Nor was Dick far behind, although perhaps not quite so plucky in venturing beyond his depth, now that he had no especial motive as on that memorable evening already alluded to by Hellyer the coastguardsman, for running the risk; while, as for Rover, he fairly revelled in the water, paddling round and round Bob and Dick, thereby executing a series of concentric circles never dreamt of by the Egyptian mathematician whose problems have been the torment of the boys of all ages.

The sea was so warm and pleasant that they stopped in such an unconscionable time as to necessitate the Captain’s hailing them three times to come out before they obeyed the order, and even then did so lothfully, making the old sailor sing out to them the more imperatively—

“Come out, come out of that, you young rascals!” he cried, shaking his stick menacingly. “If you are not out and dressed in five minutes, by Jove I’ll start without you; for, I can’t keep the ladies waiting. By Jove, I will!”

This threat had the desired result of quickening the boys’ movements; Dick, if the slowest in the water, being the sharper of the two in getting into his clothes. Rover was even speedier still, having only to give himself one good shake, administering in the action a shower-bath of drops to the Captain, when, there he was all ready, with a smart new curly black coat, glistening from his dip, as if he had just been to the hairdresser’s and had a brush up for the occasion!

On the way back to Mrs Gilmour’s house to breakfast, the Captain and Dick being specially invited this morning, so that they might leave together immediately afterwards for the steamer without losing any time, the boys had great fun with Rover and the towels.

These the retriever was always in the habit of carrying home, though Bob would not let him have them at once, right out, to take in his mouth as he left the beach.

He would first show them to Rover, with a “Look here, good dog!”

Then Bob would put the bundle of towels in a hole in the shingle, or under some big boulder, which did not improve them, by the way; Rover observing everything his young master did with the keenest attention, barking the while, and with every hair of his mane bristling with excitement.

After thus hiding the towels, if it could be called hiding where every detail of the operation was watched by the dog, Bob would, as he did on the present occasion, set out on his return across the common; Master Rover prancing in front of him, and anxiously keeping his speaking brown eyes fixed on his face, awaiting the order which he knew to be impending for him to go back and fetch the bundle left behind.

It was always a struggle for Bob to keep his countenance steady, the slightest suspicion of a smile being interpreted by Rover as an intimation that he was at liberty to “go and fetch,” without a word being uttered; and, this morning, the struggle was intensified by the presence of the Captain, who was in a joking mood, and tried all he could to draw off Rover’s attention from Bob.
