ne_."

"Well, in the name of Atlas, what island is it, then?" roared Holmes,
angrily. "What is the matter with all you learned lubbers that I have
brought along on this trip? Do you suppose I've brought you to whistle up
favorable winds? Not by the beard of the Prophet! I brought you to give me
information, and now when I ask for the name of a simple little island
like that in plain sight there's not one of you able so much as to guess
at it reasonably. The next man I ask for information goes into irons with
Judge Blackstone if he doesn't answer me instantly with the information I
want. Munchausen, what island is that?"

"Ahem! that?" replied Munchausen, trembling, as he reflected upon the
Captain's threat. "What? Nobody knows what island that is? Why, you
surprise me--"

"See here, Baron," retorted Holmes, menacingly, "I ask you a plain
question, and I want a plain answer, with no evasions to gain time. Now
it's irons or an answer. What island is that?"

"What did you live on during that year?" asked Holmes, eying him narrowly.

"Canned food from wrecks," replied the Baron, feeling much easier now that
he had got a fair start--"canned food from wrecks, commander. There is a
magnetic property in the upper stratum of this piece of derelict real
estate, sir, which attracts to it every bit of canned substance that is
lost overboard in all parts of the world. A ship is wrecked, say, in the
Pacific Ocean, and ultimately all the loose metal upon her will succumb to
the irresistible attraction of this magnetic upper stratum, and will find
its way to its shores. So in any other part of the earth. Everything
metallic turns up here sooner or later; and when you consider that
thousands of vessels go down every year, vessels which are provisioned
with tinned foods only, you will begin to comprehend how many millions of
pounds of preserved salmon, sardines, _pate de foie gras_, pea
