Early Industry and Inventions
Study Guide
New England Factories
Why was
New England a good place to set up a
factory?
Answer
New England is a good place to
set up a factory because it has
many fast moving rivers, it has
good ships and access to the
ocean, and they have a willing
labor force.
Interchangeable Parts
How did interchangeable parts
change industry and
management?
Answer
How interchangeable parts changed industry and
management is before interchangeable parts,
manufacturing was slow and everything had to be
made one at a time. So when the U.S. government
hired Eli Whitney in 1797 to make 10,000 guns,
he sought a better way to make guns faster. He
demonstrated interchangeable parts by assembling
a musket in seconds using musket parts. Ever
since this, manufacturers used the same techniques
and sped up manufacturing and made the
industry more robust.
Telegraphs
How did the telegraph
revolutionize long distance
communication?
Answer
Telegraphs revolutionized long-distance
communication by using either short or long
pulses to send messages in 2 to 3 seconds
across the world. This made life easier by
preventing long journeys to deliver letters. It
also gave people ideas on how to improve longdistance communication.
Agriculture
What other inventions improved
agriculture?
Answer
Some other inventions that improved
agriculture are the mechanical reaper and the
threshing machine. Cyrus McCormick’s
reaper, patented in 1834, cut ripe grain in
fields. The threshing machine separated
kernels of wheat from husks. Because the
Midwestern farmers grew food to feed
Northeastern factory workers, Midwestern
famers became a market for Northeastern
manufactured goods.
