"I shall be glad to serve under him," he said.

So it was arranged, and several hours later the two lads found themselves aboard the German steamer Lena. For the first time in his life Jack trod the bridge of his own ship, and he could not but be proud of that moment; Frank, too, was elated at his good fortune.

With this parting injunction, Captain Marcus dropped over the side of the Lena:

"Make straight for London. Although you carry some guns, if attacked do not fight back unless absolutely necessary. Show the enemy your heels, if possible. However, if you do have to fight, fight as the true sons of Great Britain."

"We shall, sir," replied both lads grimly, and Captain Marcus realized that he could not have put the ship in better hands.

From among the crew Jack now selected a sailor named Jennings for second officer, and another by the name of Johnson for third officer. There was a hissing of steam from below, slowly the cable was loosened, and the Lena put off down the river.

The two British commanders followed in small boats. At the entrance of the river the steamer slowed down, and the boys watched the two commanders go aboard their respective cruisers.

A moment later guns on both ships boomed loudly. It was a salute, carrying a cheery "Good luck" to the ears of the two lads. As they sailed out to sea they could perceive that the cruisers also were getting under way, and were heading in the same direction as the Lena.

The Lena quickened her pace and sped off toward the north, heading for the open water. Night fell and still she steamed rapidly on, the cruisers following in her wake.

Frank took the first watch, and Jack turned in. The sea was perfectly smooth and the Lena steamed on, rolling gently on the even swell of the waves.
