eing turned, caused the platen to descend,and the impression was made. The screwwas then raised, the form slid back, the frameraised, and the paper lifted and examined bythe pressman to see if his impression wasgood. If it satisfied him, he proceededto ink his types for a new impression. Theink employed in printing is very differentfrom that employed for writing, and muchskill is required in the manufacture. Itmust be soft, adhesive, and easily trans-ferred ; it must dry quickly, and be durable,and not liable to spread. The usual mate-rials are linseed oil, rosin, and coloring mat-ters, lamp-black being used for black ink.The peculiar mode of the best makers issomewhat of a secret.

There was lit-tle room for much expansion, under such astate of printing. The first great advance inthe direction of speed, was when the leverwas substituted for the screw in making theimpression. This was introduced by Mr. JohnClymer, and called the Columbian, or Clymerpress, in which there was no screw, but thehead itself was a large and powerful lever,acted on by proportionate levers, thus bring-ing to perfection, for presses of a large size,certain principles of leverage which had pre-viously been patented in England, and usedin presses of a small size,
