The army officer made sure to secure his young passenger with a safety belt.  He might scorn such devices himself, but there was always more or less risk to an inexperienced air traveler, and he did not wish to take unnecessary chances.  This lad had folks at home to whom his life must be very precious.  He was only a boy, to be sure, but ere long he would reach man’s estate.  And in this country of ours, who can say what the future holds for any lad?  Years ago, who among his school companions on Mt.  Auburn, in Cincinnati, would have dreamed that in the course of time clumsy, good-natured Billy Taft would for a period of four years occupy the Presidential chair at Washington, and be looked upon as the foremost man in all the wide world?

Hugh and Ralph kept tabs of every little thing that was done.  They found themselves sharing Bud’s enthusiasm for the subject of aviation, and they, too, were promised a ride with the officer after his return.

At a given signal, the start was made.  The big monoplane rushed along the ground, wobbling somewhat because of inequalities in the surface of the field.  After it had gone a certain distance, it was seen to leave the earth gradually, as the pilot changed the conditions in respect to planes and rudder.

“Oh! see how she rises, for all the world like a graceful bird!” exclaimed Ralph.  “I’ve never been so close to an aeroplane before, and I tell you, Hugh, I can mighty easily see how it makes a fellow wild to embark in the business.”

“Well, there will be some years pass before anyone of us reaches an age to decide what our future may be,” Hugh replied; “and before that time comes, even Bud, crazy as he seems now to belong to the Flying Squadron, may change his mind a lot of times.  But one thing I do know, and that is, I’m glad we struck up an acquaintance with the Lieutenant; and ditto, that I’m going to have a spin with him in the air.”

They watched the monoplane mount fairly high and make several large curves.  Apparently the pilot did not think it best to try any difficult business while he had a novice along with him, because there was no telling how Bud might act.  After being up some twenty minutes, the monoplane was once more directed toward the field.

“Oh! see what he is doing now!” exclaimed Ralph, clutching the sleeve of his companion’s coat in his excitement.  “He’s headed the nose of the air craft downward, and seems to be just whooping it up for solid ground!  I hope nothing has happened, or that they’ll strike hard, for poor Bud will be smashed, that’s what!”

Hugh laughed, for he was much better informed on all aviation topics than the other scout.

“Oh! that’s what they call volplaning,” he hastened to say, while he watched the coming of the air craft with eagerness.  “The motor is shut off, and deflecting the rudder to a certain angle, a glide is made toward the earth.  When they get to a certain distance, you’ll see a sudden change take place.  There, what did I tell you, Ralph?”
