Now for the lamp, and your lantern will be finished. You had better make this, as it would cost you 10s. 6d. to buy, and you have nearly all the materials required. Cut a piece of stout tin nine inches and three quarters long and three inches and three quarters broad; make it into a tube by joining the short edges together, lapping them a little, about an eighth of an inch, and soldering the joint. For the bottom cut a piece of tin round, the exact size to fit tightly into the tube; in the middle of this cut a circular hole three-quarters of an inch in diameter, solder this in the lamp so that it is half an inch from the bottom end, and then cut the half-inch that projects like you did the top of the chimney. Now make a tube of tin to fit the hole in the bottom, and long enough to come level with the top of the lamp; solder this up, and into its place in the lamp ([Fig. 15]). Next you must get a short piece of brass curtain-rod that will just fit tightly over this last tube and be the same length. In this brass tube you must cut a spiral slot, running from top to bottom, and going once round. The slot is to be cut quite through the brass ([Fig. 16]). The best way to do this is to cut a piece of wood, about eight inches long, and thick enough to fit very tightly in the brass tube; then with a sharp file make your cut. The cut is to be about one-sixteenth of an inch wide. Now push this brass tube on to the tube in the lamp, and fix it by pressing the brass in a little.
The next thing to make is the wick-carrier. Make a short tube of tin three-fourteenths of an inch long, and to fit easily over the brass tube; round the bottom of this short tube put a band of stout tin one-fourth of an inch wide; through this band drill a hole one-sixteenth of an inch, and solder a sixteenth-of-an-inch wire through it, so that it projects one-eighth of an inch inwards, and one-eighth of an inch outwards. This little wick-carrier must be notched with a penknife ([Fig. 17]), so that it is covered with little points directed downwards; these points are to catch in the wick and hold it firmly.
