Thus, we find the climate of Maryland within the limits
of vine culture; the mean summer temperature being 73°.4;
for July, 76°; for August, 75°.5, and for September, 65°.5.

The same for the State of New York, summer mean 67°.5;
July, 72°.6; August 69°.2, and September, 59°.5. As to
the quantity of rain, it is about the same; and from the tem-
perature, the seasons of Maryland precede New York about
five weeks.

The above table, favorable as it is, does not do full justice
to the climate of the tide-water section of Maryland, as the
observations of Maryland were either made above or on its
extreme Northern and Western limits. Its mean average win-
ter temperature is several degrees higher, whilst its summer
temperature does not exceed that given in the above table.

From the contiguity of Baltimore and Washington to large
bodies of water flowing from ice and snow in the first months
of Spring, it will be understood how their climate do not fairly
represent that of tide-water Maryland. The cold weather is in-
tensified and protracted in both of these places by the large
bodies of fresh, cold water brought to the latter place by the
Potomac from the ice and snows of the mountains of Mary-
land and Virginia, and to the former by the waters of the Sus-
quehannah, flowing from their icy fountains in the mountains
of Pennsylvania and New York. The cold water from these
streams materially retards the advent of Spring. Summer
fruits and Spring flowers are from ten days to a fortnight
earlier at Annapolis and adjacent parts than in the neighbor-
hood of these cities, though not a half degree south of them.
As we go down the Bay and Potomac the difference is still
more manifest than between these two places and Annapolis.

HEALTH.

Without this, one of the greatest of all blessings no
place should be sought or recommended whatever induce-
ments it might otherwise offer as to the attainment of wealth,
and happily for us this is enjoyed in the State of Maryland
in an equal if not superior degree to that of any other sec-
tions of the Union; of by far the larger part of the State,
this is generally acknowledged and admitted, as I shall
presently show by reference to official documents^ of the high-
est authority, and of the hygenic conditions of the other parts
the proof is circumstantial, but no less conclusive, and I in-
voke the closest scrutiny to the facts which may be given and
conclusions which may be drawn, not only in this but in
every other particular of this Exposition:

In the eighth census of the United States for 1860, page 25,
is given the "natural divisions of the Union," and that
numbered III. (3) is called the Alleghany region, and this is
spoken of on the sucpeeding page "as a region of great salu-
brity" and it is also stated that this region is so constituted
