"He's an artful one, he is," he murmured admiringly. "I calls him Dizzy for short. What's your name, little un?" "Frank." "That sounds a good sort o' name too," said Barney; "sort o' name you see in gowld letters on a chany mug in the shop winders, don't it? I don't fancy, though, I could bring my tongue to it, not as a _jineral_ thing. I shall call yer `Nipper,' if you don't mind. After a friend o' mine." The new name appearing rather an advantage than otherwise under his present circumstances Frank agreed to drop his own, and to be henceforth known only as the "Nipper." This change seemed to have broken the last link which bound him to Green Highlands and his own people. He was Frank Darvell no longer; he belonged to no one; the wide world was his home; Barney and the white mice his only friends and companions. CHAPTER THREE. In the wandering life that followed, Frank had excellent opportunities for studying the character of his new comrade, and it did not take long to discover two prominent points in it. Barney was a liar and a thief. These accomplishments, indeed, had formed the principal features in poor Barney's education from his tenderest childhood. He had always been taught that it was desirable and proper to lie and steal; the only wrong and undesirable thing was--to be found out. To do Barney justice he very seldom _was_ found out; nimble of finger and quick of wit he had profited well by his lessons, and by the time Frank met him had long been a finished scholar, and able to "do" for himself. In spite of these failings he was a kind-hearted boy; he would not have hurt any living thing weaker than himself, and Frank's pale face and slender form soon appealed to his protective instincts in much the same way that his white mice did, for which he cherished a fond affection. If the night were cold he always managed that the Nipper had the warmest shelter, and when provisions were scarce the least tasty morsels were always reserved for himself, as a matter of course. Then what an amusing companion he was! How his ingenious stories, mostly a tissue of falsehood, beguiled the weary way, and made Frank forget his aching feet! He believed them all at first, and his innocent credulousness acted as a spur to Barney's fertile invention and excited him to fresh and wilder efforts. On one occasion, however, his imagination carried him beyond the limits of even Frank's capacity of belief, and from that moment suspicion began. He had been romancing about the riches and wealth of people who lived in London (where he had never been), and after describing at great length that the houses were none of them smaller than the whole town of Wickham put together, he added: "An the folks niver uses ought but gowld to eat an drink off." Frank looked up quickly.
