A WORD TO BUSINESS MEN.

You cannot afford to do your writing in the old way. The work of our machines is plain and business-like, obviating all mistakes in reading. Several copies can be made at one writing by the use of carbon paper. Excellent letterpress copies can be taken. Our improved machine has been adopted in all the Departments of the Government Service, and is being very generally introduced by all leading business houses. Does not this argue that the Typewriter should be worth something to you? The Machines can be furnished with special key-boards to suit any purchaser's line of business.
