennsylvania Canal will pass, in its 
progress westward to join the Ohio Canal, and unite the waters of 
Lake Erie with those of the Delaware. The Mahoning valley or 
alluvion is about a mile broad, and depressed nearly one hundred 
feet below the surface of the adjacent country. The scil is very 
fertile, and finely cultivated. The whole region is gently undula- 
ting, and beautifully formed for agricultural purposes, so that in a 
few years it will be improved like a garden. The present staple 
productions of Trumbull County, and generally of the “‘ Western 
Reserve,’”’ are those of the dairy, fat beeves and wheat. The soil 
and climate are both congenial to grazing, and cattle, as Jarge and 
fine as those from the prairies of the west, are raised here with little 
trouble. The dairy farms usually support from forty to one hun- 
dred cows, and with judicious management are profitable. Traders 
in produce generally contract with the farmers for their cheese be- 
fore it is made, stipulating a certain price, to be paid on delivery, 
generally from six to seven cents per pound, at the door of the dairy, 
or at some adjacent store. Butter, in quantity, and of the best qual- 
ity, is sold for eight or nine cents. There is scarcely a waste acre 
of land on “the Reserve ;” nearly all may be cultivated, although 
some of the low tracts will require draining. 
Tertiary Deposits.—The surface of the country, from the Penn- 
sylvania line, north of lat..41°, appears to be generally an imperfect 
tertiary formation, resting on the secondary, and is composed of argil- 
laceous earth and decayed vegetable matter. Granite and other primi- 
tive bowlders are scattered all over the earth, with pebbles and gravel 
intermixed to a considerable depth, varying from twenty to thirty or 
more feet. It is, strictly speaking, neither tertiary or diluvial, but 
partakes of the characters of both these formations. In the vicinity 
of Poland, this deposit rests on a bed of blue clay, plastic and tena- 
cious, like that slowly deposited from water when in a state of rest, 
varying in thickness from six to fifteen feet. The blue clay reposes
