The coils must lie exactly under one another. Make plain scratches at each end of the paper with a sharp steel point. Cut off at a distance of 1/16-inch from the lines, and work up to the lines with a file, finishing by rubbing the ends on a piece of emery cloth resting on a hard, true surface.

K is in each case a small wooden knob on a piece of 3/16-inch brass rod; O a 1-1/2-inch brass screw; A a piece of sheet brass 3-1/2 inches long, marked off carefully, drilled 1/8 inch from the centre of each end for the pivot screws, and in four places for the holding-down screws, and bent up at the ends to form two standards.

This year saw also the completion of the latest type of naval 16-inch gun, throwing a projectile weighing 2,100 pounds. Our newest battleships will mount them.

Jack forgot all about reporting to Captain Raleigh for further orders, and as the battle raged, he continued to fire one of the big 16-inch guns he and other unwounded British tars. Frank had not seen his chum for an hour; and chancing to poke his head into the forward turret, he was surprised to see Jack working like a Trojan with the members of the gun crew. "Good work, Jack!

Her steaming radius is about 50,000 miles, depending upon the speed. She carries twelve 16-inch guns, twenty-two 6-inch guns, sixteen 4-inch anti-aircraft guns, eight 3-pounders, four rapid-fire guns, six aerial torpedo tubes, and six bomb droppers, which can simultaneously discharge tons of explosives. She has a complement of 1400 officers and men.

The hole for the pivot 5/16-inch steel bar should be long enough to admit a piece of tubing fitting the bar, to diminish friction, and an important point, be drilled near the handle edge of the lever, so as to leave plenty of wood to take the strain. The last remark also applies to the hole for the balance pin at Q.

The centre of each should be marked, and four lines 45 degrees apart be scratched through it from side to side. A circle of 15/16-inch radius is now drawn to cut the lines, and punch marks are made at the eight points of intersection. Solder the covers lightly to the foot side of their standards, marked sides outwards, and drill 1/8-inch holes through cover and standard at the punch marks.

If guns decide everything, then let them be trained on other guns. Let the gun that drives farthest and goes surest win. If every siege is decided by the German 16-inch howitzers, then let us put up brick and mortar or steel against them, but not men. The day for the bleeding human body seems to be over now that men are mown down by shells fired eight miles away.

It resulted in part, if not wholly, from the visual enlargement by irradiation of the bright disc of the moon. Professor Comstock, employing the 16-inch Clark equatoreal of the Washburn Observatory, found in 1897 the refractive displacements of occulted stars so trifling as to preclude the existence of a permanent lunar atmosphere of much more than 1/5000 the density of the terrestrial envelope.

It is a consequence of the reliance of modern armies on the mechanical force of artillery to which the Germans were especially addicted; for while 16-inch howitzers could pulverise any position, they could not pursue with the speed required to encircle and capture armies in the field.
