"Now then: swords.

Steady! Forward!" "Now!" whispered Dummy; and as the men tramped on to the bridge for their renewed attack, Mark struck the steel with his flint, and a tiny spark or two fell.
"Quick--another!" whispered Dummy, and the men halted in the middle of the bridge.
"Forward!" shouted the captain from the rear; "what are you halting for ?" "What's this here ?" growled one of the men in the first line, for he had caught sight of the powder-bag lying in the middle of the pathway, his question taking off his comrades' attention from the two sharp clicks which came from behind the lesser gateway.
But they saw a little line of light and smoke running over the stone paving of the bridge, and with a yell of horror, they turned and fled hurriedly back and down the slope.
"Don't look!" yelled Dummy, forcing Mark aside, when the flash brought the castle and summit of the Black Tor into full view; then there was an awful muffled roar, which went echoing away, and as it died out, the two lads dashed across the bridge to the head of the zigzag descent, to make out by hearing that the enemy were in full retreat.
"I think that settled 'em," said Dummy quietly.

"You did it fine, Master Mark." "Hoi! Who's there ?" cried a voice behind them.
"Dummy Rugg, father." "And you, my boy?
Thank Heaven! I was afraid something was wrong." "Then it was you two with my powder," cried another voice out of the darkness.
"Yes, Dan Rugg, and a splendid use they made of it," cried Sir Edward.
"Well done, my lads.

But come into shelter; they surprised us, with everything left open.

We must lock the stable door now.
