PELTON'S LEGACY
Congratulations on "Eureka! 25
brilliant California Ideas" (January/February
2007). [However], from a source outside of the
Moore family and from within it, I have learned
that Joseph Moore [rather than Lester Pelton]
conceived of the idea of a more efficient bucket
for waterwheels and presented the concept to a
professor of engineering at Berkeley, who provided
technical expertise. Moore was an immigrant
from Scotland who arrived in California
in 1849, skilled in engineering and the mechanical
arts. He became the superintendent of the
Risdon Iron Works of San Francisco. In this
capacity he played a very important role in
designing, building, and installing machinery
for the silver mines of Virginia City, Nevada,
and for a wide range of hydraulic machinery,
including the first elevator on the Pacific Coast
for the Palace Hotel of San Francisco. Although
he was extraordinarily successful as an inventor,
he felt that inventions should be for public
use and benefit, and thus he did not patent
his waterwheel.
James R. Moore '33
Lester Pelton tested between 30 and
40 different shapes, combinations, and locations
of buckets before deciding on the best,
which was two curved buckets, which slit the
stream of water. He brought the pattern of his
waterwheel to the University of California in
1883, where a hydraulic model was made and
tested at the University’s College of Mechanics.
In his report on the tests under Professor
F. G. Hesse, Ross E. Browne said, "Pelton furnished
a pattern from which buckets were cast,
and thirty of them attached to the wheel.…
The angle [of the buckets] is just sufficient to
provide against interference of the discharged
water with the buckets following.… Experiments
were first made with seven different settings
of the nozzle.… It is plain that the Pelton
Wheel, besides giving a higher efficiency than
the partial turbine, is more easily built, has a
decided advantage in the setting of the nozzle,
and is not so dependent on the precise size of
the nozzle used."

WILSON WON!
from the January/February issue (page
23) we learn that California Proposition 187
was the "worst shot heard ‘round the political
world"supposedly because only 27 percent
of the Latino voters supported it, and somewhere
between 70,000 and 250,000 marched
against it. (Tellingly you default to the largest
number.) According to the formulation
in the item Pete Wilson was made to suffer.
However, you are ignoring the fact that Wilson
soundly beat Kathleen Brown in that very same election and Proposition 187 won with
58.8 percent of the vote. Wilson didn’t lose
his mojohe lost his voice while running for
the presidency.

TEEN LIT
I enjoyed reading Rebecca Ruiz’s article
in the January/February issue on Francesca Lia
Block, ’86 ("Telling teen stories"). As a fan of
Block’s novels, and of young adult literature
in general, I was delighted to see the attention
given to this wonderful writer who is so
respectful of, and loved by, teens. However,
there was one error. The Margaret A. Edwards
Award for lasting and significant contribution
to young adult literature is awarded by
the Young Adult Library Services Association
(YALSA), the fastest-growing division of the
American Library Association. Interested persons
can learn more about the award at www.ala.org/yalsa/edwards.

BATTLE OF THE BIKES
Erik Vance is to be commended for his
excellent bit on mountain bikes in the January/
February issue’s "Inventing California"
section ("Xtreme Cyclist"). Unfortunately he
fails to note the pioneering role in that saga
of John Finley Scott, a University of California,
Davis Professor and UC Berkeley Ph.D.
Quoting Michael Fitzgerald writing in the
Stockton Record, "The Mountain Bike Hall of
Fame credits him [Scott] as ‘probably the first
mountain bike enthusiast in the United States.’"
Others flat-out call him "the father of the
mountain bike." To a Schwinn frame in 1953
Scott added not only balloon tires but also flat
handlebars, derailleur gears and cantilever brakes
to create what he called a "Woodsie Bike." His
invention was one of the major steps in the
development and popularization of an all-terrain
bicycle that revolutionized buttoned-down
cycling. Professor Scott appears to have been
murdered in his home last June. This is a loss
mourned not only by all that knew him [or]
benefited from his creative mind and pioneering
spirit.

REFORMING HEALTH CARE
Congratulations on your article
"Beyond the silver bullet" in the (January/February)
issue. It is very helpful in sorting through
the multiple arguments (and illusions) that now
populate the health care discussion. Perhaps it is
also a reminder that good sense in the solution
of social problems is not likely to be ideologically
exciting.

POLK HONORS
In our September/October 2006 issue, "Global Warning,"
graduate students from Berkeley Graduate
School of Journalism contributed stories from five
climate change hotspots around the worldfrom
glacial melting at Mount Kilimanjaro to flooding in
Bangladesh and the Pacific island of Tuvalu to the
loss of algae in Tanzania’s Lake Tanganyika. In February,
the students and their project were honored
with the George Polk Award, one of journalism’s
highest awards, for a radio version of the reports
broadcast on NPR. The students, from a class led
by investigative reporter Sandy Tolan and climatologist
John Harte, included Pauline Bartolone,
Alexandra Berzon, Kate Cheney Davidson, Durrell
Dawson, Jori Lewis, Felicia Mello, Nick Miroff, Jon
Mooallem, Emilie Raguso, Aaron Selverston, and
Sandhya Somashekhar. They make us proud.
