Various, Harper's Round Table, November 17…
“ THE RANGE-FINDER. Marvellous as the shooting has been, still more marvellous is the way it has been done. The gunners have fired without seeing, or even looking to see, the other ship. They have fired by looking rather at little dials close by each gun. They have aimed each gun without trying to see the enemy. Still, each shot goes straight to the mark, and the havoc is terrific. How is it all done? Long before the firing began you might have observed a sailor-man, half-way up each mast of the battle-ship, looking at the enemy through a telescope. ”
