DELIVERY OF LETTERS.
A short time ago a correspondent suggestel, in order to expedite the delivery of letters, that an aperture should be cut in street-doors. A
• Mr. DOWNER, following up this idea, has invented a letterbox to be fastened to doors; which, besides security and convenience, has the in- genious feature of sounding an alarum that may be distinctly heard all over the house simultaneously with the dropping of the letter into the box. A model may be seen at Mr. HooeDit's, 13, Pall Mall East. There is evidence to show that if all letters were prepaid and the post- man not delayed at the doors, letters would be delivered in one-twen- tieth part of the time they now take.
The carriers in all quarters of the country arc suffering severely from the operation of the penny postage. The contraband traffic in letters was a pretty goad paying part of the business of country carriers for- merly.—Glusgow Chronicle.
