with the quill pen。 One great difficulty to be

overcome was their extreme hardness and stiffness;

this was effected by making slits at the side in addition

to the central one; which had previously been

solely used。 A further improvement; that of cross

grinding the points; was subsequently adopted。 The

first gross of pens with three slits was sold for seven

pounds。 In 1830 the price was 2。00; in 1832; 1。50;

in 1861; 12 cents; and a common variety for 4 cents a

gross。 About 9;300 tons of steel are annually

consumed; the number of pens produced in England alone

being about 8;000;000;000。



Bramah patented quill nibs made by splitting

quills and cutting the semicylinders into sections

which were shaped into pens and adapted to be

placed in a holder。 These were; perhaps; the first

nibs; the progenitors of a host of steel; gold; and

other pens。



Hawkins and Mordan; in 1823; made nibs of horn

and tortoise shell; instead of quill。 The tortoise shell

being softened; points of ruby and diamond were imbedded。

Metallic points were also cemented to the

shell nibs。



Doughty; about 1825; made gold pens with ruby

points。



Gold pens with rhodium or iridium points were

introduced soon afterwards。



Mordan's oblique pen; English patent; 1831; was

designed to present the nibs in the right direction

while preserving the customary positions of the pen

and hand。



The fountain pen carries a supply of ink; fed gradually

to the point of the instrument。 The first made

by Scheffer was introduced about 1835 by Mordan。

The pressure of the thumb on a stud in a holder

caused a continuous supply of ink to flow from the

reservoir to the pen。



The 〃stylographic〃 is a reservoir pen shaped like

a pencil; in which the flow of ink is regulated by

pressure of a style or fine needle with blunt point

upon the paper。 It must be held in a vertical position。

All marks made with one; both up and down

strokes; are equal in width。



Gold pens are now usually tipped with iridium;

making what are commonly known as diamond points。



〃The iridium for this purpose is found in small

grains of platinum; slightly alloyed with this latter

metal。 The gold for pens is alloyed with silver to

about sixteen carats fineness; rolled into thin strips;

from which the blanks are struck。 The under side

of the point is notched by a small circular saw to

receive the iridium point; which is selected with the

aid of a microscope。 A flux of borax and a blowpipe

secure it to its place。 The point is then ground

on a copper wheel of emery。 The pen…blank is next

rolled to the requisite thinness by the means of rollers

especially adapted for the purpose; and tempered

by blows from a hammer。 It is then trimmed

around the edges; stamped; and formed in a press。

The slit is next cut through the solid iridium point

by means of a thin copper wheel fed with fine emery;

and a saw extends the aperture along the pen itself。

The inside edges of the slit are smoothed and polished

by the emery wheel; burnishing and hammering

produce the proper degree of elasticity。〃



It is asserted that more steel is used in the manufacture

of pens than in all the swords and guns in the

world。 This fact partly verifies the old saying; 〃The

pen is mightier than the sword。〃



 〃Three things bear mighty sway with men;

 The Sword; the Sceptre; and the Pen;

 Who can the least of these command;

 In the first rank of Fame will stand。〃

SUBSTITUTES FOR INK UTENSILS (〃LEAD〃 AND OTHER

THE black…lead pencil; under many circumstances;

is a very useful substitute for the pen; in that it

requires no liquid ink for marking the characters on

paper or other materials。 The peculiar substance

which fills the central channel of the stick of cedar

has the property of marking when it touches paper;

and; as the marks thus made are susceptible to easy

removal; a pencil of this kind is available for purposes

which would not be answered by the use of pen and ink。



The substance misnamed 〃black…lead〃 contains NO

LEAD and is a carburet of iron; being composed of

carbon and iron。 It generally occurs in Mountain districts;

in small kidney…shaped pieces; varying in size

from that of a pea upwards; which are interspersed

among various strata; and is met with in different

parts of the world。



Its principal source of supply until about 1845;

when it became exhausted; was the Borrowdale mine

in Cumberland; England; which was discovered in

1564。 About 1852 a number of mines were opened

containing this substance in Siberia and from which

place the best products are now obtained。



The accidental discovery of this mineral at Borrowdale

was during the reign of Queen Elizabeth who

made many inquiries about it。 The name of this

mineral was locally known as wad (graphite)。 So

valuable was it regarded that it commanded a very

high price; and this price acted as in inducement to

the workmen and others to pilfer pieces from the

mine。 For a number of years scenes of great commotion

took place; arising out of these depredations; and

the result was that the proprietors adopted such

stringent rules that hardly anything was known of

the internal economy of the mine till about sixty

years ago; when Mr。 Parkes gave a description of it;

from which I may condense a few particulars。



The mine is in the midst of a mountain about two

thousand feet high; which rises at in angle of about

45 degrees; and; as that part of the mine which has been

worked during the last century is near the middle

of the mountain; the present entrance is about a

thousand feet from the summit。 The opening by

which the workmen enter descends by a flight of

steps; and in order to guard the treasure within; the

proprietors have erected a strong brick building of

four rooms; one of which is immediately over the

entrance into the mine。 This entrance is secured by a

trap…door; and the room connected with it serves as a

dressing…room for the men when they enter and leave

the mine。 The men work in gangs; which relieve

each other every six hours; and when the hour of

relief comes; a steward or foreman attends the dressing…

room to see the men change their dresses as they

come up one by one out of the mine。 The clothes

are examined by the steward to see that no black…lead

is concealed in them; and when the men have dressed

they leave the mine; making room for another gang;

who change their clothes; enter the mine; and are fastened

in for six hours。 In one of the four rooms of which

the house consists there is a table; at which men are

employed in sorting and dressing the mineral。 This is

necessary; because it is usually divided into two qualities;

the finest of which have generally pieces of iron…

ore or other impurity attached to them; which must

be dressed off。 These men; who are strictly watched

while at work; put the dressed black…lead into casks

holding about one hundred…weight each; in which state

it leaves the mine。 The casks are conveyed down

the side of the mountain in a curious manner。 Each

cask is fixed upon a light sledge with two wheels;

and a man; who is well used to the precipitous path;

walks down in front of the sledge; taking care that it

does not acquire momentum enough to overpower

him。 When the cask has been thus guided sa
