The other man also recognised him at the same time, releasing the old man equally hurriedly.

“Beg pardon, sir,” he said. “Didn’t know it wer’ you, sir!”

But the Captain made no reply to this apology.

He only pointed to the water just below where they were standing, and where the head of Rover could be dimly seen in the gathering dusk of the evening, now rapidly closing in, splashing his way to the shore.

“Boys—save—quick—drown!” he stammered out brokenly. “Quick, quick!”

The men did not require any further explanation or incentive.

Without stopping to doff a garment, in they both plunged, boots and all; and, before the Captain knew that they were gone from his side, they had reached poor Rover, now quite exhausted, gallant dog though he was!

Then, one of the men grasping hold of Bob and the other catching hold of Dick, they swam with the two boys between them, still locked together, to the end of the rampart wall that jutted out over the water.

Here the Captain was ready and waiting to lean over and lend them a hand, keeping the while a steady purchase to his feet by the aid of his malacca stick, which possibly had never been of such service before; and, presently, the coastguardsmen, the boys, and Rover, who would not let go his young master’s collar and was lifted out along with him, were all once more again on firm ground.

By this time, a small crowd of spectators had collected on the spot, composed principally of persons who had come out for a walk round the castle and had their attention arrested by the scene passing in the water below.
