THE AGE OF INVENTION,

A CHRONICLE OF MECHANICAL CONQUEST

By Holland Thompson

PREFATORY NOTE

This volume is not intended to be a complete record of inventive genius

and mechanical progress in the United States. A bare catalogue of

notable American inventions in the nineteenth century alone could not be

compressed into these pages. Nor is it any part of the purpose of

this book to trespass on the ground of the many mechanical works and

encyclopedias which give technical descriptions and explain in detail

the principle of every invention. All this book seeks to do is to

outline the personalities of some of the outstanding American inventors

and indicate the significance of their achievements.

Acknowledgments are due the Editor of the Series and to members of the

staff of the Yale University Press particularly, Miss Constance Lindsay

Skinner, Mr. Arthur Edwin Krows, and Miss Frances Hart--without whose

intelligent assistance the book could not have been completed in time to

take its place in the Series.

THE AGE OF INVENTION

CHAPTER I. BENJAMIN FRANKLIN AND HIS TIMES

On Milk Street, in Boston, opposite the Old South Church, lived Josiah

Franklin, a maker of soap and candles. He had come to Boston with his

wife about the year 1682 from the parish of Ecton, Northamptonshire,

England, where his family had lived on a small freehold for about three

hundred years. His English wife had died, leaving him seven children,

and he had married a colonial girl, Abiah Folger, whose father, Peter

Folger, was a man of some note in early Massachusetts.

Josiah Franklin was fifty-one and his wife Abiah thirty-nine, when the

first illustrious American inventor was born in their house on Milk

Street, January 17, 1706. He was their eighth child and Josiah's

tenth son and was baptized Benjamin. What little we know of Benjamin's

childhood is contained in his "Autobiography", which the world has

accepted as one of its best books and which was the first American book

to be so accepted. In the crowded household, where thirteen children

grew to manhood and womanhood, there were no luxuries. Benjamin's period

of formal schooling was less than two years, though he could never

remember the time when he could not read, and at the age of ten he was

put to work in his father's shop.

Benjamin was restless and unhappy in the shop. He appeared to have no

aptitude at all for the business of soap making. His parents debated

whether they might not educate him for the ministry, and his father took

him into various shops in Boston, where he might see artisans at work,

in the hope that he would be attracted to some trade. But Benjamin saw

nothing there that he wished to engage in. He was inclined to follow the

sea, as one of his older brothers had done.

His fondness for books finally determined his career. His older brother

James was a printer, and in those days a printer was a literary man as

well as a mechanic. The editor of a newspaper was always a printer and

often composed his articles as he set them in type; so "composing" came

to mean typesetting, and one who sets type is a compositor. Now James

needed an apprentice. It happened then that young Benjamin, at the age

of thirteen, was bound over by law to serve his brother.

James Franklin printed the "New England Courant", the fourth newspaper

to be established in the colonies. Benjamin soon began to write articles

for this newspaper. Then when his brother was put in jail, because he

had printed matter considered libelous, and forbidden to continue as the

publisher, the newspaper appeared in Benjamin's name.

The young apprentice felt that his brother was unduly severe and, after

serving for about two years, made up his mind to run away. Secretly he

took passage on a sloop and in three days reached New York, there to

find that the one printer in the town, William Bradford, could give him

no work. Benjamin then set out for Philadelphia. By boat to Perth Amboy,

on foot to Burlington, and then by boat to Philadelphia was the course

of his journey, which consumed five days. On a Sunday morning in

October, 1723, the tired, hungry boy landed upon the Market Street

wharf, and at once set out to find food and explore America's

metropolis.

Benjamin found employment with Samuel Keimer, an eccentric printer just

beginning business, and lodgings at the house of Read, whose daughter

Deborah was later to become his wife. The intelligent young printer soon

attracted the notice of Sir William Keith, Governor of Pennsylvania, who

promised to set him up in business. First, however, he must go to London

to buy a printing outfit. On the Governor's promise to send a letter

of credit for his needs in London, Franklin set sail; but the Governor

broke his word, and Franklin was obliged to remain in London nearly two

years working at his trade. It was in London that he printed the

first of his many pamphlets, an attack on revealed religion, called "A

Dissertation on Liberty and Necessity, Pleasure and Pain." Though he met

some interesting persons, from each of whom he extracted, according to

his custom, every particle of information possible, no future opened for

him in London, and he accepted an offer to return to Philadelphia with

employment as a clerk. But early in 1727 his employer died, and Benjamin

went back to his trade, as printers always do. He found work again in

Keimer's printing office. Here his mechanical ingenuity and general

ability presently began to appear; he invented a method of casting type,

made ink, and became, in fact, the real manager of the business.

The ability to make friends was one of Franklin's traits, and the number

of his acquaintances grew rapidly, both in Pennsylvania and New Jersey.

"I grew convinced," he naively says, "that TRUTH, SINCERITY, and

INTEGRITY in dealings between man and man were of the utmost importance

to the felicity of life." Not long after his return from England he

founded in Philadelphia the Junto, a society which at its regular

meetings argued various questions and criticized the writings of the

members. Through this society he enlarged his reputation as well as his

education.

The father of an apprentice at Keimer's furnished the money to buy a

printing outfit for his son and Franklin, but the son soon sold his

share, and Benjamin Franklin, Printer, was fairly established in

business at the age of twenty-four. The writing of an anonymous pamphlet

on "The Nature and Necessity of a Paper Currency" called attention to

the need of a further issue of paper money in Pennsylvania, and the

author of the tract was rewarded with the contract to print the money,

"a very profitable job, and a great help to me." Small favors were

thankfully received. And, "I took care not only to be in REALITY

industrious and frugal, but to avoid all appearances to the contrary. I

drest plainly; I was seen at no places of idle diversion." And, "to show

that I was not above my business, I sometimes brought home the paper I

purchased at the stores thru the streets on a wheelbarrow."

"The Universal Instructor in All Arts and Sciences and Pennsylvania

Gazette": this was the high-sounding name of a newspaper which

Franklin's old employer, Keimer, had started in Philadelphia. But

bankruptcy shortly overtook Keimer, and Franklin took the newspaper with

its ninety subscribers. The "Universal Instructor" feature of the paper

consisted of a page or two weekly of "Chambers's Encyclopedia". Franklin

eliminated this feature and dropped the first part of the long name.

"The Pennsylvania Gazette" in Franklin's hands soon became profitable.

And it lives today in the fullness of abounding life, though under

another name. "Founded A.D. 1728 by Benj. Franklin" is the proud legend

of "The Saturday Evening Post", which carries on, in our own times, the

Franklin tradition.

The "Gazette" printed bits of local news, extracts from the London

"Spectator", jokes, verses, humorous attacks on Bradford's "Mercury", a

rival paper, moral essays by the editor, elaborate hoaxes, and pungent

political or social criticism. Often the editor wrote and printed

letters to himself, either to emphasize some truth or to give him the

opportunity to ridicule some folly in a reply to "Alice Addertongue,"

"Anthony Afterwit," or other mythical but none the less typical person.

If the countryman did not read a newspaper, or buy books, he was, at

any rate, sure to own an almanac. So in 1732 Franklin brought out "Poor

Richard's Almanac". Three editions were sold within a few months. Year

after year the sayings of Richard Saunders, the alleged publisher, and

Bridget, his wife, creations of Franklin's fancy, were printed in the

almanac. Years later the most striking of these sayings were collected

and published. This work has been translated into as many as twenty

languages and is still in circulation today.

Franklin kept a shop in connection with his printing office, where he

sold a strange variety of goods: legal blanks, ink, pens, paper, books,

maps, pictures, chocolate, coffee, cheese, codfish, soap, linseed

oil, broadcloth, Godfrey's cordial, tea, spectacles, rattlesnake root,

lottery tickets, and stoves--to mention only a few of the many articles

he advertised. Deborah Read, who became his wife in 1730, looked after

his house, tended shop, folded and stitched pamphlets, bought rags,

and helped him to live economically. "We kept no idle servants,"

says Franklin, "our table was plain and simple, our furniture of the

cheapest. For instance, my breakfast was a long time bread and milk (no

tea), and I ate it out of a twopenny earthen porringer with a pewter

spoon."

With all this frugality, Franklin was not a miser; he abhorred the

waste of money, not the proper use. His wealth increased rapidly. "I

experienced too," he says, "the truth of the observation, 'THAT AFTER

GETTING THE FIRST HUNDRED POUND, IT IS MORE EASY TO GET THE SECOND,

money itself being of a prolific nature." He gave much unpaid public

service and subscribed generously to public purposes; yet he was able,

at the early age of forty-two, to turn over his printing office to one

of his journeymen, and to retire from active business, intending to

devote himself thereafter to such public employment as should come his

way, to philosophical or scientific studies, and to amusements.

From boyhood Franklin had been interested in natural phenomena. His

"Journal of a Voyage from London to Philadelphia", written at sea as he

returned from his first stay in London, shows unusual powers of exact

observation for a youth of twenty. Many of the questions he propounded

to the Junto had a scientific bearing. He made an original and important

invention in 1749, the "Pennsylvania fireplace," which, under the name

of the Franklin stove, is in common use to this day, and which brought

to the ill-made houses of the time increased comfort and a great saving

of fuel. But it brought Franklin no pecuniary reward, for he never

deigned to patent any of his inventions.

His active, inquiring mind played upon hundreds of questions in a dozen

different branches of science. He studied smoky chimneys; he invented

bifocal spectacles; he studied the effect of oil upon ruffled water;

he identified the "dry bellyache" as lead poisoning; he preached

ventilation in the days when windows were closed tight at night, and

upon the sick at all times; he investigated fertilizers in agriculture.

Many of his suggestions have since borne fruit, and his observations

show that he foresaw some of the great developments of the nineteenth

century.

His fame in science rests chiefly upon his discoveries in electricity.

On a visit to Boston in 1746 he saw some electrical experiments and at

once became deeply interested. Peter Collinson of London, a Fellow

of the Royal Society, who had made several gifts to the Philadelphia

Library, sent over some of the crude electrical apparatus of the day,

which Franklin used, as well as some contrivances he had purchased in

Boston. He says in a letter to Collinson: "For my own part, I never was

before engaged in any study that so engrossed my attention and my time

as this has lately done."

Franklin's letters to Collinson tell of his first experiments and

speculations as to the nature of electricity. Experiments made by a

little group of friends showed the effect of pointed bodies in drawing

off electricity. He decided that electricity was not the result of

friction, but that the mysterious force was diffused through most

substances, and that nature is always alert to restore its equilibrium.

He developed the theory of positive and negative electricity, or plus

and minus electrification. The same letter tells of some of the tricks

which the little group of experimenters were accustomed to play upon

their wondering neighbors. They set alcohol on fire, relighted candles

just blown out, produced mimic flashes of lightning, gave shocks

on touching or kissing, and caused an artificial spider to move

mysteriously.

Franklin carried on experiments with the Leyden jar, made an electrical

battery, killed a fowl and roasted it upon a spit turned by electricity,

sent a current through water and found it still able to ignite alcohol,

ignited gunpowder, and charged glasses of wine so that the drinkers

received shocks. More important, perhaps, he began to develop the theory

of the identity of lightning and electricity, and the possibility of

protecting buildings by iron rods. By means of an iron rod he brought

down electricity into his house, where he studied its effect upon bells

and concluded that clouds were generally negatively electrified. In

June, 1752, he performed the famous experiment with the kite, drawing

down electricity from the clouds and charging a Leyden jar from the key

at the end of the string.

Franklin's letters to Collinson were read before the Royal Society

but were unnoticed. Collinson gathered them together, and they were

published in a pamphlet which attracted wide attention. Translated into

French, they created great excitement, and Franklin's conclusions were

generally accepted by the scientific men of Europe. The Royal Society,

tardily awakened, elected Franklin a member and in 1753 awarded him the

Copley medal with a complimentary address.*

* It may be useful to mention some of the scientific facts and

mechanical principles which were known to Europeans at this time.

More than one learned essay has been written to prove the mechanical

indebtedness of the modern world to the ancient, particularly to the

works of those mechanically minded Greeks: Archimedes, Aristotle,

Ctesibius, and Hero of Alexandria. The Greeks employed the lever, the

tackle, and the crane, the force-pump, and the suction-pump. They had

discovered that steam could be mechanically applied, though they never

made any practical use of steam. In common with other ancients they

knew the principle of the mariner's compass. The Egyptians had the

water-wheel and the rudimentary blast-furnace. The pendulum clock

appears to have been an invention of the Middle Ages. The art of

printing from movable type, beginning with Gutenberg about 1450, helped

to further the Renaissance. The improved mariner's compass enabled

Columbus to find the New world; gunpowder made possible its conquest.

The compound microscope and the first practical telescope came from the

spectacle makers of Middelburg, Holland, the former about 1590 and the

latter about 1608. Harvey, an English physician, had discovered the

circulation of the blood in 1628, and Newton, an English mathematician,

the law of gravitation in 1685.

If Franklin's desire to continue his scientific researches had been

gratified, it is possible that he might have discovered some of the

secrets for which the world waited until Edison and his contemporaries

revealed them more than a century later. Franklin's scientific

reputation has grown with the years, and some of his views seem in

perfect accord with the latest developments in electricity. But he

was not to be permitted to continue his experiments. He had shown his

ability to manage men and was to be called to a wider field.

Franklin's influence among his fellow citizens in Philadelphia was very

great. Always ostensibly keeping himself in the background and working

through others, never contradicting, but carrying his point by shrewd

questions which showed the folly of the contrary position, he continued

to set on foot and carry out movements for the public good. He

established the first circulating library in Philadelphia, and one of

the first in the country, and an academy which grew into the University

of Pennsylvania. He was instrumental in the foundation of a hospital. "I

am often ask'd by those to whom I propose subscribing," said one of the

doctors who had made fruitless attempts to raise money for the hospital,

"Have you consulted Franklin upon this business?" Other public matters

in which the busy printer was engaged were the paving and cleaning of

the streets, better street lighting, the organization of a police force

and of a fire company. A pamphlet which he published, "Plain Truth",

showing the helplessness of the colony against the French and Indians,

led to the organization of a volunteer militia, and funds were raised

for arms by a lottery. Franklin himself was elected colonel of the

Philadelphia regiment, "but considering myself unfit, I declined

the station and recommended Mr. Lawrence, a fine person and man of

influence, who was accordingly appointed." In spite of his militarism,

Franklin retained the position which he held as Clerk of the Assembly,

though the majority of the members were Quakers opposed to war on

principle.

The American Philosophical Society owes its origin to Franklin. It was

formally organized on his motion in 1743, but the society has accepted

the organization of the Junto in 1727 as the actual date of its birth.

From the beginning the society has had among its members many leading

men of scientific attainments or tastes, not only of Philadelphia, but

of the world. In 1769 the original society was consolidated with another

of similar aims, and Franklin, who was the first secretary of the

society, was elected president and served until his death. The first

important undertaking was the successful observation of the transit of

Venus in 1769, and many important scientific discoveries have since been

made by its members and first given to the world at its meetings.

Franklin's appointment as one of the two Deputy Postmasters General

of the colonies in 1753 enlarged his experience and his reputation. He

visited nearly all the post offices in the colonies and introduced

many improvements into the service. In none of his positions did his

transcendent business ability show to better advantage. He established

new postal routes and shortened others. There were no good roads in the

colonies, but his post riders made what then seemed wonderful speed.

The bags were opened to newspapers, the carrying of which had previously

been a private and unlawful perquisite of the riders. Previously there

had been one mail a week in summer between New York and Philadelphia

and one a month in winter. The service was increased to three a week in

summer and one in winter.

The main post road ran from northern New England to Savannah, closely

hugging the seacoast for the greater part of the way. Some of the

milestones set by Franklin to enable the postmasters to compute the

postage, which was fixed according to distance, are still standing.

Crossroads connected some of the larger communities away from the

seacoast with the main road, but when Franklin died, after serving also

as Postmaster General of the United States, there were only seventy-five

post offices in the entire country.

Franklin took a hand in the final struggle between France and England

in America. On the eve of the conflict, in 1754, commissioners from the

several colonies were ordered to convene at Albany for a conference with

the Six Nations of the Iroquois, and Franklin was one of the deputies

from Pennsylvania. On his way to Albany he "projected and drew a plan

for the union of all the colonies under one government so far as might

be necessary for defense and other important general purposes." This

statesmanlike "Albany Plan of Union," however, came to nothing. "Its

fate was singular," says Franklin; "the assemblies did not adopt it, as

they all thought there was too much PREROGATIVE in it and in England it

was judg'd to have too much of the DEMOCRATIC."

How to raise funds for defense was always a grave problem in the

colonies, for the assemblies controlled the purse-strings and released

them with a grudging hand. In face of the French menace, this was

Governor Shirley's problem in Massachusetts, Governor Dinwiddie's in

Virginia, and Franklin's in the Quaker and proprietary province of

Pennsylvania. Franklin opposed Shirley's suggestion of a general tax to

be levied on the colonies by Parliament, on the ground of no taxation

without representation, but used all his arts to bring the Quaker

Assembly to vote money for defense, and succeeded. When General Braddock

arrived in Virginia Franklin was sent by the Assembly to confer with him

in the hope of allaying any prejudice against Quakers that the general

might have conceived. If that blustering and dull-witted soldier had any

such prejudice, it melted away when the envoy of the Quakers promised to

procure wagons for the army. The story of Braddock's disaster does not

belong here, but Franklin formed a shrewd estimate of the man which

proved accurate. His account of Braddock's opinion of the colonial

militia is given in a sentence: "He smil'd at my ignorance, and reply'd,

'These savages may, indeed, be a formidable enemy to your raw American

militia, but upon the King's regular and disciplin'd troops, sir, it is

impossible they should make any impression.'" After Braddock's defeat

the Pennsylvania Assembly voted more money for defense, and the

unmilitary Franklin was placed in command of the frontier with full

power. He built forts, as he had planned, and incidentally learned much

of the beliefs of a group of settlers in the back country, the "Unitas

Fratrum," better known as the Moravians.

The death struggle between English and French in America served only to

intensify a lesser conflict that was being waged between the Assembly

and the proprietors of Pennsylvania; and the Assembly determined to

send Franklin to London to seek judgment against the proprietors and to

request the King to take away from them the government of Pennsylvania.

Franklin, accompanied by his son William, reached London in July, 1757,

and from this time on his life was to be closely linked with Europe. He

returned to America six years later and made a trip of sixteen hundred

miles inspecting postal affairs, but in 1764 he was again sent to

England to renew the petition for a royal government for Pennsylvania,

which had not yet been granted. Presently that petition was made

obsolete by the Stamp Act, and Franklin became the representative of the

American colonies against King and Parliament.

Franklin did his best to avert the Revolution. He made many friends in

England, wrote pamphlets and articles, told comical stories and fables

where they might do some good, and constantly strove to enlighten the

ruling class of England upon conditions and sentiment in the colonies.

His examination before the House of Commons in February, 1766, marks

perhaps the zenith of his intellectual powers. His wide knowledge,

his wonderful poise, his ready wit, his marvelous gift for clear and

epigrammatic statement, were never exhibited to better advantage and no

doubt hastened the repeal of the Stamp Act. Franklin remained in England

nine years longer, but his efforts to reconcile the conflicting claims

of Parliament and the colonies were of no avail, and early in 1775 he

sailed for home.

Franklin's stay in America lasted only eighteen months, yet during that

time he sat in the Continental Congress and as a member of the most

important committees; submitted a plan for a union of the colonies;

served as Postmaster General and as chairman of the Pennsylvania

Committee of Safety; visited Washington at Cambridge; went to Montreal

to do what he could for the cause of independence in Canada; presided

over the convention which framed a constitution for Pennsylvania; was

a member of the committee appointed to draft the Declaration of

Independence and of the committee sent on the futile mission to New York

to discuss terms of peace with Lord Howe.

In September, 1776, Franklin was appointed envoy to France and sailed

soon afterwards. The envoys appointed to act with him proved a handicap

rather than a help, and the great burden of a difficult and momentous

mission was thus laid upon an old man of seventy. But no other American

could have taken his place. His reputation in France was already made,

through his books and inventions and discoveries. To the corrupt and

licentious court he was the personification of the age of simplicity,

which it was the fashion to admire; to the learned, he was a sage; to

the common man he was the apotheosis of all the virtues; to the rabble

he was little less than a god. Great ladies sought his smiles; nobles

treasured a kindly word; the shopkeeper hung his portrait on the wall;

and the people drew aside in the streets that he might pass without

annoyance. Through all this adulation Franklin passed serenely, if not

unconsciously.

The French ministers were not at first willing to make a treaty

of alliance, but under Franklin's influence they lent money to the

struggling colonies. Congress sought to finance the war by the issue of

paper currency and by borrowing rather than by taxation, and sent bill

after bill to Franklin, who somehow managed to meet them by putting

his pride in his pocket, and applying again and again to the French

Government. He fitted out privateers and negotiated with the British

concerning prisoners. At length he won from France recognition of the

United States and then the Treaty of Alliance.

Not until two years after the Peace of 1783 would Congress permit the

veteran to come home. And when he did return in 1785 his people would

not allow him to rest. At once he was elected President of the Council

of Pennsylvania and twice reelected in spite of his protests. He was

sent to the Convention of 1787 which framed the Constitution of the

United States. There he spoke seldom but always to the point, and the

Constitution is the better for his suggestions. With pride he axed his

signature to that great instrument, as he had previously signed the

Albany Plan of Union, the Declaration of Independence, and the Treaty of

Paris.

Benjamin Franklin's work was done. He was now an old man of eighty-two

summers and his feeble body was racked by a painful malady. Yet he kept

his face towards the morning. About a hundred of his letters,

written after this time, have been preserved. These letters show no

retrospection, no looking backward. They never mention "the good old

times." As long as he lived, Franklin looked forward. His interest

in the mechanical arts and in scientific progress seems never to have

abated. He writes in October, 1787, to a friend in France, describing

his experience with lightning conductors and referring to the work of

David Rittenhouse, the celebrated astronomer of Philadelphia. On the

31st of May in the following year he is writing to the Reverend John

Lathrop of Boston:

"I have long been impressed with the same sentiments you so well

express, of the growing felicity of mankind, from the improvement

in philosophy, morals, politics, and even the conveniences of common

living, and the invention of new and useful utensils and instruments;

so that I have sometimes wished it had been my destiny to be born two or

three centuries hence. For invention and improvement are prolific, and

beget more of their kind. The present progress is rapid. Many of great

importance, now unthought of, will, before that period, be produced."

Thus the old philosopher felt the thrill of dawn and knew that the day

of great mechanical inventions was at hand. He had read the meaning of

the puffing of the young steam engine of James Watt and he had heard of

a marvelous series of British inventions for spinning and weaving. He

saw that his own countrymen were astir, trying to substitute the power

of steam for the strength of muscles and the fitful wind. John Fitch on

the Delaware and James Rumsey on the Potomac were already moving vessels

by steam. John Stevens of New York and Hoboken had set up a machine shop

that was to mean much to mechanical progress in America. Oliver Evans,

a mechanical genius of Delaware, was dreaming of the application

of high-pressure steam to both road and water carriages. Such

manifestations, though still very faint, were to Franklin the signs of a

new era.

And so, with vision undimmed, America's most famous citizen lived

on until near the end of the first year of George Washington's

administration. On April 17, 1790, his unconquerable spirit took its

flight.

In that year, 1790, was taken the First Census of the United States.

The new nation had a population of about four million people. It then

included practically the present territory east of the Mississippi,

except the Floridas, which belonged to Spain. But only a small part

of this territory was occupied. Much of New York and Pennsylvania was

savage wilderness. Only the seacoast of Maine was inhabited, and the

eighty-two thousand inhabitants of Georgia hugged the Savannah River.

Hardy pioneers had climbed the Alleghanies into Kentucky and Tennessee,

but the Northwest Territory--comprising Ohio, Michigan, Indiana,

Illinois, and Wisconsin--was not enumerated at all, so scanty were its

people, perhaps not more than four thousand.

Though the First Census did not classify the population by occupation it

is certain that nine-tenths of the breadwinners worked more or less upon

the soil. The remaining tenth were engaged in trade, transportation,

manufacturing, fishing and included also the professional men, doctors,

lawyers, clergymen, teachers, and the like. In other words, nine out of

ten of the population were engaged primarily in the production of food,

an occupation which today engages less than three out of ten. This

comparison, however, requires some qualification. The farmer and the

farmer's wife and children performed many tasks which are now done in

factories. The successful farmer on the frontier had to be a jack of

many trades. Often he tanned leather and made shoes for his family and

harness for his horses. He was carpenter, blacksmith, cobbler, and often

boat-builder and fisherman as well. His wife made soap and candles, spun

yarn and dyed it, wove cloth and made the clothes the family wore, to

mention only a few of the tasks of the women of the eighteenth century.

The organization of industry, however, was beginning. Here and there

were small paper mills, glass factories-though many houses in the back

country were without glass windows--potteries, and iron foundries and

forges. Capitalists, in some places, had brought together a few

handloom weavers to make cloth for sale, and the famous shoemakers of

Massachusetts commonly worked in groups.

The mineral resources of the United States were practically unknown. The

country seems to have produced iron enough for its simple needs, some

coal, copper, lead, gold, silver, and sulphur. But we may say that

mining was hardly practiced at all.

The fisheries and the shipyards were great sources of wealth, especially

for New England. The cod fishers numbered several hundred vessels and

the whalers about forty. Thousands of citizens living along the seashore

and the rivers fished more or less to add to the local food supply. The

deep-sea fishermen exported a part of their catch, dried and salted.

Yankee vessels sailed to all ports of the world and carried the greater

part of the foreign commerce of the United States. Flour, tobacco, rice,

wheat, corn, dried fish, potash, indigo, and staves were the principal

exports. Great Britain was the best customer, with the French West

Indies next, and then the British West Indies. The principal imports

came from the same countries. Imports and exports practically balanced

each other, at about twenty million dollars annually, or about five

dollars a head. The great merchants owned ships and many of them, such

as John Hancock of Boston, and Stephen Girard of Philadelphia, had grown

very rich.

Inland transportation depended on horses and oxen or boats. There were

few good roads, sometimes none at all save bridle paths and trails.

The settlers along the river valleys used boats almost entirely.

Stage-coaches made the journey from New York to Boston in four days in

summer and in six in winter. Two days were required to go between New

York and Philadelphia. Forty to fifty miles a day was the speed of the

best coaches, provided always that they did not tumble into the ditch.

In many parts of the country one must needs travel on horseback or on

foot.

Even the wealthiest Americans of those days had few or none of the

articles which we regard today as necessities of life. The houses were

provided with open--which, however cheerful, did not keep them warm--or

else with Franklin's stoves. To strike a fire one must have the flint

and tinderbox, for matches were unknown until about 1830. Candles made

the darkness visible. There was neither plumbing nor running water. Food

was cooked in the ashes or over an open fire.

The farmer's tools were no less crude than his wife's. His plough had

been little improved since the days of Rameses. He sowed his wheat

by hand, cut it with a sickle, flailed it out upon the floor, and

laboriously winnowed away the chaff.

In that same year, 1790, came a great boon and encouragement to

inventors, the first Federal Patent Act, passed by Congress on the 10th

of April. Every State had its own separate patent laws or regulations,

as an inheritance from colonial days, but the Fathers of the

Constitution had wisely provided that this function of government should

be exercised by the nation.* The Patent Act, however, was for a

time unpopular, and some States granted monopolies, particularly of

transportation, until they were forbidden to do so by judicial decision.

* The Constitution (Article 1, Section 8, Clause 8) empowers

Congress: "To promote the Progress of Science and useful

Arts, by securing for limited Times to Authors and Inventors

the exclusive Right to their respective Writings and

Discoveries."

The first Patent Act provided that an examining board, consisting of the

Secretary of State, the Secretary of War, and the Attorney-General, or

any two of them, might grant a patent for fourteen years, if they

deemed the invention useful and important. The patent itself was to be

engrossed and signed by the President, the Secretary of State, and

the Attorney-General. And the cost was to be three dollars and seventy

cents, plus the cost of copying the specifications at ten cents a sheet.

The first inventor to avail himself of the advantages of the new Patent

Act was Samuel Hopkins of Vermont, who received a patent on the 31st of

July for an improved method of "Making Pot and Pearl Ashes." The world

knows nothing of this Samuel Hopkins, but the potash industry, which was

evidently on his mind, was quite important in his day. Potash, that is,

crude potassium carbonate, useful in making soap and in the manufacture

of glass, was made by leaching wood ashes and boiling down the lye. To

produce a ton of potash, the trees on an acre of ground would be cut

down and burned, the ashes leached, and the lye evaporated in great iron

kettles. A ton of potash was worth about twenty-five dollars. Nothing

could show more plainly the relative value of money and human labor in

those early times.

Two more patents were issued during the year 1790. The second went to

Joseph S. Sampson of Boston for a method of making candles, and the

third to Oliver Evans, of whom we shall learn more presently, for an

improvement in manufacturing flour and meal. The fourth patent was

granted in 1791 to Francis Baily of Philadelphia for making punches

for types. Next Aaron Putnam of Medford, Massachusetts, thought that

he could improve methods of distilling, and John Stone of Concord,

Massachusetts, offered a new method of driving piles for bridges. And

a versatile inventor, Samuel Mulliken of Philadelphia, received four

patents in one day for threshing grain, cutting and polishing marble,

raising a nap on cloth, and breaking hemp.

Then came improvements in making nails, in making bedsteads, in the

manufacture of boats, and for propelling boats by cattle. On August 26,

1791, James Rumsey, John Stevens, and John Fitch (all three will appear

again in this narrative) took out patents on means of propelling boats.

On the same day Nathan Read received one on a process for distilling

alcohol.

More than fifty patents were granted under the Patent Act of 1790, and

mechanical devices were coming in so thick and fast that the department

heads apparently found it inconvenient to hear applications. So the

Act of 1790 was repealed. The second Patent Act (1793) provided that a

patent should be granted as a matter of routine to any one who swore to

the originality of his device and paid the sum of thirty dollars as a

fee. No one except a citizen, however, could receive a patent. This act,

with some amendments, remained in force until 1836, when the present

Patent Office was organized with a rigorous and intricate system for

examination of all claims in order to prevent interference. Protection

of the property rights of inventors has been from the beginning of the

nation a definite American policy, and to this policy may be ascribed

innumerable inventions which have contributed to the greatness of

American industry and multiplied the world's comforts and conveniences.

Under the second Patent Act came the most important invention yet

offered, an invention which was to affect generations then unborn. This

was a machine for cleaning cotton and it was offered by a young Yankee

schoolmaster, temporarily sojourning in the South.
