DEAR ST. NICHOLAS: I have taken ST. NICHOLAS for several years, and like it better every year. I often read over the old numbers, and find many things that seem almost new to me. One of these was "John Spooner's Human Menagerie," in the number for April, 1875, and I have been trying to get up a "menagerie" like John's. I can make most of the wonderful living curiosities, but I do not know how to make a curtain that will "go up with a flourish." I have made one to draw sideways, but I want one to go up. Please inform me how to construct it.--Yours truly, FRED R. MARTIN. Here is a tolerably easy way to make a stage-curtain that will "go up with a flourish," and come down either quickly or slowly, as may be wished. It is easily kept in order, and readily repaired when damaged. Above the stage, at the front, set up a stout cross-beam. Let the curtain be of some opaque stuff that will fold well. Fasten its upper edge firmly to the front of the cross-beam. Weight the lower edge of the curtain with a long roller some inches wider than the curtain. Sew to the curtain, on its wrong side, perpendicular rows of rings set at suitable distances apart, and in level lines across. The more rows, the more evenly will the curtain fold. Tie a strong thin cord about the roller in a line with each perpendicular row of rings, and pass each cord through its proper rings. On the bottom of the cross-beam above the several rows of rings, fasten large smooth rings to be used instead of pullies. Pass the cords up through the large rings, and gather them at one end of the beam. Then fasten the ends of the cords to a rope, taking care while doing this that the curtain is down, and hanging properly, and that all the cords are drawn equally tense. There should be a stout pin or hook at the side of the curtain, to which the rope is to be fastened when the curtain is drawn up. Take notice that the cords are of different lengths and must be free from knots. The curtain should not touch the stage, and may be kept in place by fixing the ends of the roller in iron rings or between pegs. * * * * * TWO WAYS OF CARRYING THE MAIL.
