SLOPES FROM THE WORLD RIDGE.

Up we go! Now we can look far out over the
lowlands. The air is cooler. See the great trees
with moss growing on their trunks and branches.

At length we reach grassy places and: clover
patches, on the mountain sides. Now we have passed
the clover, and find only bushes and bare rocks.

-Here is the edge of a great snowcap. We can

climb no farther, and yet the top of the peak is far
above us. This peak is very high, but many of the
peaks in the highland of Tibet are
much higher.

42. Slopes from the
World Ridge.

Each of the four great high-
lands sends out a long slope
on one side, and a short slope
on the other side. The long
slépes are inside the world
ridge. In most places they
make wide plains before reach-
ing the level of the sea.

The slopes outside the world ridge are
shorter than those inside. In most places the
short slopes form only a narrow lowland
along the shores.

Natives of the Selvas.

43. Selvas.

Vast forests, called selvas, cover a large part
of the slope east of the Andes highland. Long
rivers wind through these forests and often
overflow the land.

Find the word selvas on the map on page 25.

Many tribes of Indians live along the borders
of the streams. They ;

44. Western Plains.

Where is the Rocky Mountain highland?
What have you read about this part of the
world ridge? On which side
of the Rocky mountains is
the long slope?

A very large part of this
slope consists of wide plains.
In some places they are barren,
but im other places they are
covered with grain and cotton.

Just east of the Rocky
mountains the grassy slopes
feed large herds of cattle.
These grazing plains stretch
away for hundreds of miles.
Perhaps some of the meat
which you have eaten came
from these plains.

45. Tundras.

Find the word tundras on the map. The
tundras are marshy and mossy plains that
form a part of the long slope far to the north
of Tibet. They lie along the shore of a very
cold sea. In most places the soil of the
In sum-
mer it thaws slightly at the surface.

Herds of reindeer feed on a small gray plant,
called reindeer moss, that grows on the tun-
dras. On page 81 there is a picture of these
dreary plains. South of the tundras there
are large forests and grassy slopes.
