not allow of the great differences of tempera-
tnre now found at short intervals. One might
suppose as he observes the wind moving along
over The surface Of the earth, that the whole
column of atmosphere above him passed over
hills and across valleys with the same rapidity.
but such is not the case. 1.-two instruments
so arranged as to test the velocity Of the
wind, are fixed the one ON the sourland Mt.
and the other in the Redshale valley. we soon
see that the air ON the hin Is passing much
more rapidly than that in the valley.
Again If an thermometer Is fixed ON the
Swamp ridge, another just at its southern
foot, and third about the centre Of the valley,
we win see that on the ridge the velocity is
greatest at the foot it is least, and that as we
pass toward and beyond the centre, it acceIc-
rates in speed until as we begin to near the
foot of the Sourland ridge we again ffuf the
breeze to grow more gentle.
This may be explained in this way. From
the surfce of the earth upwards the air is in
layers or strata. Each stratum or layer has
density peculiar to ITSELF and a rapidity
Of motion peculiar to itself. As law, the
stratum nearest the earth has the greatest
density the one next above. is next in
density, and SO on, till tho limits of
the atmosphere is reached. As to tempera-
ture, from the middle of the day till
till midnight, the layers decrease in amount
of heat from below upward but from mid
night till morning, this condition Of things is
reversed.
The qualification of the atmosphere Is easily
observed by passing down a steep hill into q
valley, at the close of the day. Almost every
one has had an opportunity to note the sud.

Sometimes the Change Is SO great, that in de-
cending only few feet, we feel tire need of
extra clothing and by the time we have de-
scenietf another 90 Or 100 feet, we merge into
stratum that rs quite as warm as the layers
near the top Of the hin. Again; We are
