(From the Inland Printer.)

Glycerine as a Dryer.—It may not be generally known that ink will dry very quickly on paper damped with glycerine water. Posters with large and full-faced types will dry in a quarter of an hour, while the drying process, when the printing has been done on paper simply wetted in the ordinary way, will require hours.

Stereotypers' Paste is composed of the following ingredients: Water, flour, starch, gum arabic, alum, and whiting. The best flour and starch are to be used. These foregoing articles, excepting the whiting, are thoroughly mixed, and heated by steam. When the mass is thoroughly homogeneous, sufficient whiting is added to give it stiffness.

Frost-proof Ink.—Aniline black one dram, rub with a mixture of concentrated hydrochloric acid one dram, pure alcohol ten ounces. The deep blue solution obtained is diluted with a hot solution of concentrated glycerine one-and-a-half drams, in four ounces of water. This ink does not injure steel pens, is unaffected by concentrated mineral acids or strong alkalies, and will not freeze at a temperature of 22 or 24 degrees below zero.

Printing on Leather.—A correspondent writes: I want to print or stamp in black upon passbook skiver (uncolored sheep's leather, such as is used to cover passbooks and law books). What can I use that will dry quickly? On former occasions I used regular printers' ink, mixed with a little quick-drying varnish, but it took over a week to dry. Answer.—loz. beeswax, ¼oz. gum arabic, dissolved in sufficient acetic acid to make a thin mucilage; ¼oz. Brown's japan, ½oz. asphaltum varnish. Incorporate with lib wood-cut ink.

Type-Writer Ink.—The ink that is used in inking the indelible ribbon in type-writers, which writes black, but copies a very dark blue, is made as follows: Take vaseline of high boiling point, melt it on a water bath or slow fire, and incorporate by constant stirring as much Prussian blue as it will take up without becoming granular. Remove the mixture from the fire, and, while it is cooling, mix equal parts of petroleum, benzine, and rectified oil of turpentine, in which dissolve the fatty ink, introduced in small quantities, by constant agitation. The volatile solvents should be in such quantity that the fluid ink is of the consistency of fresh oil paint. One secret of success lies in the proper application of the ink to the ribbon. Wind the ribbon on a piece of cardboard, spread on a table several layers of newspapers, then unwind the ribbon in such lengths as may be most convenient, and lay it flat on the paper. Apply the ink, after agitation, by means of a soft brush, and rub it well into the interstices of the ribbon with a stiff toothbrush. Hardly any ink should remain visible on the surface.
