I wish we could see down into the battery itself, but it is too high for that." The Doctor lay looking along his rifle.

Presently he fired, and as if it had been the signal five cannon boomed out almost at the same moment, the other being fired a quarter of a minute later.

Three of the shot struck the house below the parapet, the others went overhead.
"I hit my man," the Doctor said, as he thrust another rifle through the loophole.

"Now, we will see if we can keep them from loading." Simultaneously with the roar of the cannon a rattle of musketry broke out on three sides of the house, and a hail of bullets whistled over the heads of the defenders, who opened a steady fire at the embrasures of the guns.

These had been run in, and the natives could be seen loading them.
