head on a table, and set a hot smoothing-iron on the woven lock--an awkward but efficient process. It is not good to put the hair up on metal pins or hair-pins overnight for two reasons: the perspiration of the head will rust the pins, insensibly, so that they will cut the hair; and the contact of iron with the sulphurous gas given out by hair during sleep tends to darken and render the color displeasing. Rubber crimping-pins, fastened by a rubber catch, are a late invention, and a great improvement. But a loop of thick elastic cord is better than any thing. The hair is woven in and out as on a hair-pin, the elastic holds it when the fingers are withdrawn, and it is pleasanter to sleep in than half a dozen stiff pins. I know more than one piquant little lady whose “naturally” waving tresses are the admiration of her friends by this simple means; and as the process has gone on for years without lessening the flow of ruffled hair, it must be conceded that crimping does not always hurt it. Iron hair-pins hurt the head more than a generation of friseurs. The latest accusation against them is that they draw off the healthy electricity of the head; and to a generation which complains of paralysis from using steel pens, and uses patent glass insulators for the legs of its bedsteads, this will seem no frivolous charge. The patent insulators are a fact. Their use is advised by medical men for all neuralgic, rheumatic, and sleepless people, and one of the largest glass firms in New York makes their manufacture a specialty. The patent and perfect hair-pin is not yet invented. Rubber pins are clumsy if harmless, but there are gilt hair-pins made of a yellow composition metal which are pleasanter to use than common ones, and very becoming in blonde hair. Dark-haired people must stick to the rubber pins, or at least see that their black ones are well japanned, so as not to cut their locks.
