For making the bag tight a paste composed of resin, beeswax and sweet oil boiled together is here recommended. This, when cool, should be slightly thicker than cream. After the stocks have been inserted a few spoonfuls of this paste should be put in (lukewarm), then the stocks stopped up and a little wind left in the bag to prevent its sides sticking. The skin should be rubbed and wrought until it becomes impregnated with the paste. When pipes are much used, and the bag draws a good deal of water, the reeds will always be damp. To remedy this, a little salt may be put into the bag, which will cause the damp to be discharged through the skin. This, however, might make an old bag give way altogether. Water should never on any account be put into the bag. The bag should always be soft and pliable. This can be managed in several ways. After being dried, say half a teacupful of melted brown sugar may be passed into it, and worked with the hands, the skin being then hung up overnight for the surplus sugar to run out. VII.—KEEPING THE PIPES IN ORDER. Pipes as a rule should be cleaned thoroughly at least once a month, and if much played on once a week. Cocoa-nut oil will be found to serve the purpose best. When the pipes are to be cleaned the reeds should first be removed, and either placed in a bottle or rolled in a damp rag. The different joints should then be detached and the pieces cleaned outside and inside with an oily rag, a long feather saturated with oil being passed through the joints. If not required immediately, and after the reeds have been reinserted, the instrument should then be laid past in its oily state for a few hours. Before being used, the reeds should be again abstracted and all the parts carefully cleaned. Care must be taken that the warping on the joints is never allowed to get ragged or soaked with water, as this will cause the joints to crack, or swell the hemp, and render them difficult to move. The player cannot be too particular in satisfying himself that none of the joints are too tight. New pipes, especially in hot weather or warm climates, should before being used be laid up for a few days in cocoanut oil and exposed daily to the sun; care, however, being taken that they are not allowed to dry and that they are frequently turned and well wetted with oil. This will season the wood, and lessen the danger of splitting. * * * * *
