in the sandy regions are large aud almostlmpene-
trable swamps ofcedar, which ia used for the pur-
nose Of fencing. These swanps omstimes sell
Tor three hundred dollars acre.
From four to twenty feet below the surface OF
the soil throughout great portion OF the alnvial
district is found q species Of the greensh blue
earth mixed with shells, forming good quality
of mari This substance renders this section OF
country doubly valuable, in an agricultural point
ofview in consequence Of its being used as ma
nure TO reclaim the soil THE more sandy portions
Of the district. The essential property OF mari as
manure is lime, and its value is increased or di-
minished in proportion to the amount of calcare-
Gus matter it contains There are marls OF purer
nature than any which can be found nthe state
OF New Jersey the Jersey marls being known as
the she'll clay and stone marls. The shell mari
is composed of testacoCs matter in various
quantities and degrees ofcombination and 1t not
unfrequently happens that bones OF marine ana
land animals and shells are found imbedded III H.
such as the benes of the rhinoceros, elephants
teeth deers horns, bones Of the whale, sharks
teeth, end entire skeletons of fish, together with
graphites, belemnites cardites, and various shell
fish The clay mari derives its name from the
quantity ofclay in union with calcareous supstan-
ces This kind of mari varies in coor-oem8
blue brown and yellowish, and retain moisture
longer than others. In the stone mari sand IS
combined with calcareous and argilaceous matter
which gives hardness in proportion to its guam
tity but where it is OF a thin and llm1nar struc-
ture, it is known as slate mari. All these marls,
from the clay they contain, are sotened by water
and if exposed to the action Of the atmosphere,
soon crumble to powder
Some authors class the mari region of New
Jersey with the ferruginous sand formation OF the
United States So far as it has yet been lnyestl-
gated it may, perhaps, be located between two
lines one running from Trenton to Amboy or harl-
tan Bay, the other from Deal, on the Atlantic.
