A PERFECT SALESMAN

THE IDEAL postal clerk who never gives five twos for two fives and never argues with patrons, is being tried out in the post-office in Washington, D. C. As might have been guessed, it is an automatic machine which dispenses stamps and makes change quickly without charge.

If the machine proves successful, it is probable that similar ones will be installed throughout the country by the government.
