Removing Calcium Deposits on Glass
A good way to clean glass vessels in which hard water is boiled is to use the following mixture to remove not only the calcium deposits, but also rust or sulphur stains that may be present. The solution is a mixture of ammonia water and a few ounces of salt. This should be placed in the glass vessel and boiled until the deposits disappear. The ammonia water may be made of any strength by diluting if necessary.
A Cold-Chisel Guide
When making long cuts with a cold chisel, it is almost impossible to guide the chisel edge along a line made with a scriber or pencil and have a straight cut. I find that it is much easier to use a guide, as shown in the sketch. The guide is made of a piece of wood, about 1 ft. long and 1-1/2 in. wide. A slot is cut in the center, wide enough to receive the chisel edge snugly, and about 9 in. long. The guide is clamped to the work, and the cold chisel slipped along in the slot as it is successively hit with a hammer.—Contributed by G. H. Holter, Jasper, Minn.

Care of Paintbrushes
When laying aside paintbrushes, the usual custom is to place them in water and then forget all about them until needed again, with the result that the water usually is found more or less evaporated and the brushes hardened. If a quantity of oil, A, is poured on the water B, it will prevent this evaporation and keep the brushes in good shape.
