There’s an old folk song that goes,
“Well, she’s gone, gone, gone, and
she’s gone, gone, gone. I lost my true
love on the Raging Canal.” Back in
the 1840s, a bunch of local
Connecticut businessmen decided,
after seeing how well the 1825 Erie
Canal was going, that a canal could enable
commerce between Hartford and the upper
Connecticut River.
Steamboats could get around the rapids
at Enfield, using this canal, which would
also provide water for businesses along the
5-mile route. The businessmen ran this
canal for many years. Of course, 150 years
later, the canal was in some disrepair. I
looked into this and decided I would like to
canoe down it.
SIGN? WHAT SIGN? • My sister said that there seemed to
be a sign saying “Boating Prohibited.” But I have never seen
this sign. I know that many bicyclists are unable to read. If
a sign says “Bikes Keep Out,” the riders cannot read it. On
they proceed.
Well, if I went to that canal at midnight, I could not
read or see such a sign, either. Too dark? Maybe we
could ease into the canal at 11 p.m. and get to the far
end and out before anybody noticed. We did some research
and reconnoitering. After all, in the 1970s, the canoeing
guidebooks plainly said, “Take the Canal and avoid
the dam and rapids at Enfield.”
In the central part of Connecticut, where I grew up,
we had lots of mills, and originally they ran by water power.
So there were little canals fetching the water from a high
pond to the waterwheels at the mills. Knitting mills, spinning
mills, weaving, and even envelope-making mills.
As we learned in the third grade, the “fall line” was where
the streams had a large dropoff and were able to generate
a LOT of water power. Even when steam or electricity
replaced water power, many mills needed a large flow of water
for certain kinds of washing and processing. The water
downstream from the mill often smelled quite soapy or oily.
So mills were a major feature of most towns. If there wasn’t
a mill, there wasn’t a town—the economics of the 1800s. The
Windsor Locks Canal did not have a LOT of flow, or a LOT
of dropoff, but it was a fairly reliable water supply.
INFILTRATION AND EXFILTRATION • There’s no easy road
access to the canal, so we would have to kayak down the
river to get to the old canal guard locks (inlet locks). By the
light of the full moon? Maybe when the moon has nearly
set... to avoid alerting the militia. Muffled oars, and all that.
We did enough scouting to pinpoint the trees that had
fallen across the canal and indicate where we might have
to wade over silt bars. This handsome old canal had nearly
vertical stone or concrete banks, so we would need rope
ladders to get up and down the walls. We brought
rope ladders and
grappling hooks. Life
vests were de rigueur.
But where were
we going to take the
canoe back out of the
canal? If we got to the
foot of the canal, a steep
slide would get us back
to the Connecticut—
and we could take out on
the opposite east bank.
Not such a bad deal, in
weak moonlight. September
is a time of low flow, so the currents would not be nasty
or dangerous. I would hate to be pushy. We were not pushy.
I did not “lose my true love” on the “Raging Canal.” A
canal like this is substantially flat-water. Not boring in terms
of 160 years of history, nor in terms of challenges. Just flat.
FINANCIAL FLOOBYDUST • Switching gears, Alan Greenspan
has admitted that he screwed up and had a bad model
for the economy. He claims he misunderstood what was
going to happen. What did Spice suggest for him to do? I
coulda told you that Greenspan was not doing a good job on
his PID controller.
He waited too long to start decreasing the interest rates,
and then he decreased them too slowly. I noticed that at the
time! Then, by leaving the interest rate at 1% for too long, he
got the ARMs to start out too low. And then when the rates
went up, the subprime mortgage holders got whip-sawed.
This is exactly how you make a limit-cycle oscillator! In
other words, Mr. Greenspan did not have enough D (derivative)
term in his controller, and he failed to anticipate new
problems. And he had too much gain in the I (integral)
path. I can do this any day, on my bench, but I don’t destroy
a nation’s economy.
No, I don’t want to take over Greenspan’s job. I don’t
want that job. But I could still do it less badly.
