Now, the difference In temperature between
these places, for the first 90 days in June, il
not greater, perhaps, than the difference fol-
any other 20 days in the entire year.
Again, il we turn our attention to the com.
paratiye temperature of the north side Of ouI
valley, and the neighboring Swamp ridge, we
will find like difference, although, unfortu-
nately, here we ha3e DO trustworthy observa.
tions made at the foot Of the HILL to whose
records we may refer. But frequently, as
have been ascending and descending this hill,
for this purpose, have observed fall Of from
90 to GO in the ascent, and corresponding
rise on the descent. Besides, at Cherryville,
whose altitude is 775 f., when the thermofne-
ter was at its lowest point at Lambertville,
the Indication of the mercury, as reported by
the Rev. Charles E. Young, was only 50 below
zero.
Well, what OF an t1ffs difference in tempera-
ture, depending on altitude? Why, very
much, as we may readily see II we look around
us a little. In those places whose altitude
above the level of the sea is least, the mercu-
ry is subjected to the greatest extremes OF
heat, and cold. In the Summer it is here the
hottest, in the Winter the coolest while up
ON the hills there is more uniformity Of tenn
perature. And now how does this act upon
vegetationp
Every plant requires Certain temperature
In order that it may mature The lemon does
not thrive in our groves, nor does our plum
do we'll within the tropics. The Gulf States
cultivate cotton, but il does not mature here
for want Of greater length of Summer, and
a high degree of heat. Our latitude produces
fax, but the heat of the Southern States IL
too great for its prosperity. The pea is sown
broadcast in the fields Of Canada, and North.
ern New York, but here 1t il a delicate gar
den plant, that fears the scorching rays of our
Summer sun.
Again, plants will vegetate through several
degrees Of latitude but they attain perfec-
tion only in a certain portion of the zone,
which portion is commonly at the middle Of
its extreme limits. For instance, our Com
mon Indian corn, OF iiaiye, vegetates from
the sOth to the 50th parallel, and even beyond
these limits, but it attains its maximum Of
development between $50 and APO. North Of
this limit It dwarfs, and as we recede farther
and farther towards the North, it grows less
and less in stature, until at last it is a plant
scarcely more than two feet high, and ripens
within fifty days from the time it is planted,
and the ripened grains are so hard that they
cannot be masticated by horses, unless at first
it undergoes the process Of maceration. But
south of this zone of maximum Development,
the stalks grow taller, a less number occupy a
given area, greater length Of time Is requir.
ed for its maturing, and when ripe, its grains
are soft and floury land it does not need te
be subjected to the macerating process fol
any kind Of domestic animals.
The maize, OF the maximum Of develop
rhent, contains certain percentage Of starch
gluten, sugar and oil. AS We pass from thii
central belt, or zone Of perfection Of the corn
the percentage Of the gluten, sugar and oil in
creases, until upon the Northern limit the,
attain their maximum Of quantity. But al
