Many attempts to produce a shingle machine that -will make shingles with a smooth surface like shaved shingles, and do the same rapidly and economically, have been made, and some partial successes have been achieved in this line. The machine herewith illustrated makes a compromise between sawed and shaved shingles by planing the side designed to be laid uppermost, and as the weather side of shingles is the only one which is required to be smooth, if the other is flat, this compromise will probably provo acceptable to the trade, provided the shingles are in other respects all that could be desired. vVe have seen a sample of the shingles, and will say that we think them a very superior article, although we cannot vouch that all shingles matJa *y the machine would correspond with the samp] e shown to us. We see no reason, however, to suppose that they would not, provided the timber from which they are ?raade is of the proper quality. The engraving shows the machine in perspective, and we shall content ourselves with such a general description as will exhibit the principle upon which the machine operates. The cuttftg is done by a circular saw, A, and plane knives set in tin; planer head, B. The machine receives motion throu gh ' the main driving pulley, E, and motion is transmitted to the planer shaft by a belt running on the pulleys, C and D. A pinion on the end of the planer shaft imparts motion to the gear, F, which, througl a pinion fixed to the opposite end of its shaft, revolves the gear, G, fixed to the shaft of the bolt carrier, bringing the bolts successively over the planer and saw as required. The bolts are held by spurred rollers, H, which are driven by a ratchet and pawl movement, actuated by a vibratory lever, -which alternately feeds forward the top and bottom rollcrs,sothat the proper wedge shape of the shingle is obtained. The feed rollers are placed at the ends of clamping arms, I. The upper pair of each set of clamping arms is held by a lever cam which locks the apparatus, and holds the bolt firmly to the work. By these devices the surface of the bolt is first planed, and then being brought to the saw a shingle is cut off. We are informed the machine operates with great rapidity and with but little moro consumption of power than the saw would alone require. Patented April 13, 1869, by Merrill Chase, Jr., and Horace J. Morton, of South Paris, Me., assignors to themselves and Freeman C. Merrill of the same place, where the machines may be seen in operation, and the working of which is said to be very satisfactory. For further particulars address Merrill & Morton, at the above-named place. The London Star furnishes an interesting account of some of the dangers that must attend all attempts to navigate the air. A Mr. Youens recently undertook an ascent near Hud-dersficld, in the Aerial, which is capable of holding 20,000 cubic feet of gas. It rises to a hight of fifty feet, and expands to one hundred feet in circumference. Away floated the balloon in a westerly direction, oscillating for a considerable distance in a most extraordinary and unusual manner. M. Youens experienced a stronger breeze than he had anticipated, and, the current changing rapidly, his energy and knowledge as an aeronaut were very closely taxed in the management of the balloon. A fresh current drove the Aerial to the east for a time, but presently another gust, unexpectedly, in the direction of Halifax, thence towards Bradford, in a northerly course, and after the lapse of twenty minutes, the Aerial and its occupant pierced the clouds. Mr. Youens then began to make observations for the purpose of selecting a suitable site on which to descend, and in a few minutes concentrated his attention upon a field in which a fete was being held. The breeze, however, carried the Aerial some three miles further, and a second time Mr. Youens attempted to lower himself in a field adjoining some farm houses at Denholme. Cautiously opening the. escape valve, Mr. Youens continued the journey downwards and threw out the grapnels. Impetuous blasts of wind increased the diffi culty of bringing the Aerial to anchor. A strong wind prevailing, the balloon became unmanageable, and drifted over fields and stone walls with amazing velocity. The flukes of the grapnels penetrated the ground and uprooted the earth as they followed in the wake of the balloon, while the aerial chariot dashed onwards, making, in its career, wide gaps in several stone walls. Mr. Youens, preparing to encounter the worst fate, wrapped the end of the cord which opens the escape valve round one of his wrists, and burying himself in the car, permitted the balloon to proceed until the breeze subsided ; when, after the car had been thrice capsized, and every article which it contained thrown out, Mr. Youens, who received no injuries, anchored, and completed a voyage of many miles, occupying half an hour in its accomplishment.
