Willow
The name willow applies to a wide variety
of shrubs and trees. There are more
than 300 species, or types, of willow.
One of the most familiar is the weeping
willow. This large tree has drooping
branches and twigs. The pussy willow is
another member of the willow family. It
is a bush that has silvery white, furry
buds on its branches in the spring.
Willows grow in North and South
America, Europe, and Asia in generally
cool areas. Most grow near rivers, lakes,
or swamps.Willow trees have tough,
deep roots. They help to keep the soil of
the coastline from washing away.

Willows vary greatly in size and shape.
They may be low shrubs that grow just
a few inches above the soil. Some are
large trees that reach more than 100
feet (30 meters) in height. The bark
may be gray, brown, or nearly black.
The leaves are narrow and green. On
some trees the twigs are bright yellow,
orange, or red.
Willow wood is used to make products
such as tool handles, baseball bats, and
furniture. A substance in some willow
bark is also used to make pain medicine.

In 1910Wilson was elected governor of
New Jersey. In 1912 the Democratic
Party chose him to run for president.
Wilson faced two opponents in the election:
PresidentWilliam Howard Taft
and former president Theodore
Roosevelt.Wilson won the election.
Presidency
Wilson successfully pushed Congress to
pass a number of laws. One law introduced
an income tax. Another law created
the Federal Reserve System, a
powerful economic agency. Other laws
regulated business and stopped child
labor.
In foreign affairs, revolution in Mexico
caused problems forWilson. In 1916
the Mexican rebel Pancho Villa crossed
the border and killed about 17 people in
New Mexico.Wilson sent U.S. forces
into Mexico, but they failed to catch
Villa.
WorldWar I
In 1914WorldWar I began in Europe.
Wilson kept the United States neutral,
meaning it did not take sides. After winning
reelection in 1916,Wilson tried to
end the war through peace talks. In early
1917, however, German submarines
began attacking neutral ships. In April
Wilson asked Congress to declare war.
In May 1917 Congress passed the Selective
Service Act, which gave the government
the right to order U.S. citizens to
join the military. The 2 million U.S.
soldiers sent to France helped defeat the
Germans. The war ended on November
11, 1918.
Making Peace
Wilson attended the peace conference in
Paris, France, after the war. He hoped to
include his Fourteen Points, or 14 ideas
for peace, in the agreement. The Treaty
of Versailles, signed in 1919, left out
many ofWilson’s ideas. However, it
