Chapter M: B. W.--No. 1 is a silicious clay--it might be useful in the

manufacture of some grades of pottery, etc. No. 2 is a ferruginous shale--contains about 80 per cent. of silica and 10 per cent. of alumina, besides lime, magnesia, iron oxide, and water.--W. S.--It is fibrous talc--talc of good quality is in considerable demand for paper making and other purposes.--W. G. H.--The sand contains no precious metal--the glittering particles are mica.--S. F.--The specimen you send consists of a mass of the long hairs which have been attached to the seeds of the "milkweed" (_asclepias_), or, as it is sometimes called, from the silky nature of these appendages, "silkweed." We believe that this material is put to no other economic use at present than that of a filling for cushions and pillows. The beauty of this silk like down long ago attracted attention, and many unsuccessful attempts have been made to put it to some practical use in the arts; but, as you have probably noticed, the hairs are both brittle and weak, and an examination with a lens will show that it wants the roughness and angularity necessary to fit it for being spun like other fibers. It has, however, been mixed with cotton and woven into fabrics having a silky luster and capable of taking brilliant dyes, but the manufacture has never been prosecuted. The plants, though widely distributed over the United States, and quite common, are nevertheless not abundant enough in a wild state to afford much of a supply, and we believe no experiments have been made in cultivating them.

CAVEATS, COPYRIGHTS, TRADE MARKS, ETC.

Messrs. Munn & Co., in connection with the publication of the SCIENTIFIC AMERICAN, continue to examine Improvements, and to act as Solicitors of Patents for Inventors.

In this line of business they have had OVER THIRTY YEARS' EXPERIENCE, and now have _unequaled facilities_ for the preparation of Patent Drawings, Specifications, and the Prosecution of Applications for Patents in the United States. Canada, and Foreign Countries. Messrs. Munn & Co. also attend to the preparation of Caveats, Trade Mark Regulations, Copyrights for Books, Labels, Reissues, Assignments, and Reports on Infringements of Patents. All business intrusted to them is done with special care and promptness, on very moderate terms.

We send free of charge, on application, a pamphlet containing further information about Patents and how to procure them; directions concerning Trade Marks, Copyrights, Designs, Patents, Appeals, Reissues, Infringements, Assignments, Rejected Cases, Hints on the Sale of Patents, etc.

_FOREIGN PATENTS._--We also send, _free of charge_, a Synopsis of Foreign Patent Laws, showing the cost and method of securing patents in all the principal countries of the world. American inventors should bear in mind that, as a general rule, any invention that is valuable to the patentee in this country is worth equally as much in England and some other foreign countries. Five patents--embracing Canadian, English, German, French, and Belgian--will secure to an inventor the exclusive monopoly to his discovery among about ONE HUNDRED AND FIFTY MILLIONS of the most intelligent people in the world. The facilities of business and steam communication are such that patents can be obtained abroad by our citizens almost as easily as at home. The expense to apply for an English patent is $75; German, $100; French, $100; Belgian, $100; Canadian, $50. _COPIES OF PATENTS._--Persons desiring any patent issued from 1836 to November 26, 1867, can be supplied with official copies at reasonable cost, the price depending upon the extent of drawings and length of specifications.

Any patent issued since November 27, 1867, at which time the Patent Office commenced printing the drawings and specifications, may be had by remitting to this office $1.

A copy of the claims of any patent issued since 1836 will be furnished for $1.

When ordering copies, please to remit for the same as above, and state name of patentee, title of invention, and date of patent.

A pamphlet, containing full directions for obtaining United States patents sent free. A handsomely bound Reference Book, gilt edges, contains 140 pages and many engravings and tables important to every patentee and mechanic, and is a useful hand book of reference for everybody. Price 25 cents, mailed free.

_The most profitable plan_ for operating in stocks is by uniting capital of various sums in combining or pooling orders of thousands of customers and using them as _one mighty whole_, which is done so successfully by Messrs. Lawrence & Co., Bankers, 57 Exchange Place, N. Y. City. By this cooperative system each investor is placed on an equal footing with the largest operator and profits divided _pro rata_ among shareholders every 30 days. $10 invested makes $50 or 5 per cent. on the stock during the month--$50 returns $350 or 7 per cent., $100 pays $1,000, or 10 per cent., and so on according to the market. The firm's new circular (copyrighted and free) contains "Two unerring rules for success in stock operations," and explains everything. All kinds of Stocks and Bonds wanted. New Government Loan supplied. LAWRENCE & CO., _Bankers and Brokers_, 57 Exchange Place, N. Y. City.
