and nothing remained for him save to mount some eminence and, throwing himself forward into space and assuming the position of a flying bird, to commence flapping and beating the air with a reciprocal motion. First, he would buffet the air downwards with the left arm and right leg simultaneously, and while these recovered their position would strike with the right hand and left leg, and so on alternately. With this crude method the enterprising inventor succeeded in raising himself by short stages from one height to another, reaching thus the top of a house, whence he could pass over others, or cross a river or the like.
The perfecting of his system became then simply a question of practice and experience, and had young athletes only been trained from early years to the new art it seems reasonable to suppose that some crude approach to human flight would have been effected. Modifications and improvements in construction would soon have suggested themselves, as was the case with the bicycle, which in its latest developments can scarcely be recognised as springing from the primitive "bone-shaker" of thirty-three years ago. We would suggest the idea to the modern inventor. He will in these days, of course, find lighter materials to hand. Then he will adopt some link motion for the legs in place of leather thongs, and will hinge the paddle blades so that they open out with the forward stroke, but collapse with the return. Then look on another thirty-three years--a fresh generation--and our youth of both sexes may find a popular recreation in graceful aerial exercise. The pace is not likely to be excessive, and molestations from disguised policemen--not physically adapted, by the way, to rapid flight--need not be apprehended.
One of the best tests of Besnier's measure of success is supplied by the fact that he had pupils as well as imitators. First on this list must be mentioned a Mr. Baldwin, a name which, curiously enough, twice over in modern times comes into the records of bold aerial exploits. This individual, it appears, purchased a flying outfit of Besnier himself, and surpassed his master in achievement. A little later one Dante contrived some modification of the same apparatus, with which he pursued the new mode of progress till he met with a fractured thigh.
But whatever the imitators of Besnier may have accomplished, to the honest smith must be accorded the full credit of their success, and with his simple, but brilliant, record left at flood mark, the tide of progress ebbed back again, while mankind ruminated over the great problem in apparent inactivity. But not for long. The air-pump about this period was given to the world, and chemists were already busy investigating the nature of gases. Cavallo was experimenting on kindred lines, while in our own land the rival geniuses of Priestley and Cavendish were clearing the way to make with respect to the atmosphere the most important discovery yet dreamed of. In recording this dawn of a new era, however, we should certainly not forget how, across the Atlantic, had arisen a Rumford and a Franklin, whose labours were destined to throw an all-important sidelight on the pages of progress which we have now to chronicle.

CHAPTER II.
THE INVENTION OF THE BALLOON.
It was a November night of the year 1782, in the little town of Annonay, near Lyons. Two young men, Stephen and Joseph Montgolfier, the representatives of a firm of paper makers, were sitting together over their parlour fire. While watching the smoke curling up the chimney one propounded an idea by way of a sudden inspiration: "Why shouldn't smoke be made to raise bodies into the air?"
The world was waiting for this utterance, which, it would seem, was on the tip of the tongue with many others. Cavendish had already discovered what he designated "inflammable air," though no one had as yet given it its later title of hydrogen gas. Moreover, in treating of this gas--Dr. Black of Edinburgh, as much as fifteen years before the date we have now arrived at, had suggested that it should be made capable of raising a thin bladder in the air. With a shade more of good fortune, or maybe with a modicum more of leisure, the learned Doctor would have won the invention of the balloon for his own country. Cavallo came almost nearer, and actually putting the same idea into practice, had succeeded in the spring of 1782 in making soap bubbles blown with hydrogen gas float upwards. But he had accomplished no more when, as related, in the autumn of the same year the brothers Montgolfier conceived the notion of making bodies "levitate" by the simpler expedient of filling them with smoke.
This was the crude idea, the application of which in their hands was soon marked with
