MY DEAR LAD,

You have now completed your book learning, and it is time to fill your own kettle with rice, as we say. With approval of your guardian, I have obtained for you a post in the great company of Ehrlich Söhne, who have manifold activities, and lots of branches in all parts of China. With them you will gain valuable experience of intrinsic excellence. You will not be blind fowl picking after worms. Your friend Mole is to come to China next month; I vote you come with him, for pleasant company shortens the longest road. You will have liberal allowance for outfit, for as your proverb says, do not spoil ship for ha'porth of tar. Until I see you, then, I write myself your true friend,

TING CHUH.

No boy likes to leave school, but the regrets of the two friends were tempered by their anticipation of novel scenes and fresh experiences. They were delighted at the prospect of going out together, and found themselves looking forward eagerly to the end of the term. One day an advertisement of the North German Lloyd caught Errington's eye.

"I say, Moley, I vote we go out on a German ship," he said to Burroughs. "It will be a jolly sight more interesting than a British ship, and we shall get a good deal of sport in studying the funny foreigner."

Burroughs agreed, and in due time they booked their passage on the Prinz Eitel Friedrich. It did not occur to them that the "funny foreigner" might also find some interest in studying them; but after certain exciting experiences which befell them during the next two years, they remarked on the strange consequences that came of a single advertisement in the Times.

They joined the vessel at Plymouth, and would perhaps have attracted no attention among their fellow-passengers but for a somewhat unusual object among their belongings. Burroughs, unlike Errington, had always enjoyed plenty of pocket-money, and being fond of boating, he had bought first a skiff for use on the river during holidays and then a small motor launch. Just before leaving school he had happened to see a hydroplane in the Solent, and it occurred to him that he and Errington, when they got to China, would find such a vessel useful, or at least exciting, on the Yang-tse-kiang. Accordingly he exchanged his launch for a small speedy hydroplane of the best type: and the novel vessel aroused a certain curiosity in some of the passengers as they saw it lowered into the hold.

For a day or two after quitting port they kept pretty much to themselves, exchanging notes about their fellow-passengers, and finding some amusement in watching their deportment in the dining-saloon. One man in particular engaged their attention. He was a German of florid aspect, with hair cut short and standing up brush-like, and a thick brown moustache which he evidently took some pains in training à la Kaiser. This was not so uncommon as to mark him out for special notice; but the boys observed, after a few days, that this man, though possessing the most engaging manners, seemed to be somewhat shunned by the rest of the German passengers. They did not actually cut him, but they appeared to hold themselves aloof. He belonged to none of the sets into which passengers on a long voyage invariably split up; he was never invited to join their card-parties. The vague impression formed by the boys was that the Germans felt a sort of distrust for their compatriot. The only man on board who appeared to admit him to terms of intimacy was a German major-general who was proceeding to Kiau-chou, the German settlement. These two were often to be seen of an evening under the awning on the foredeck, remote from the other passengers, conversing in low tones, though with no appearance of secrecy.

One evening, after dinner, the boys were leaning over the rail, idly watching the incandescent play upon the surface of the sea, when the German sauntered past them, turned, and made a pleasant remark about the charming weather. He spoke English very well, with scarcely anything to reveal his nationality except the customary difficulty with the th. There was something attractive about the man, and Errington, seeing that he seemed disposed to continue the conversation, offered him a cigarette, and invited him to place a deck-chair beside those which the boys had opened for themselves.

"I zink I may almost call myself an old friend," said the German. "Am I mistaken, or are you ze son of ze late Mr. Herbert Errington, of Shanghai?"
