OS DECIMAL Coinage. BY j. II. ALEXANDER.
This communication introduced pamphlet which
we did not SEE. From the drift Of the communication
we gathered that Mr. Ae1as der would advice US 20
reduce our hsfeagle 10 the value of the pound ste
ing, if lot indeed to make that the unit Of our
system. He thinks the change heproposes not greater
than has been made more than once in our coinage
AFTERNOON SESSION
The Association appointed Committee TO memo.
riaize the State Of New-York to make an experiment
in fsh-breeding.
The following gentlemen were appointed the Local
Committee for the next meeting at Albany:
T.Romeyn Best, ErsEu. Coming Gidson nswiey Thomas
w Ocou d. D. Barnard the Hon. A. Parker, Ezra Prem
tiee J. V. L. Pruyn Dr.. 1bom.
Mr.. BRAIsTRD said his parting word and bade the
Association adieu. He referred to Calico and says
that be shs1 come back when they have recognized

IL The SECTION OF GEOLOGY
Prof GUYoT spoke ON the coDfguration ofthesoil in
New-England. He said that our one great want was
reliable maps. Except those Of the Coast Survey we
have no reliable maps. But there features Of
country that no ordinary maps can give. New-En
gland is part of masC Of land cut off from the rest
of North America by the low valleys of the Hudson
and Lake ChamplaiD, and the River and Gulf of St.
Lawre1ce. The highest point in this demarkatOn is
the south of Lake Champlsn, where it is only l4o
f. et high. The mountains continuation OF the
Appalachian cOan A section west from Boston rises
gradually with an undulane character and elongated
hills TO Worcester Beyond Worcester is terrace
about 0C0 feet high and 40 miles wide-a broad, un
dulang plateau that extends down to the State of
Connecticut. The low lands have the Blue Hills near
BOetoD, ard in the plateau more hills OF some
1900 feet, and some higher peaks of 900 feet We
cone TO the Connecticut and go down nearly TO
the level at Springfield, only 40 feet above Here
are trap.rocks OF some 1900 feet high. On west we
have 20 miles high of rolling plateau. Then we come
TO greater elevations. The railroad passes at AS.
PassIg still higher peaks to the elevated val
ley Of PtsfeO, with pesks of 3, 500 feet, and after
that descend 10 tide water. Thus the Connecticut
River divides plateau. The rise is TO the west and
tlif iise excnds TO plateau Of 800 to 200 feet,
where rises the Susquehannah. Further north the
country rises and the Connecticut River in Vermont
is 500 feet high. Still further north ia an immense and
very high Ilaeau and here the Laracer of The swes
below is broken up but still ,raceabe. This the
great valley Of the st. Johns, where the streams
run parallel TO the coast TIL they find chance to
break over the edge. SO there are two great chains
that continue from the Sound ~ the Bay of Chaleurs.
These chains have bend at the White Mountains
and there ia the change of character and the peaks
though OF so hieh a. the White Mountains, 800 are
sill quite high COO feet and Mount Kaahdn s said TO
rice 10 even COO. The Eastern mountains peaks
on O swtlled base-the west are continuous chain.
They are upheavals o. a different age. The White
MountsDs are high peaks on high swell but not on
the highest SWELL which is still further Iorth. The
White Mountains are not in accordance with the
ChaD. There are two systems crossing each other,
ano Mount WashiI gOn IS at the inteTs cton of the
two. We may find three or four upheavGls in the
whole tract east of the Hudson, but common law
seems TO pervade them all.
Prof HALL said that what was called the granite
Of tie Green Mountains was but beds of the Lowes
suran group and that the eastern ridge consisted of
TIE Niagara group and limestone identical with the
Hilderberg. Tie continuation of the western range
toward Gaspe belonged to the Upper Silurau and
inuson of the eastern range to the Bae des Chaleurs
consisted of bODierous strata. The carbonierous
roc il New Bunwick were 5000 feet thick, and 1t
was well known that causes connected with the thick
est strata produced The highest mountains

Mr. Daniels and Mr Whitney.
