"I've noticed that too," replied Roy, "but never thought it worth while to take the trouble to ride any differently. What's the odds so long as one has the whole road to wobble in?"

"None whatever," said the stranger, with a laugh, "only experts who come on your track will think you are not at all careful as to your style, or else they will put you down as new hands at the business. But suppose you should come to a railroad bridge with only a single plank laid down for one to walk upon. If you tried to run over it you would go off sure; and it would be a job to dismount and carry your wheels. Besides, when you got home you wouldn't like to confess that you had done such a thing."

"But you see we haven't found any bridges of that sort in our way yet, and we don't mean to," replied Joe. "Our plan is to follow the road and keep clear of the tracks."

"That's the resolve I made when I set out, but I haven't held to it. I am pretty well satisfied now that you are not very far from home."

"What makes you think so?"

"Because you don't seem to care anything for distance; but wait until you have been in the saddle a week at a stretch, and you will be glad to cut off all the miles you can. You will find that the railroad generally follows the shortest route between two points, and if you have made up your minds to stop for the night at a certain place, you will want to get there the easiest way you can. That's the time you will probably take to the track and find some of the bridges I spoke of a minute ago."

The boys traveled several miles in company with the pleasant stranger who, to quote once more from Roy Sheldon, "was just chuck full of good stories and advice," and it was with much regret that they took leave of him, saw him turn off from their route and continue his journey alone. How often it happens that little things bring about great events! You shall presently see what grew out of this short interview which happened by the merest accident.

"From this day forward I mend my style of riding," said Joe Wayring, when their chance companion had been left out of sight. "I never knew before that a wheelman left traces by which an expert could judge of his skill, but I know it now, and by this time next week I bet you I'll be steady enough to ride a six-inch plank on top of the highest railroad bridge in the country."

The others said the same, and from that moment began exercising more care in the management of their wheels. If that stranger could have come up behind them now, he would not have seen so many zig-zag tracks in the road. But no doubt he would have laughed at them for so quickly forgetting their resolve to "stick to the highway and steer clear of the railroad tracks"; for that was just what they did. Before a week had passed over their heads they began to realize that it required a good many motions with the pedals to take them a day's journey, and bring them to the place at which they had beforehand decided to pass the night, that there was a good deal of sameness in wheeling, in spite of the new scenes and new faces that were constantly coming before them, and they were not so very long in learning by actual test that "the railroad usually follows the shortest route between two points." But, strange to say, they encountered but few cattle-guards, no bridges or trestle-works, and the culverts were so well covered that they scarcely knew when they passed over them. Except when following these short cuts they adhered rigidly to the instructions laid down in their road-book, but one day even that guide, which ought to have been infallible, led them astray; and here is the passage that did the mischief:
