e and fleet tactics. To be
sure, he himself did not know how to splice a rope or furl a sail; and,
owing to his partiality for strong coffee, he was apt to be nervous
when we fired salutes; yet all this did not prevent him from delivering
lectures on cannonading and "breaking the enemy's line."

He had arrived at his knowledge of tactics by silent, solitary study,
and earnest meditation in the sequestered retreat of his state-room.
His case was somewhat parallel to the Scotchman's--John. Clerk, Esq.,
of Eldin--who, though he had never been to sea, composed a quarto
treatise on fleet-fighting, which to this day remains a text-book; and
he also originated a nautical manoeuvre, which has given to England
many a victory over her foes.

Now there was a large black-board, something like a great-gun
target--only it was square--which during the professor's lectures was
placed upright on the gun-deck, supported behind by three
boarding-pikes. And here he would chalk out diagrams of great fleet
engagements; making marks, like the soles of shoes, for the ships, and
drawing a dog-vane in one corner to denote the assumed direction of the
wind. This done, with a cutlass he would point out every spot of
interest.

"Now, young gentlemen, the board before you exhibits the disposition of
the British West Indian squadron under Rodney, when, early on the
morning of the 9th of April, in the year of our blessed Lord 1782, he
discovered part of the French fleet, commanded by the Count de Grasse,
lying under the north end of the Island of Dominica. It was at this
juncture that the Admiral gave the signal for the British line to
prepare for battle, and stand on. D'ye understand, young gentlemen?
Well, the British van having nearly fetched up with the centre of the
enemy--who, be it remembered, were then on the starboard tack--and
Rodney's centre and rear being yet becalmed under the lee of the
land--the question I ask you is, What should Rodney now do?"

"Blaze away, by all means!" responded a rather confident reefer, who
had zealously been observing the diagram.

"But, sir, his centre and rear are still becalmed, and his van has not
yet closed with the enemy."

"Wait till he _does_ come in range, and _then_ blaze away," said the
reefer.

"Permit me to remark, Mr. Pert, that '_blaze away_' is not a strictly
technical term; and also permit me to hint, Mr. Pert, that you should
consider the subject rather more deeply before you hurry for
