A Typewriter That Adds and Subtracts Without a Mistake.

One of the 'new Model 11 Remington typewriters with the Wall adding and subtracting attachment has just been placed in The Republican office. This is a wonderful machine and will doubtless work a revolution in office business. The machine is used as a combined typewriter and adding machine. Each contributes to the work of the other and neither sacrifices anything to the other. The machine not only typewrites, but it adds and subtracts without an error, an automatic locking device preventing any errors in the tabulation of figures. If an incorrect total is written, the machine registers the mistake' and compels its correction. This combined typewriter, adding and subtracting machine sells for a less price than the adding machines now in use in banks and offices and does a much larger variety of work. It has passed the experimental stage and is being rapidly adopted in the large offices in the cities. Eight years were spent in testing the machine and making improvements before it was placed on the market. One of the machines can also be seen in the office of C. G. Spitler.
