The Melodette, or Automatic Piano,

The most marvellous mechanical invention of the age. It will play any tune that ever was written, in a melodious and pleasing manner. Difficult and simple music produced in a masterly style, and it can be played by a child as well as by a grown person, and will furnish music for social gatherings of any description, playing hour after hour, without any knowledge of music being required in the operation. The most wonderful of all musical inventions; a machine which in a purely mechanical manner produces any kind of music, Waltzes, Polkas, Marches, &c., &c., without any practice or knowledge of music whatever; in this respect far superior to any music-box, even though it costs many times as much, for there is no limit whatever to the number of tunes it will play. This instrument is on a somewhat similar principle to the wonderful Phonograph, the perforations in a flexible strip producing the effect. It has just been perfected (the accompanying cut showing it in its improved form), and is having the largest sale ever obtained by a musical instrument in the country. It has solid metal cases in imitation of green bronze; the notes or bars (the music producers) are metal, on same principle as a tuning-fork, which produce clear and most melodious notes, and never get out of tune; the bars are struck by strikers, the same as the wires are in a piano, only they work automatically instead of by the fingers. The strip of prepared paper in which the tune is stamped or perforated, is about 10 inches wide, and as it passes through the rollers and over the keys the strikers spring through the perforations in the paper and strike the right note; this is all done automatically, without any assistance from the operator (except turning the rollers), and the tune is played perfectly. It would be one of the most appropriate presents to make anyone, especially where there is no other musical instrument. Its execution is admirable, and its capacity or capability almost unlimited. It is selling faster than any musical instrument ever invented. The music is fine, and everybody delighted. The regular retail price of the Melodette is only $5, including a selection of popular tunes. Address, The Massachusetts Organ Co., 57 Washington Street Boston, Mass., U. S. A., Sole Manufacturers. SPECIAL OFFER--Agents Wanted--We wish a good Agent in every town, and big money can be made selling these instruments. We will send a sample instrument to any one wishing to act as our agent, for $3.25, Boxed Free, including music price lists, etc., etc., and will give territory. Order at once. $50 a week easily made. _We have 1000 testimonials_.

PROPOSALS FOR MAIL LOCKS.

POST OFFICE DEPARTMENT, WASHINGTON. D. C., October 23, 1880.

SEALED PROPOSALS will be received at this Department, until 12 o'clock, noon, on the 26th day of January, 1881, for furnishing a new kind of mail locks and keys for the sole and exclusive use of the United States through registered mails.

As the public exposure and searching examination necessary to intelligent bidding on any prescribed model of a lock and key would tend to impair, if not entirely destroy, the further utility of such locks and keys for the purposes of the mails, the Postmaster General prescribes no model or sample for bidders, but relies for a selection on the mechanical skill and ingenuity which a fair competition among inventors, hereby invited, may develop in samples submitted by them.

Specifications of the conditions and requirements relating to proposals, samples, contract, etc., as well as forms of proposal, will be furnished on application by letter to the Second Assistant Postmaster General.

No proposal will be considered unless it shall have been submitted in accordance with such specification and forms.

The contracts which may be made will be in conformity to the specifications and the accepted proposal. But the right is, however, reserved to reject any and all of the proposals.
