CARD-TELEGRAMS.

Great as have been recent improvements in our postal service, we have yet to learn something from the Parisians, whose system of Card-telegrams is worthy of notice. The cards are of two kinds—namely, yellow similar to our own, and blue, which, when secrecy is desired, may be closed. By dropping the card into the Card Telegram Box at the nearest telegraph office, it is shot through one of the pneumatic tubes which are now being extended all over Paris, and is delivered at its destination within half an hour. Fifty to seventy words can be written on the card, the cost of which is threepence. It is further intended to permit of cards being dropped into the boxes up to fifteen minutes of the departure of the mail-trains, a boon which merchants in Great Britain may well envy.
