Of the world. With these charts spseac
out before him, he will explain how ,hes,

rences of climate there are soonest reached
not by travelling north or south as with
US, but by travelling eas, or west.
He will perceive that the winds which
circulate over America, are for the mos,
part fresh from the ocean, while those
which cross Africa come mostly over the
laud from Asia. upon whose high noun
tain tops they have precipha,ed all their
moisture. Hence he will tell you, iha,
Africa for the most part is dry county {;
America, in comparison, wet one. And
in proof oflhis. he will point you to the
arid plains there, and to our grea, rivers
here, as the Amazon and the Mississippi,
maintaining that the quantity Of water an.
nuaIly discharged by them, is but another
expression for the difference bet cen the
amount Of rain which falls in, and the
amount which is taken up from, the valleys
that are drained by these rivers. The
charts teach him to regard rivers, in one
respect al least, as great rain gauges sci
up by nature for her own manifold pur-
poses.
He will show you how the waters lha,
run down the Amazon river and its tribu.
'aries, are taken up by the winds of heav.
en- from the Atlantic Ocean, and carried
in invisible streams through the air, to the
sources Of these rivers in the upper coun-

rom the reasoning Of the charts. that the
waters which run down the Mississpp
liver are evaporated from the Pacific
Ocean, and brought by the clouds and the
winds across the mountains, TO fertitze |
md frucsify that teeming valley.
And then, with hymn in his heart, he
will sing you in silence his song OF praise /;
