The latter were both sending needless cannon balls in the direction of the chase, but not one of them came anywhere near her.
On the other hand, the highflyer and the St.Regis formed two angles of another triangle, the third of which was the point where they would come together, if nothing occurred to derange their relative positions.

By this time Paul Vapoor had developed all the power of the ship's boilers, and the screw was making more revolutions a minute than her highest record, which was found in a book the former chief engineer had left in his stateroom.
"I don't think that highflyer quite understands the situation, Mr.
Baskirk," said the commander, as he observed that she did not vary her course, and stood on to her destination, apparently with perfect confidence.
"I don't think she does, sir," replied the first lieutenant.

"She can see the American flag at the peak, and she knows what we are.

Doubtless she is making the mistake of believing that all the Federal ships are slow coaches." "Heave the log, Mr.Baskirk," added Christy, and he walked forward.
It was a matter of angles when it was desirable to come down to a close calculation, and the young commander found his trigonometry very useful, and fortunately not forgotten.

With an apparatus for taking ranges he had procured the bearing of the highflyer accurately as soon as the last course was given out, perhaps half an hour before.
