Last year [1910] fifteen billion letters were handled by the post office--one hundred and fifty for every person. Just as a thousand years ago practically all trade was cash, and now only seven per cent involves currency, so nine-tenths of the business is done today by letter while even a few decades ago it was by personal word. You can get your prospect, turn him into a customer, sell him goods, settle complaints, investigate credit standing, collect your money_--ALL BY LETTER. _And often better than by word of mouth. For, when talking, you speak to only one or two; by letter you can talk to.
