Then he found a letter on Harold's bed. It said (and it was blotted with tears, and it had a blob of glue on it):
'Dear Billy,
'It wasn't my fault about your essay, and I'm sorry, and am going to run away to India to find my people. I shall go disguised as a stowaway.
'Your affectionate cousin,
'Harold Egbert Darwin St. Leger.'
Billy did not have to show this letter to his mother, because she had gone away for the day, so he did not have to explain to her what a beast he had been. If he had had to do this, it would have been part of what is called Expiation.
Then he got the farm men to go out in every direction, furnished with a full description of Harold's silkworm-like appearance, and Billy borrowed a bicycle from a noble-hearted butcher's boy in the village and set out for Plymouth, because that seemed the likeliest place to look in for a cousin who was running away disguised as a stowaway. The wind blew straight towards the sea, and it occurred to Billy—he deserves to be called Billy now, I think—that the great patent kite, which was ten feet high, would drag him along like winking if he could only set it flying, and then tie it to the handle-bar of the bicycle. It was rather a ticklish business to get the kite up, but the butcher's boy helped—he had a noble heart—and at last it was done. Billy saw the great bird-kite flying off towards Plymouth. He hastily knotted the string to the bicycle handle, held the slack of it in his hand, mounted, started, paid out the slack of the string, and the next moment the string was tight, and the kite was pulling Billy and the bicycle along the Plymouth road at the rate of goodness-only-knows-how-improbably many miles an hour.
At last he came to the outskirts of Plymouth. I shall not tell you what Plymouth was like, because Billy did not notice or know at all what it was like, and there is no reason why you should. Plymouth seemed to Billy very much like other places. The only odd thing was that he could not stop his bicycle, though he pulled in the kite string as hard as he could. He flew through the town. All the traffic stopped to let him steer his mad-paced machine through the streets, and tradespeople, and people walking on business, and people walking for pleasure, all stopped with their respectable mouths wide open to stare at Billy on his bicycle. And the kite pulled the machine on and on without pause, and at a furious rate, and Billy, in despair, was just feeling in his pocket for his knife to cut the string, when some mighty sky-wind seemed to catch the kite, and it gave a leap and went twenty times as fast as it had gone before, and the bicycle had to go twenty times as fast too, and before Billy could say 'Jack Robinson,' or even 'J. R.,' for short, the kite rushed wildly out to sea, dragging the bicycle after it, right slap off the edge of England. So Billy and the butcher's boy's bicycle were dragged into the sea? Not at all. They were dragged on to the sea, which is not at all the same sort of thing. For the kite was such a very extra patent one, and so perfectly designed and made, that it was just strong enough to bear the weight of Billy and the bicycle, and to keep them out of the water. So that Billy found himself riding splendidly over the waves, and there was no more splashing than there would have been on the road on a very muddy day. Luckily, the sea was smooth, or I don't know what would have happened. It was smooth and greeny-blue, and the sun made diamond sparkles on it, and Billy felt as grand as grand to be riding over such a glorious floor. It was a fine time, but rather an anxious one too. Because, suppose the string had not held? No one could possibly ride a bicycle on the sea unless they had the really only truly right sort of kite to hold the machine up.
Away and away went the kite, through the blue air up above, and away and away went the bicycle over the greeny, foamy sea down below, and away and away went Billy, and the kite went faster and faster and faster, and faster went the bicycle—much, much faster than you would believe unless you had seen it as Billy did. And just at the front-door of the Bay of Biscay the bicycle caught up with a P. and O. steamer, and the kite followed the course of the ship, and went alongside of it, so you can guess how fast the bicycle was going.
And the Captain of the ship hailed Billy through a speaking-trumpet, and said:
'Ahoy, there!'
