RECENT Shading Pen. We give an engraving of a novel marking pen, called bythe inventor the chromatic, from the fact of its usingtwo kinds of ink at once, the pen being provided with alongitudinal partition to prevent the mixing of the twoink*. Each part of the pen is also made to put each kindof ink on the paper in delicately shaded lines, so that with. one stroke lettering may be made of two different colorsthat would be impossible with the old pen or a brush. Thepen is especially adapted to lettering all kinds of showcards, notices, bulletins, signs, for making headings, is also excellent for writing mottoes, texts, etc. Thisinvention was recently patented by Mr. J. W. Stoakes, ofMilan, O. ^Vagon Hub. An improved hub for wagon or carriage wheels, shown inthe annexed engraving, has been patented by Mr. John , of Vermilionville, La. A tapering axle box. A,provided at its inner end with enlargements for the collaron the axle, is screwed into a tubular core of the hub. Itis provided at or near its middle with a ring of mortises,the separating partitions of which project above the surfaceof the core, so that the depth of the mortises will be greaterthan the thick-ness.
