They happened to meet a medical missionary and his wife who had just arrived from England. To them they handed over £2000 on condition that they would use it for the good of the natives south of the Yo. And when, after a month's rest, they returned to the scene of their adventures, they were accompanied by the missionaries and a new band of Hausa boys, with John again as headman. The old band felt so rich on the generous pay they had received that they meant to retire from business, at least for a time. John treated them with contempt. "Plenty silly chaps," he said. "Dey hab got lots of cash; me savvy all same. What dey do? Spend, spend, spend all time. Bimeby all gone. What do den, sah? Dey want 'nother massa; no can find one. Dey go sick. Wah! Me hab got good massa; me savvy all dat, sure 'nuff." When Royce and Challis were last heard of they were working a rich tin mine, with two hundred contented negro labourers in their employment. A little settlement had sprung up in the midst of the great plain, with two large bungalows, one for Royce and Challis, the other for the missionary and his wife, and a number of neat grass huts for the labourers and their families. The country in their immediate neighbourhood was troubled no more by the Tubus. A brisk trade grew up between their settlement and the surrounding villages, and once a year the people for miles around go in procession to visit the white men, carrying presents for the strangers who saved them from the raiders and brought peace and prosperity to the countryside. THE END HERBERT STRANG'S STORIES _SOME OPINIONS_ "I envy the boy or girl who is given a Herbert Strang book.... Mr. Strang's powers of invention are great. One is hurried along breathlessly from one adventure to another, till we are left gasping at the end of the jolly narrative.... Mr. Strang's books are full of the qualities to which boys--and girls--should aspire. Reading him, an older, less adventurous person 'lives by admiration.'"--KATHARINE TYNAN. "The intellectual level of boys' stories has been materially raised by Mr. Strang, and at the same time he has infused into them a stronger human interest than the old writers did. The gain is an all-round one.... Mr. Strang has brought the boys' story up to the same level of artistic effort and realisation as the high-class novel."--JAMES BURNLEY. "We rejoice to find that among the crowd of money-makers who produce as if by machinery the standard book for boys, there are still some who realise that because only a boy is to read a book it need not therefore be careless, and because the boy will be without experience the book need not therefore be impossible."--THE OUTLOOK. "Mr. Strang's books suggest a standard by which very few writers of boys' books will bear being judged. The majority of them are content to provide their young friends with mere reading--Herbert Strang offers them literature."--THE GLASGOW HERALD.
