Description:
How did canals change America? We're glad you asked. No, really, we're glad you asked...otherwise, we would've spent a lot of time researching canals for nothing

By the 1830s Britain had over 4,000 miles of transportation canals
- 00:07
which made the U.S. pretty jealous. So, they decided to get in on the action. The [barge on a river]

Erie Canal which is really only mildly spooky, connected the Great Lakes and New
- 00:17
York City and yet cost seven million dollars to build but it earned over a

a big enough number for you then try this on for size.[cash shown]

some of the biggest canal barges in the US could carry over 230 tons. we realize
- 00:36
dollars and tons or different measurements but whatever you get the
- 00:39
point, canals are a big big deal. why? well here are some of the most important ways [map shown]
- 00:44
that canals changed America and other industrializing countries. first let's
- 00:49
look at the supplying industry. well the big push behind canals was the need to
- 00:53
move more goods farther away to supply growing industries .anyway the Industrial [man uses whiteboard for presentation]
- 00:58
Revolution was in serious need of some better transportation technology if it
- 01:02
ever wanted to be you know revolutionary. industries
- 01:05
couldn't grow without a steady flow of raw materials, and an easy way to
- 01:09
transport products ready for the consuming and the old techniques that
- 01:13
well just weren't cutting it. Horses and carriages don't exactly scream welcome [carriage shown]
- 01:18
to the modern world. yeah good thing too because horses
- 01:22
screaming at us would be just weird. well the agricultural boom also
- 01:26
increased America's need for canals. Most of America's canals connected the [farmer next to corn]
- 01:30
Midwest or South with major Eastern cities like Boston New York and
- 01:35
Philadelphia. that meant that Midwestern farmers could
- 01:39
suddenly produce goods that were bought in cities and farms started to get [people gather in front of a barn]
- 01:43
bigger and more profitable. Plus cities could get bigger without worrying about
- 01:47
the rising costs of hauling in food from the rural countryside. That agricultural
- 01:52
boom convinced a hefty number of people that their future was in farming the
- 01:56
Midwest. And as the population grew more people emigrated westward. Wasn't Cowboys
- 02:02
that settled wild Iowa, it was canals. not quite as exciting we [men sit on horses]
- 02:07
know also this is wild Iowa oxymoron well anyway America's canal era
- 02:12
lasted about 50 years if just like your beloved pet goldfish it was only with us
- 02:17
for such a short time, transportation technology took a big leap and left [fish in a bowl]
- 02:22
canals and barges in the dust .of course all techniques that we put to the test
- 02:27
in building smaller canals were used a little later on in a huge projects. We're
- 02:32
talking about that thing called oh yeah the Panama Canal in 1914 and the [map of panama shown]
- 02:38
Suez Canal in 1869 well the Panama Canal slices straight
- 02:43
across Panama and lets ships go between North and South America rather than all
- 02:48
the way around the tip of Chile. well meanwhile the Suez Canal goes through
- 02:52
the tippity-top of Egypt and less ships go between Europe and the Indian Ocean
- 02:56
without sailing all the way around Africa. even today both of those canals
- 03:01
are used constantly ,which probably has led both canals to tell their therapist. [man stands between canals]
- 03:06
we feel so used. that's a good thing
