MAKING "THE DIRT FLY" LOCKS CONSTRUCTION
1904-1906 |
|
Shortly
after ascending to the presidency, Theodore Roosevelt spoke of the
Panama Canal in a speech to Congress. "No single great material work
which remains to be undertaken on this continent, "Roosevelt said, "is
as of such consequence to the American people."
Roosevelt acted quickly.
In 1902, the United States reached an agreement to buy rights to the
French canal property and equipment for a sum not to exceed $40 million.
The U.S. then began
negotiating a Panama treaty with Colombia. Roosevelt made construction
of the canal a priority, announcing his intention to make "the dirt fly"
in Central America.
The first ICC
chief engineer was John F. Wallace, who was a railroad engineer and
general manager of the Illinois Railroad when he took the job to build
the canal.
He arrived in
Panama to take over from acting chief engineer Major Black in July 1904,
but he resigned a year later. He was fearful of the yellow fever threat
and attracted by a better paying job in the United States. Railroad
engineer John Stevens, an executive with the Chicago, Rock Island, and
Pacific Railroad, replaced Wallace and arrived in Panama in July 1905.
He remained longer than Wallace and was successful in building a solid
infrastructure that included worker and family quarters.

Chief
Engineer John Stevens, a veteran of railroad construction in
the Rocky Mountains, recognised that the challenge of the
canal was simultaneously one of excavation and
transportation. Rock had to be moved from the mountains,
where it blocked the canal, to the river delta, where it
formed the core of the new Gatun Dam. His railroad
excavation system functioned like a conveyor belt with the
trains carrying the dirt from the steam shovels directly to
the dump sites. The mainstay of the construction effort was
the 95-ton, track-mounted, Bucyrus steam shovel. Six million
pounds of dynamite per year blasted the hundreds of feet of
basalt that blocked the route. At the peak of the
construction effort, 25,000 men removed a million cubic
yards of material every day. This massive excavation
capability was balanced with dumping capacity, using a
complex rail system of one-sided flatcars that hauled away
200 trainloads of excavated material daily. As the digging
progressed, enormous track shifters moved the rail lines to
the main areas of excavation.
Stevens was ready to dig in 1906, but the type of canal -
sea-level or lock - remained a question. Wallace had
recommended a sea-level canal, but Stevens favored a lock
canal. A 13-member board of consulting engineers
recommended, by an 8-5 margin, a sea-level canal, but the
ICC accepted the minority report for a lock canal written by
retired Army engineer Brigadier General Henry L. Abbot. The
plan President Roosevelt signed into law in June 1906 called
for a canal with three locks on the Atlantic side, three on
the Pacific side, and a lake in the middle created by
damming the Chagres River at Gatun.
Stevens never
got very far with this plan because he resigned in February
1907. His strength was as a railroad construction engineer,
and by 1907 the conveyor-belt-type railroad system was in
place. What awaited Stevens was hydraulic engineering: the
design of dams and locks and the large scale use of
concrete. That was not his strength, but it certainly was
the strength of Army engineers in the U .S. Army Corps of
Engineers. Thus, it was to the Corps that President
Roosevelt looked to get someone who could not quit.

ROOSEVELT'S VISIT TO PANAMA CANAL
1906 |
|
In the
fall of 1906 President Theodore Roosevelt visited the Canal
Zone. He was the first American president to visit a
foreign country. Panama Hats took off in production in
the middle of the 19th century. For the construction
of this amazing project, Panama Hats were crucial. The
environment where the construction crew of the Panama Canal
worked was hot and humid. Sunny days made Panama Hats a
daily must wear head gear and some of the finest woven hats
could even hold water to refresh the hard workers digging
out tons of earth. Theodore Roosevelt fell in love with
these hats while visiting the construction of the Canal in
1906. His picture wearing a fine "Panama Hat" appeared in
The New York Times.

Theodore
Roosevelt's visit to Panama in 1906 |
|
|

On 18 February, Roosevelt summoned Army engineer Major
George W. Goethals to the White House for an interview and,
on 26 February, he announced that Goethals was going to
Panama as chairman of the ICC and chief engineer to complete
construction of the Panama Canal . As a member of the Army
General Staff, Major Goethals had accompanied Secretary of
War William Howard Taft to the Canal Zone in 1905 to
recommend sites for coast defense fortifications.
In 1907 Goethals was 47 years old and had almost 30 years
experience as an officer in the Corps of Engineers. Upon
graduation from West Point in 1880, he entered the Corps and
began a career of river-and-harbor and lock-dam construction
work on the Ohio and Tennessee Rivers, canal work at Muscle
Shoals, and coast defense construction work in New England.
If any one person can be credited for this achievement it is
George W. Goethals, the project's chief engineer, 1907-1915.
The first two chief engineers, both civilians, resigned
after short tenures. President Theodore Roosevelt announced
that the next chief would be an Army officer, who, if he
walked off the job, would find himself facing a court
martial. The man selected was Major George W. Goethals of
the U.S. Army Corps of Engineers.
As a
member of the Isthmian Canal Commission Goethals visited the
Canal Zone in 1905. He so impressed Roosevelt and Secretary
of War William Howard Taft that they chose him for the chief
engineer's position after the resignation of the second
chief, John F. Stevens. Stevens had been much loved by those
who had been laboring on the Canal. They worried that
Goethals (soon to be Lieutenant Colonel and later Colonel)
would impose a military regime. He dispelled these fears by
appearing only in civilian clothing and inviting all workers
to talk freely with him regarding any grievances. Goethals
reported only to the president and secretary of war, who
placed few limits on his powers.
Promoted to Lieutenant Colonel in March 1907, Goethals took
with him to Panama as members of the ICC two other Army
engineers, Majors David Gaillard and William Sibert. Both
were members of the West Point class of 1884. Gaillard was
serving on the General Staff with Goethals and had
experience in river-and-harbor work, while Sibert had a
river-and-canal work background. Goethals placed Army
engineer Major Harry F. Hodges in charge of the ICC office
in Washington, DC, where he could use Corps personnel
throughout the United States to help select and inspect
equipment to be sent to the Canal Zone. Goethals initially
organized the canal work by type, putting Gaillard in charge
of excavation and dredging and assigning Sibert to
lock-and-dam construction.
After
several months of observation, Goethals was ready to make
some changes. In late 1907, he moved the two Sosa Hill locks
on the Pacific side inland to Miraflores because of the
threat of naval bombardment. He brought Hodges to Panama as
assistant engineer in charge of lock design and replaced him
in Washington with Army engineer Major Frank C. Boggs. He
widened the bottom width of the Culebra Cut, a channel
through the Culebra Mountain in the Continental Divide, from
200 to 300 feet; and, on the recommendation of the Navy,
increased the lock widths from 100 to 110 feet.
Traveling in a railroad car known as the "Yellow Peril,"
Goethals regularly oversaw the work at the various
construction sites. These included two dams, six sets of
locks, two artificial lakes, regulating works, entrance
channels, breakwaters, telephone and telegraph systems, a
hydroelectric station, a rebuilt railroad, and the
excavation of the challenging Culebra Cut.
