this canal."

"The Canal gives us a great advantage, doesn't it? I thought it doubled
the efficiency of our fleet?"

"It does nothing of the sort. The Canal may be seized. It may be put out
of commission for weeks or months by landslides or earthquakes. A few
hostile ships of the _Queen Elizabeth_ class lying ten miles off shore at
either end, with ranges exactly fixed, or a good shot from an aeroplane,
could not only destroy the Canal's insufficient defences, but could
prevent our fleet from coming through, could hold it, useless, in the
Atlantic when it might be needed to save California or useless in the
Pacific when it might be needed to save New York. If it happened when war
began that one half of our fleet was in the Atlantic and the other half
in the Pacific, then the enemy could keep these two halves separated and
destroy them one by one."

"I suppose you mean that we need two fleets?"

"Of course we do--a child can see it--if we are to guard our two
seaboards. We must have a fleet in the Atlantic strong enough to resist
any probable attack from the East, and another fleet in the Pacific
strong enough to resist any probable attack from the West.

"But listen to this, think of this," the veteran warrior leaned towards
me, shaking an eager fore-finger. "At the present moment our entire
fleet, if massed off Long Island, would be inferior to a fleet that
Germany could send across the Atlantic against us by many ships, many
submarines and many aeroplanes. And hopelessly inferior in men and
ammunition, including torpedoes."
