"I'll leave the moke at a blacksmith's, and while the thing's being shod I may as well call and see Betty," he decided, and proceeded to put his plan into execution by enquiring of one of the attendant throng--he suffered their presence with equanimity by this time--where a shoesmith was to be found. "Fine animal, sir," remarked the smith. "Best I've seen for a long time. Won't hurry, eh? Well, p'raps 'tes not being shod. How long will it take? Say half an hour." Billy deliberated. It was not much use going to "Mill View" if he had to be back in thirty minutes. On the other hand he could easily put up the animal at Two Elms and save time on the return journey. Besides, curiosity prompted him to watch the forthcoming operation. The smith was a powerfully-built fellow from his waist upwards. His chest was of enormous depth, his breast and arm muscles stood out like the gnarled trunk of a tree. But his lower limbs were so thin that they seemed incapable of supporting the bulky "upperworks." Butterfly submitted graciously to the initial stages of the operation, but when it came to shoeing the off-side fore-foot she exhibited signs of obstinacy. "I'll have to throw her, sir," declared the smith. "Stand aside a bit." Bending he gripped the donkey's legs and applied his huge bulk to her ribs. Like a felled ox Butterfly fell. "Keep 'er 'ead down, sir," cautioned the smith. "I won't be long." At length the last shoe was nailed on and filed smooth. Billy had had about enough of it, for the pungent smell of the forge was far from pleasant. But not so Butterfly. Apparently smarting under the indignity she refused to rise. The smith applied a leather strap, but unavailingly. He gripped her head and tried to lever it up. The donkey lashed out, narrowly missing Billy's shins. "Dunno as 'ow I seed such a brute afore," said the smith, scratching his head. "Look 'ere, sir; do you 'old her tail and pull, and I'll tackle her 'ead. Now, up you come." Butterfly did. With a series of frantic kicks she regained her feet, sent the astonished smith flying in one direction and Billy in another. For some seconds the flight-sub was too dazed to take any active interest in the sequence of events, but when at length he picked him self up and ran to the smithy door, Butterfly's heels were just visible as at a good fifteen miles an hour she disappeared round the corner of the street. CHAPTER XV RECALLED BY WIRE "SHE'S off home, sir," said the smith. "Don't you fash yousen about 'er. The cart? Run it in 'ere. 'Twill be all right." Billy paid for the shoeing and walked slowly down the street. "No good going to see Betty at lunchtime," he soliloquised. "Might just as well see about something to eat."
