When one fits up an attic or a back room as a workshop, it is seldom that A gas connection is available on about the same level as the workbench so that a Bunsen burner and soldering apparatus may be operated. To install the standard gas pipe, it would be necessary either to alter the chandelier connection or to tear up some of the plaster, the former plan resulting in a rather conspicuous display of pipe and the latter in considerable expense. The following method permits the rolling of a pipe, about the size of a lead pencil, from paper that becomes so stiff that it is almost impossible to crush it between the thumb and fingers. This small inconspicuous pipe may be Run directly from the side of the valve on the chandelier to the wall, as shown in the sketch, thence down some corner formed By A Door Jamb Or window frame, which protects it and renders it almost unnoticeable.
Ill: The Tube is Run Out Horizontally from the Chandelier to the Wall Where the Drop is Connected

A good grade of tough Manila paper should be procured and cut into strips, about 18 in. long and wide enough to build up a tube at least 1/32 in. in diameter. This will require from 4 to 6 in., according to the thickness of the paper. A piece of 1/4. round iron or hard wood, 20 in. long, is procured and carefully oiled or greased. Apply a coat of strong fish glue to one of these pieces of paper, omitting a strip along one edge, about 1 in. wide. Using the outspread fingers of each hand, begin with the unglued edge and roll the paper around the wood. As it is impossible to get the paper uniformly tight with the fingers, select A smooth place on the table and then roll the newly formed tube forward by means of a piece of board, as shown in the illustration. On the return stroke lift the board. In this way it is possible to get a tight, smooth tube. Immediately withdraw the core, twisting it slightly in a reverse direction if it tends to stick. Before using the core again, make sure it is free from glue and regrease it. When a sufficient number of tubes have been made and hardened, neatly trim the ends off squarely, and then form an equal number of short tubes, about 2 in. long, by winding a strip of glued paper on a large wire nail until a diameter is reached that will fit snugly into the pipes already made. The joints may then be set up with strong glue and finally wrapped with two thicknesses of paper on the outside. The construction of these joints is shown in the cross section.
The connection with the chandelier can be made by means of A metal tube soldered in at A point where the regular valve will cut off all connection with the paper piping when it is Not in use. This metal tube should be coated with thick shellac, and the paper tube slipped over it for 1 in. or more, after which the joint should be given several additional coats on the outside. A small regulating gas cock can be attached to the lower end of the piping, and if this is rigidly fastened to the wall, or casing, the connecting and disconnecting of the rubber tubing will not disturb the piping in any way. - Contributed by John D.
