But it viii be with reference to the question Of fer
sliEers that the report of Dr. Cock will be consulted
most eagerly by those interested in agriculture.
More than 100 pages of the volume are devoted to
the subject Of marls, and any one who knows the
prominent part which mari has played in the aercul-
tnre Of NewJersey viii pronounce them well be-
stewed. This wonderful natural fertilizer is found
IN belt running diagOnally across the State from
Raritan Bay to the Delaware River interseCting the
counties of Monmouth, Burlington, Camden, and
Gloucester. 1t is dug in vast quantities to be dis
kributed on the neighbOring lands and is shipped
by railroad aud canal to all parts Of the State and
adjoining States. 1t has raised the fertility
of Monmouth and Burlington Counties to
an unexamped pitch, and is fast reclaiming
fhe unproductve lands and literally making the
wilderness and solitary place TO rejoice and blossom
rs the rose. II Eew-Jersoy had been endowed with
mines of gold and silver it would have been poor
boon compared with the possession Of their rich and
hexhaustible beds of mari. The value to the public
Of an intelligent and comprehensive account of the
nature qualities, uses and localities Of useful
material cannot be Oyerated 1t removes it from the
.egien of doubt and uncertainty to of positive
knowledge 1t enables the farmer to know exactly
where to look for this valuable fertilizer, how he
may obtain 1t, and how he may prOhtably employ it
Ia the cultivation of his lands
g. Mineral ResouroeS-It will surprise not few TO
learn from this report that NewJersey is one Of the
great mineral States Of the Union. About one
eighth of all the iron Of the country is taken from
It's mines and the State stands fifth in the amount Of
iron made" The iron mines Of New-Jersey are To-
Gated in the northern part, and fully described
and their quality and extent indicated in the pages
of the report. Among the most valuable of the
beautiful series of maps with which this report is
accompanied are those of these interesting iron
gions. But iron is not the only metal which the
6ttle State furnishes. More than one-half of all
she zinc products in the Union mined and manu-
,actured in New-Jerseyp Copper is also found
widely distributed but not in rich deposits and with
oew exceptions, has not as yet been proftably
worked.
Although it may not be a strictly scientific order.
we will classify under mineral resources the ether
valuable products drawn from the soil of Jersey
Chief among these sources of wealth and profit
are her vast clay-beds. They are found along the
shores Of the Raritan River and Bay and at various
points in the valleys of tho Passaie Hackensack, and
Delaware Rivers. They consist Of all qualities and
varieties from that which employed in the manu-
faeture Of common brick to that which is employed
IN manufacturing the finest pottery wares More
than 100000 of common brick are manufactured
annually. The pottoIes at Trenten are the most
extensive IN this country, and large part of their
material is drawn from Ncw-Jersey soil Fire-brck

provided for. Indeed we can suggest in her supplies

her generous DeighbOr Pennsylvania supplies her so
abundantly and cheaply that it is hardly felt as
want. She has plenty Of peat, however, so that
when she is put to it she even supply her own
fuel.
