But education was stronger than instinct. It was the master. Before the lad’s eyes were his brother-officer and the men of the troop following; Sergeant Stubbs was carrying the keys, rushing right up to the magazine door—right, as it were, into the fire and the explosion which must occur; and nearly overhead was the room occupied by Hulton and the doctor.

Dick Darrell could not help his thoughts nor his natural instincts, whichever way they might lead. He had his duty to do as a soldier, and he neither hesitated nor shrank, but rushed forward to perform his task, meeting the two sentries, who had come hurrying down from the roof.

The next minute he was ascending the stairs leading to the officers’ quarters, reaching the broad corridor and the way into their sitting-room, thinking that it was a pity for that beautiful tulwar to be destroyed, when he fell over somebody on to some one else, sending a thrill of horror through his nerves as he heard deep groans.

“Who is it?” he cried.

A bright flash which came through the open door and window showed him the two servants, with their white cotton garments deeply stained with blood; while, as he gathered himself up, he found that something wet and warm had soaked his own thin silken garments, and his hands felt sticky.

The chill of horror came again. The two servants stabbed at the door; and not many yards farther lay Hulton’s room. Had he and the doctor been assassinated too?

Pity would have deterred him—duty urged him on; and the recollection of the terrible danger below, driven from his brain for the moment, came back as he dashed on, just as the door was thrown open and Hulton and the doctor hurried out.

“Who’s that? You, Darrell? What is it?”

“Fire—the magazine. Quick, for your lives!”

They hurried down the corridor, momentarily expecting the floor to open with the roar and red rush of an explosion; but they paused to seize the two men lying by the sitting-room door, and among them dragged them to the head of the stairs, and then to the bottom and out into the yard, where, as soon as they were in safety, Dick left the wounded with the doctor, and ran to where, in the midst of thick smoke, axe-blows were falling upon the entrance to the magazine.
