32. It should be well rubbed over with oil, and a little bees-wax should be applied between it and the barrel.

33. A mixture composed in the proportion of 2 lbs. bees-wax, half a pint turpentine, and 2 oz. resin, if rubbed over the stock, will give it a nice polished appearance. 34. Yes; nearly always some, and very often a good deal.

FOURTH LESSON.

1. It contains instructions for remounting the lock.
2. The swivel is attached to the tumbler.

3. The tumbler is placed in the axle-hole of the lockplate, with its bearer against the hind-stud.

4. The bridle is fixed on the pivot of the tumbler, with its stud in the lock-plate, and the bridle-pin screwed home. 5. The bridle-pin is flat at the end, and the other pins are rounded off.

6. The sear; which is placed between the bridle and the lock-plate, with its nose against the tumbler, and the sear-pin screwed home.

7. The sear-spring; this is partly screwed to the lockplate, then with the thumb of the left-hand the spring is pressed until the stud enters the stud-hole, after which the sear-spring pin is screwed home.

8. The hammer; which is fixed on the squares of the tumbler in a position as if on the nipple, and the tumblerpin screwed home.

9. The mainspring, which is mounted thus; attach its claws to the pivots of the swivel, and place the stud in the lock-plate, and its catch against the fore-stud, after which, place the lock at full-cock to remove the cramp; this being done, ease the lock to half-cock.

FIFTH LESSON.

1. The uses of some of the parts of the lock are explained in this lesson, and those of the remainder in the following one.

2. Mainspring, sear-spring, and sear.

3. It is to draw the hammer down upon the nipple, which it does by acting upon the tumbler.

4. The stud on the return keeps the spring in its place, and the fore-stud secures the catch to the lockplate; this offers such a resistance that the action of the spring is ensured.

5. The toe of the spring bears against the body of the sear, and presses it outward whenever the tumbler is revolved, thus causing the nose of the sear to enter the bents.

6. The stud on the return keeps the sear-spring in its place, and, together with the sear-spring pin, secures it to the lock-plate, and offers such a resistance as ensures the action of the spring.

7. A stop on the movement of the tumbler, into the half and full bents of which the sear-nose enters, to keep the lock at half and full cock.

8. It should be made to fit the bents exactly.

9. On the arm.

10. The blade.

SIXTH LESSON.

1. Bridle, hammer, tumbler, and lock-plate.

2. It secures the tumbler and sear in their proper places on the lock-plate.

B

3. By means of the bridle-stud together with the sear

and bridle pins.

4. To explode the cap.

5. The tumbler.

6. To hold the hammer.

7. In order to sustain the force of the mainspring.

8. Two; called the half-bent and full-bent.

9. They retain the hammer in a position to enable the cap being placed on the nipple, and also to explode it.

10. The half-bent has two angles-the one acute, and the other obtuse, and the full-bent one.

11. In order to prevent the possibility of the sear-nose being released by the action of the trigger when the lock is at half-cock.

12. It should be so formed as to allow the sear-nose being withdrawn from it with the least possible resistance. 13. Yes.

14. Because otherwise the tumbler would not act properly. 15. An "arc of a circle" is a part of the circumference cut off by a straight line; things are in the same arc of a circle, when they are equidistant from the centre of the circle from which the arc has been cut off.

16. No; for then the position of half-cock would not be

secure.

17. It connects the mainspring with the tumbler by means of the swivel.

18. It is the foundation of the lock.

19. To secure the catch of the mainspring.

20. It acts as a break, and prevents the tumbler revolving beyond what is necessary when put in motion by the mainspring.

SEVENTH LESSON.

1. In this and the following lesson are explained the ways in which the rifle and ammunition may get out of order; also how this may be prevented.

2. That the several pins, pivots, &c., should be perpendicular to the lock-plate.

3. The force required to release the sear-nose from the full-bent when the lock is at full-cock.

4. No; on the contrary, it would tend to impair the lock.

5. Either by the full-bent and sear-nose not fitting each other properly, or by the sear-spring being too strong. 6. An alteration of the aim when firing.

7. The armorer.

8. When the parts are so embedded in the wood work of the stock, that they are prevented from exercising their proper functions.

9. The wood swelling in damp weather, or the lock being screwed too tightly to the stock.

10. No.

11. By being flat at the end.

12. Seven.

13. Four to the rifle, and three to the soldier.

14. The mainspring being too weak; the communication hole being too small; the nipple screw being too long; and the nipple being too large for the cap.

15 A dirty state of the tumbler axle hole and axle of tumbler; the cap not being pressed firmly home on the nipple; and the accumulation of dirt at the base of the touch-hole.

16. The hole by which the detonating spark is conveyed to the charge.

17. When screwed home, it would close up a part of the communication hole.

18. Dirt at the base of, or in, the touch-hole itself. 19. A negligent, careless, and inattentive, soldier.

EIGHTH LESSON.

1. A continuation of the seventh.

2. No; for these defects are very detrimental to accurate shooting.

3. Report the circumstance immediately.

4. Because doing so would bend the barrel.

5. By being placed forcibly in a rack, or by being piled carelessly, in consequence of which they often fall down.

6. The muzzle; for the barrel is thinnest here.

7. No; it cannot.

8. The fore-sight.

9. It will cause the rifle to carry high.

10. It will very probably cause the bullet to " strip" i. e., pass out of the grooving,-or else the wood plug may be driven through the bullet.

11. Unfit to be intrusted with a rifle.

12. The joint effects of moisture and air.

13. By keeping it perfectly dry, the muzzle-stopper in

the barrel, and the snap-cap on the nipple.

14. That he does not run the muzzle of his rifle into

the ground.

15. Ask permission to fall out to remove the dirt. 16. The bursting of the barrel.
