In Fayal they pointed out a hill and told him it was 800 feet high and 1,100 feet long.

And they told him there was a tunnel 2,000 feet long and 1,000 feet high running through the hill, from end to end.

He believed it.

He repeated it to everybody, discussed it, and read it from his notes.
Finally, he took a useful hint from this remark, which a thoughtful old pilgrim made: "Well, yes, it is a little remarkable--singular tunnel altogether--stands up out of the top of the hill about two hundred feet, and one end of it sticks out of the hill about nine hundred!" Here in Gibraltar he corners these educated British officers and badgers them with braggadocio about America and the wonders she can perform! He told one of them a couple of our gunboats could come here and knock Gibraltar into the Mediterranean Sea! At this present moment half a dozen of us are taking a private pleasure excursion of our own devising.
