Oil, each one-half ounce.
BARBER'S SHAMPOOING MIXTURE. Soft Water one pint,

CRUCIBLES. The best crucibles are made of a pure fire clay,
mixed with finely ground cement of oil crucibles, and a portion of black
lead or graphite; some pounded coke may be mixed with the plumbago.
The clay should be prepared in a similar way as for making pottery ware.
The vessels, after being formed, must be slowly dried, and then properly
baked in a kiln.
Black Lead Crucibles are made of two parts of Graphite and one
of Fire Clay, mixed with Water into a paste, pressed in moulds, and well
dried, but not baked hard in the kiln. This compound forms excellent
small or portable furnaces.
WHAT TO INVENT, AND HOW TO PROTECT YOUR INVENTION.
WHAT TO INVENT. Cheap, useful articles that will sell at
sight. Something that everyone needs, and the poorest can afford. In
vent simple things for the benefit of the masses, and your fortune is
made. Some years back a one-armed soldier amassed a fortune from a
single toy a wooden ball attached to a rubber string. They cost scarcely
anything, yet millions were sold at a good price. A German became enor
mously rich by patenting a simple wooden plug for toeer barrels. "What
man has done, man may do."
HOW TO PROTECT YOUR INVENTION. Patent it. If you
do"iiot, others will reap the benefits that rightfully belong to you.
A PATENT IS A PROTECTION given to secure the inventor in
the profits arising from the manufacture and sale of an article of his
own creation.
TO WHOM LETTERS PATENT ARE GRANTED. Section
4886 of the Revised Statutes of the United States provides that: "Any
person who has invented or discovered any new and useful art, machine,
manufacture or composition of matter, or any new and useful improve
ment thereof, not known or used by others in this country, and not
patented or described in any printed publication in this or any foreign
country, before his invention or discovery thereof, and not in public
use, or on sale for more than two years prior to his application, unless
the same is proved to have been abandoned, may, upon the payment of

And section 4888 of the same Statute enacts:
Section 4888. Before any inventor or discoverer shall receive a
patent for his invention or discovery, he shall make application therefor,
in writing, to the Commissioner of Patents, and shall file in the Patent
Office a written description of the same, and of the manner and pro
cess of making, constructing, compounding, and using it, in such full,
clear, concise and exact terms, as to enable any person skilled in the
art or science to which it appertains, or with which it is most nearly
connected, to make, construct, compound, and use the same; and in case
of a machine, he shall explain the principle thereof and the best mode in
which he has contemplated applying that principle, so as to distinguish
it from other inventions; and he shall particularly point out and dis
tinctly claim that part, improvement or combination which he claims
as his invention or discovery. The specification and claim shall be signed
by the inventor and attested by two witnesses.
It is also required by law that when "The case admits of drawings,"
it shall be properly illustrated; and also, if the Commissioner requires it,
that a model shall be furnished in cases capable of such demonstration.

final Government fees, to be paid within six months from date of allow

CAVEATS. A caveat is a confidential communication used in the
Patent Office, and it consists of a specification, drawings, oath and peti
tion. The specification must contain a clear description of the intended
invention.
HOW A COPYRIGHT IS SECURED. The method by which a
copyright is obtained under the revised acts of Congress is as simple
and inexpensive as can be reasonably asked. All unnecessary red tape is
dispensed with, and the cost to the author who is seeking thus to pro-
