_The Fox Breech Loading Shot Gun.—(Made by American Arms Co., Boston, Mass.)_—To take apart: To detach the barrels, first open the gun as if for loading, which is done by pressing forward the thumb-piece on the top of the stock; then with the left thumb at a point about two inches from the end of the barrels, press the barrels towards the right and the gun is in position to load. Next turn the gun over in the right hand, holding it by the small of the stock, the end of the stock under the elbow supporting the weight of the gun; with the left thumb press the extractor home, and, with the thumb placed on the extractor spring, as close up to the fore end as convenient, press down the extractor firmly, and gently swinging the stock to the right until the detachment is obtained. To attach the barrels again, grasp the barrels with the plate up, so that the large screw at the head of the plate comes about at the center of the hand; be sure that the extractor is home. Place the opening for the screw which is in the breech-plate, over the screw, with the stock at an angle of about forty-five degrees with the barrels, at the same time put the left thumb on the end of the fore end, holding it firmly and flat on the plate, the stock-plate covering the guide-pin next the screw on the barrels, but not the pin on the extractor; gently move the stock until the two plates come into perfect contact, when the barrel will swing into position. To remove the extractor, detach the barrels from the stock, lay them on a table with the plate up and muzzle from gun; pull out the extractor as far as it will come readily, then turn it to the _left_ until the short arm strikes end of the barrels; now draw it straight out, meanwhile holding a finger over the extractor button to prevent its springing out and getting lost, when the button and locking stud will fall out of their own weight. To replace the extractor, lay the extractor button in its cavity and slide the long shank of the extractor through it, then place the locking stud in position, holding it snug against the rear end of its seat, run the extractor into it, solid home, and turn to the _right_ till the short arm is opposite its hole, when push straight in. To take out firing pins, remove the screw holding them, which will be found in the breech-piece at the rear of the scroll-fence. _The Lefever Hammerless Gun.—(Made by Daniel Lefever, Syracuse, N. Y.)_—Locks are rebounding. To take apart: To take off the lock, see that both hammers are down; take out lever-screw; remove lever; turn out lock plate screw and drive off right hand lock by tapping on head of lock plate screw; take out the screw and insert in sear hole, and drive off left hand plate.
