fountain or reservoir inside of the stamp and a simple pressure of the hand is all that is required to give a perfect impression on any surface. The saving of time as well as the greater accuracy of printing by such a process is evident as also its superior neatness in printing and clearness for when not in use it may be carried in the pocket without danger of soiling the clothes. One charge of the ink is sufficient for thous ands of impressions ; and it is not affected by climate or time—it will be as good when five years old as when new and it can be prepared of any desired color. This device may be used with the greatest rapidity ; impressions being obtained from it at the rate of one hundred per minute with a guarantee of correctness which for Post-Office use is a desideratum long sought for. Stamps are imperfectly cancelled by the old method and this is taken advantage of by many rogues who recover the partly defaced stamps for a second usage. It is claimed that this cannot occur with this stamp as the ink-mark is ineradicable. The mechanical construction is simple. The ink A is con tained in the tube B and is of a semi-solid or pulpy nature ; the piston C rests on this ink and pressure is communicated to it through the rod D and knob E; the piston rod is larger in one part and the shoulder of the larger portion rests against a shoulder inside the body of the handle so that it only rises to a certain hight. As pressure is communicated to the knob by the hand the ink is forced down through the slits of the comes reduced in quantity the lower half; F of the tube B is screwed up on the upper part so that the ink is entirely consumed before renewal is necessary. Some of these stamps are made without the knob at the top the simple action of impressing the stamp on paper be ing all that is required to force the ink out. New charges of ink may be inserted by simply unscrewing the bottom half of the tube B ; the connection of these two parts not being easy to show cl
