When these dispositions were in a fair way towards completion, Herbert went in search of his commanding officer to report progress. How very right of him! What were you reading? Horatia. My Uncle in the Scilly Isles, whose mind.... 大发快三有神器吗 How very right of him! What were you reading? A year or more later, when the Lincoln family had crossed the river to Indiana, there was added to the "library" a copy of the revised Statutes of the State. The Weems's Washington had been borrowed by Lincoln from a neighbouring farmer. The boy kept it at night under his pillow, and on the occasion of a storm, the water blew in through the chinks of the logs that formed the wall of the cabin, drenching the pillow and the head of the boy (a small matter in itself) and wetting and almost spoiling the book. This was a grave misfortune. Lincoln took his damaged volume to the owner and asked how he could make payment for the loss. It was arranged that the boy should put in three days' work shucking corn on the farm. "Will that work pay for the book or only for the damage?" asked the boy. It was agreed that the labour of three days should be considered sufficient for the purchase of the book. The seventeenth century was not to end, however, without practical experiment of a noteworthy kind in gliding flight. Among the recruits to the ranks of pioneers was a certain Besnier, a locksmith of Sabl茅, who somewhere between 1675 and 1680 constructed a glider of which a crude picture has come down to modern times. The apparatus, as will be seen, consisted of two rods with hinged flaps, and the original designer of the picture seems to have had but a small space in which to draw, since obviously the flaps must have been much larger than those shown. Besnier placed the rods on his shoulders, and worked the flaps by cords attached to his hands and feet鈥攖he flaps opened as they fell, and closed as they rose, so the device as a whole must be regarded as a sort of flapping glider. Having by experiment proved his apparatus successful,35 Besnier promptly sold it to a travelling showman of the period, and forthwith set about constructing a second set, with which he made gliding flights of considerable height and distance. Like Lilienthal, Besnier projected himself into space from some height, and then, according to the contemporary records, he was able to cross a river of considerable size before coming to earth. It does not appear that he had any imitators, or that any advantage whatever was taken of his experiments; the age was one in which he would be regarded rather as a freak exhibitor than as a serious student, and possibly, considering his origin and the sale of his first apparatus to such a client, he regarded the matter himself as more in the nature of an amusement than as a discovery. Oh, she merely cried and whimpered, and hid her face in her apron. She is terribly weak-minded, poor creature. In Manly鈥檚 engine the cylinders were of steel, machined outside and inside to 1/16 of an inch thickness; on the side of the cylinder, at the top end, the valve chamber was brazed, being machined from a solid forging. The casing which formed the water-jacket was of sheet steel, 1/50 of an inch in thickness, and this also was brazed on the cylinder and to the valve chamber. Automatic inlet valves were fitted, and the exhaust valves were operated by a cam which had two points, 180 degrees apart; the cam was rotated in the opposite direction to the engine at one-quarter engine speed.419 Ignition was obtained by using a one-spark coil and vibrator for all cylinders, with a distributor to select the right cylinder for each spark鈥攖his was before the days of the high-tension magneto and the almost perfect ignition systems that makers now employ. The scheme of ignition for this engine was originated by Manly himself, and he also designed the sparking plugs fitted in the tops of the cylinders. Through fear of trouble resulting if the steel pistons worked on the steel cylinders, cast-iron liners were introduced in the latter, 1/16 of an inch thick. An engine of the rotary type, almost as well known as the Gnome, is the Clerget, in which both cylinders and crank case are made of steel, the former having the usual radial fins for cooling. In this type the inlet and exhaust valves are both located in the cylinder head, and mechanically operated by push-rods and rockers. Pipes are carried from the crank case to the inlet valve casings to convey the mixture to the cylinders, a carburettor of the central needle type being used. The carburetted mixture is taken into the crank case chamber in a manner similar to that of the Gnome engine. Pistons of aluminium alloy, with three cast-iron rings, are fitted, the top ring being of the obturator type. The large end of one of the nine connecting rods embraces the crank pin and the pressure is taken on two ball-bearings housed in the end of the rod. This carries eight pins,435 to which the other rods are attached, and the main rod being rigid between the crank pin and piston pin determines the position of the pistons. Hollow connecting-rods are used, and the lubricating oil for the piston pins passes from the crankshaft through the centres of the rods. Inlet and exhaust valves can be set quite independently of one another鈥攁 useful point, since the correct timing of the opening of these valves is of importance. The inlet valve opens 4 degrees from top centre and closes after the bottom dead centre of the piston; the exhaust valve opens 68 degrees before the bottom centre and closes 4 degrees after the top dead centre of the piston. The magnetos are set to give the spark in the cylinder at 25 degrees before the end of the compression stroke鈥攖wo high-tension magnetos are used; if desired, the second one can be436 adjusted to give a later spark for assisting the starting of the engine. The lubricating oil pump is of the valveless two-plunger type, so geared that it runs at seven revolutions to 100 revolutions of the engine; by counting the pulsations the speed of the engine can be quickly calculated by multiplying the pulsations by 100 and dividing by seven. In the 115 horse-power nine-cylinder Clerget the cylinders are 4鈥? bore with a 6鈥? inches stroke, and the rated power of the engine is obtained at 1,200 revolutions per minute. The petrol consumption is 0鈥?5 pint per horse-power per hour. Col. Good-morrow, Weasel. An old campaigner, you see, learns to be an early riser. 鈥業 have just come in from paying a round of visits, with a card of admission in my hand.... My hand trembles with the heat, for it is warm walking at this hour, and I always walk fast when I walk in the streets alone. I look forward with much pleasure to the evening鈥檚 entertainment. I only wish that you and dear Bella could enjoy it too; but I hope that your dinner in September may afford you as much gratification as this would have done....
