PRODUCED BY THEIR GENIUS IN AMERICA.

From the moment slavery gained a foothold in North America until the direful hour that witnessed its dissolution amid the shock of embattled arms, learning was the forbidden fruit that no Negro dared taste. Positive and explicit statutes everywhere, as fiery swords, drove him away hungry from the tree of intellectual life; and all persons were forbidden to pluck the fruit for him, upon pain of severe penalties. Every yearning for intellectual food was answered by whips and thumb-screws.

But, notwithstanding the state of almost instinctive ignorance in which slavery held the Negro, there were those who occasionally astounded the world with the brightness of their intellectual genius. There were some Negroes whose minds ran the gauntlet of public proscription on one side and repressive laws on the other, and safely gained eminence in _astronomy, mathematics_, and _medicine_.

BANNEKER THE ASTRONOMER.

BENJAMIN BANNEKER, the Negro _astronomer_ and _philosopher_, was born in Maryland, on the 9th of November, 1731. His maternal grandmother was a white woman, a native of England, named _Molly Welsh_. She came to Maryland in a shipload of white emigrants, who, according to the custom of those days, were sold to pay their passage. She served her master faithfully for seven years, when, being free, she purchased a small farm, at a nominal price. Soon after she bought two Negro slaves from a ship that had come into the Chesapeake Bay, and began life anew. Both of these Negroes proved to be men of more than ordinary fidelity, industry, and intelligence. One of them, it was said, was the son of an African king. She gave him his freedom, and then married him. His name was Banneker.[612] Four children were the fruit of this union; but the chief interest centres in only one,--a girl, named Mary. Following the example of her mother, she also married a native of Africa: but both tradition and history preserve an unbroken silence respecting his life, with the single exception that, embracing the Christian religion, he was baptized "Robert Banneker;" and the record of his death is thus preserved, in the family Bible: "_Robert Banneker departed this life, July 'ye_ 10th 1759." Thus it is evident that he took his wife's surname. Benjamin Banneker was the only child of Robert and Mary Banneker.

Young Benjamin was a great favorite with his grandmother, who taught him to read. She had a sincere love of the Sacred Scriptures, which she did not neglect to inculcate into the youthful heart of her grandson. In the neighborhood,--at that time an almost desolate spot,--a school was conducted where the master admitted several Colored children, with the whites, to the benefits of his instructions. It was a "pay school," and thither young Banneker was sent at a very tender age. His application to his studies was equalled by none. When the other pupils were playing, he found great pleasure in his books. How long he remained in school, is not known.

His father purchased a farm of one Richard Gist, and here he spent the remnant of his days.

When young Banneker had obtained his majority, he gave attention to the various interests of farm-life. He was industrious, intelligent in his labors, scrupulously neat in the management of his grounds, cultivated a valuable garden, was gentle in his treatment of stock,--horses, cows, etc.,--and was indeed comfortably situated. During those seasons of leisure which come to agriculturists, he stored his mind with useful knowledge. Starting with the Bible, he read history, biography, travels, romance, and such works on general literature as he was able to borrow. His mind seemed to turn with especial satisfaction to mathematics, and he acquainted himself with the most difficult problems.

He had a taste also for mechanics. He conceived the idea of making a timepiece, a clock, and about the year 1770 constructed one. With his imperfect tools, and with no other model than a borrowed watch, it had cost him long and patient labor to perfect it, to make the variation necessary to cause it to strike the hours, and produce a concert of correct action between the hour, the minute, and the second machinery. He confessed that its regularity in pointing out the progress of time had amply rewarded all his pains in its construction.[613]

In 1773 Ellicott & Co. built flour-mills in a valley near the banks of the Patapsco River. Banneker watched the mills go up; and, when the machinery was set in motion, looked on with interest, as he had a splendid opportunity of observing new principles of mechanism. He made many visits to the mills, and became acquainted with their proprietors; and, till the day of his death, he found in the Ellicotts kind and helpful friends.

After a short time the Ellicotts erected a store, where, a little later, a post-office, was opened. To this point the farmers and gentlemen, for miles around, used to congregate. Banneker often called at the post-office, where, after overcoming his natural modesty and diffidence, he was frequently called out in conversations covering a variety of topics. His conversational powers, his inexhaustible fund of information, and his broad learning (for those times and considering his circumstances), made him the connoisseur of that section. At times he related, in modest terms, the difficulties he was constrained to encounter in order to acquire the knowledge of books he had, and the unsatisfied longings he still had for further knowledge. His fame as a mathematician was already established, and with the increasing facilities of communication his accomplishments and achievements were occupying the thought of many intelligent people.

"By this time he had become very expert in the solution of
difficult mathematical problems, which were then, more than
in this century, the amusement of persons of leisure, and
they were frequently sent to him from scholars residing in
different parts of our country who wished to test his
capacity. He is reported to have been successful in every
case, and, sometimes, he returned with his answers,
questions of his own composition conveyed in rhyme."

The following question was propounded to Mr. George Ellicott, and was solved by Benjamin Hallowell of Alexandria.

"A Cooper and Vintner sat down for a talk,
Both being so groggy, that neither could walk,
Says Cooper to Vintner, 'I'm the first of my trade,
There's no kind of vessel, but what I have made,
And of any shape, Sir,--just what you will,--
And of any size, Sir,--from a ton to a gill!'
'Then,' says the Vintner, 'you're the man for me,--
Make me a vessel, if we can agree.
The top and the bottom diameter define,
To bear that proportion as fifteen to nine;
Thirty-five inches are just what I crave,
No more and no less, in the depth, will I have;
Just thirty-nine gallons this vessel must hold,--
Then I will reward you with silver or gold,--
Give me your promise, my honest old friend?'
'I'll make it to-morrow, that you may depend!'
So the next day the Cooper his work to discharge,
Soon made the new vessel, but made it too large:--
He took out some staves, which made it too small,
And then cursed the vessel, the Vintner and all.
He beat on his breast, 'By the Powers!'--he swore,
He never would work at his trade any more!
Now my worthy friend, find out, if you can,
The vessel's dimensions and comfort the man!

"BENJAMIN BANNEKER."

The greater diameter of Banneker's tub must be 24.746 inches; the less diameter, 14.8476 inches.

He was described by a gentleman who had often met him at Ellicott's Mills as "of black complexion, medium stature, of uncommonly soft and gentlemanly manners and of pleasing colloquial powers."

Fortunately Mr. George Ellicott was a gentleman of exquisite literary taste and critical judgment. He discovered in Banneker the elements of a cultivated gentleman and profound scholar. He threw open his library to this remarkable Negro, loaded him with books and astronomical instruments, and gave him the emphatic assurance of sympathy and encouragement. He occasionally made Banneker a visit, when he would urge upon him the importance of making astronomical calculations for almanacs. Finally, in the spring of 1789, Banneker submitted to Mr. Ellicott his first projection of an eclipse. It was found to contain a slight error; and, having kindly pointed it out, Mr. Ellicott received the following reply from Banneker:--

LETTER OF BENJAMIN BANNEKER TO GEORGE ELLICOTT.

"Sir,--I received your letter at the hand of Bell but found
nothing strange to me In the Letter Concerning the number of
Eclipses, the according to authors the Edge of the penumber
only touches the Suns Limb in that Eclips, that I left out
of the Number--which happens April 14th day, at 37 minutes
past 7 o'clock in the morning, and is the first we shall
have; but since you wrote to me, I drew in the Equations of
the Node which will cause a small Solar Defet, but as I did
not intend to publish, I was not so very peticular as I
should have been, but was more intent upon the true method
of projecting; a Solar Eclips--It is an easy matter for us
when a Diagram is laid down before us, to draw one in
resemblance of it, but it is a hard matter for young Tyroes
in Astronomy, when only the Elements for the projection is
laid down before him to draw his diagram with any degree of
Certainty.

"Says the Learned LEADBETTER, the projection, I shall here
describe, is that mentioned by Mr. Flamsted. When the sun is
in Cancer, Leo, Virgo, Libra, Scorpio or, Sagitary, the Axes
of the Globe must lie to the right hand of the Axes of the
Ecliptic, but when the sun is in Capricorn, Aquarius,
Pisces, Aries, Taurus, or Gemini, then to the left.

"Says the wise author FERGUSON, when the sun is in
Capercorn, Aquarius, Pisces, Aries, Taurus, and Gemeni, the
Northern half of the Earths Axes lies to the right hand of
the Axes of the Ecliptic and to the left hand, whilst the
Sun is on the other six signs.

"Now Mr. Ellicott, two such learned gentlemen as the above
mentioned, one in direct opposition to the other, stagnates
young beginners, but I hope the stagnation will not be of
long duration, for this I observe that Leadbetter counts the
time on the path of Vertex 1, 2, 3 &c. from the right to the
left hand or from the consequent to the antecedent,--But
Ferguson on the path of Vertex counts the time 1, 2, 3 &c.
from the left to the right hand, according to the order of
numbers, so that that is regular, shall compensate for
irregularity. Now sir if I can overcome this difficulty I
doubt not being able to calculate a Common Almanac--Sir no
more

"But remain your faithful friend,
"B. BANNEKER.

"Mr. GEORGE ELLICOTT, _Oct. 13th, 1789._"

His mother, an active, intelligent, slight-built Mulatto, with long black hair, had exercised a tender but positive influence over him. His character, so far as is known, was without blemish, with the single exception of an occasional use of ardent spirits. He found himself conforming too frequently to the universal habit of the times, social drinking. Liquors and wines were upon the tables and sideboards of the best families, and wherever Banneker went it confronted him. He felt his weakness in this regard, and resolved to abstain from the use of strong drink. Some time after returning from a visit to Washington, in company with the commissioners who laid out the District of Columbia, he related to his friends that during the entire absence from home he had abstained from the use of liquors; adding, "I feared to trust myself even with wine, lest it should steal away the little sense I have." On a leaf of one of his almanacs, appears the following in his own handwriting:--

"Evil communications corrupt good manners, I hope to live to
hear, that good communication corrects 'bad manners.'"

He had a just appreciation of his own strength. He hated vice of every kind; and, while he did not connect himself to any church, he was deeply attached to the _Society of Friends._ He was frequently seen in their meeting-house. He usually occupied the rear bench, where he would sit with uncovered head, leaning upon his staff, wrapt in profound meditation. The following letter addressed to Mr. J. Saurin Norris shows that his character was upright:--

"In the year 1800, I commenced my engagements in the store
of Ellicott's Mills, where my first acquaintance with
Benjamin Banneker began. He often came to the store to
purchase articles for his own use; and, after hearing him
converse, I was always anxious to wait upon him. After
making his purchases, he usually went to the part of the
store where George Ellicott was in the habit of sitting to
converse with him about the affairs of our Government and
other matters. He was very precise in conversation and
exhibited deep reflection. His deportment whenever I saw
him, appeared to be perfectly upright and correct, and he
seemed to be acquainted with every thing of importance that
was passing in the country.

"I recollect to have seen his Almanacs in my father's house,
and believe they were the only ones used in the neighborhood
at the time. He was a large man inclined to be fleshy, and
was far advanced in years, when I first saw him, I remember
being once at his house, but do not recollect any thing
about the comforts of his establishment, nor of the old
clock, about which you enquired. He was fond of, and well
qualified, to work out abstruse questions in arithmetic. I
remember, he brought to the store, one which he had composed
himself, and presented to George Ellicott for solution. I
had a copy which I have since lost; but the character and
deportment of the man being so wholly different from any
thing I had ever seen from one of his color, his question
made so deep an impression on my mind I have ever since
retained a perfect recollection of it, except two lines,
which do not alter the sense. I remember that George
Ellicott, was engaged in making out the answer, and cannot
now say that he succeeded, but have no doubt he did. I have
thus, briefly given you my recollections of Benjamin
Banneker. I was young when he died, and doubtless many
incidents respecting him, have, from the time which has
since elapsed, passed from my recollection:

"CHARLES W. DORSEY, _of Elkridge_."

After the death of his mother, Banneker dwelt alone until the day of his death, having never married, his manners were gentle and engaging, his benevolence proverbial. His home became a place of great interest to visitors, whom he always received cordially, and treated hospitably all who called.

"We found the venerable star-gazer," says the author of the
Memoir of Susanna Mason, "under a wide spreading pear tree,
leaden with delicious fruit; he came forward to meet us, and
bade us welcome to his lowly dwelling. It was built of logs,
one story in height, and was surrounded by an orchard. In
one corner of the room, was suspended a clock of his own
construction, _which_ was a true hearald of departing hours.
He was careful in the little affairs of life as well as in
the great matters. He kept record of all his business
transactions, literary and domestic. The following extracts
from his Account Book exhibit his love for detail.

"'Sold on the 2nd of April, 1795, to Buttler, Edwards &
Kiddy, the right of an Almanac, for the year 1796, for the
sum of 80 dollars, equal to £30.

"'On the 30th of April, 1795, lent John Ford five dollars.
£1 17s. 6d.

"'12th of December, 1797, bought a pound of candles at 1s.
8d.

"'Sold to John Collins 2 qts. of dried peaches 6d. "1 qt.
mead 4d.

"'On the 26th of March, came Joshua Sanks with 3 or 4
bushels of turnips to feed the cows.

"'13th of April, 1803, planted beans and sowed cabbage
seed.'

"He took down from a shelf a little book, wherein he
registered the names of those, by whose visits he felt
particularly honored, and recorded my mother's name upon the
list; he then, diffidently, but very respectfully, requested
her acceptance of one of his Almanacs in manuscript."

Within a few days after this visit Mrs. Mason addressed him in a poetical letter, which found its way into the papers of the section, and was generally read. The subjoined portions are sufficient to exhibit the character of the effusion. The admonitory lines at the end doubtless refer to his early addiction to strong drink.

"_An Address to_ BENJAMIN BANNEKER, _an African Astronomer,
who presented the Author with a Manuscript Almanac in_
1796."

"Transmitted on the wings of Fame,
Thine _eclat_ sounding with thy name,
Well pleased, I heard, ere 'twas my lot
To see thee in thy humble cot.
That genius smiled upon thy birth,
And application called it forth;
That times and tides thou could'st presage,
And traverse the Celestial stage,
Where shining globes their circles run,
In swift rotation round the sun;
Could'st tell how planets in their way,
From order ne'er were known to stray.
Sun, moon and stars, when they will rise,
When sink below the upper skies,
When an eclipse shall veil their light,
And hide their splendor from our sight.
. . . . . . . . .
Some men whom private walks pursue,
Whom fame ne'er ushered into view,
May run their race, and few observe
To right or left, if they should swerve,
Their blemishes would not appear,
Beyond their lives a single year.--
But thou, a man exalted high,
Conspicuous in the world's keen eye,
On record now, thy name's enrolled,
And future ages will be told,--
There lived a man named BANNEKER,
An African Astronomer!--
Thou need'st to have a special care,
Thy conduct with thy talent square,
That no contaminating vice,
Obscure thy lustre in our eyes."

During the following year Banneker sent the following letter to his good friend Mrs. Mason:--

"_August 26th, 1797_.

"DEAR FEMALE FRIEND:--

"I have thought of you every day since I saw you last, and
of my promise in respect of composing some verses for your
amusement, but I am very much indisposed, and have been
ever since that time. I have a constant pain in my head, a
palpitation in my flesh, and I may say I am attended with a
complication of disorders, at this present writing, so that
I cannot with any pleasure or delight, gratify your
curiosity in that particular, at this present time, yet I
say my will is good to oblige you, if I had it in my power,
because you gave me good advice, and edifying language, in
that piece of poetry which you was pleased to present unto
me, and I can but love and thank you for the same; and if
ever it should be in my power to be serviceable to you, in
any measure, your reasonable requests, shall be armed with
the obedience of,

"Your sincere friend and well-wisher,
"BENJAMIN BANNEKER.

"MRS. SUSANNA MASON.

"N.B. The above is mean writing, done with trembling hands.
B.B."

With the use of Mayer's Tables, Ferguson's Astronomy, and Leadbeater's Lunar Tables, Banneker had made wonderful progress in his astronomical investigations. He prepared his first almanac for publication in 1792. Mr. James McHenry became deeply interested in him, and, convinced of his talent in this direction, wrote a letter to the firm of Goddard & Angell, publishers of almanacs, in Baltimore. They became the sole publishers of Banneker's almanacs till the time of his death. In an editorial note in the first almanac, they say,--

"They feel gratified in the opportunity of presenting to the
public, through their press, what must be considered as an
extraordinary effort of genius; a complete and accurate
Ephemeris for the year 1792, calculated by a sable
descendant of Africa," etc.

And they further say,--

"That they flatter themselves that a philanthropic public,
in this enlightened era, will be induced to give their
patronage and support to this work, not only on account of
its intrinsic merits, (it having met the approbation of
several of the most distinguished astronomers of America,
particularly the celebrated Mr. Rittenhouse,) but from
similar motives to those which induced the editors to give
this calculation the preference,--the ardent desire of
drawing modest merit from obscurity, and controverting the
long-established illiberal prejudice against the blacks."

The title of his almanac is given below as a matter of historic interest.

"Benjamin Banneker's Pennsylvania, Delaware, Virginia, and
Maryland Almanac and Ephemeris, for the year of our Lord
1792, being Bissextile or leap year, and the sixteenth year
of American Independence, which commenced July 4, 1776;
containing the motions of the Sun and Moon, the true places
and aspects of the Planets, the rising and setting of the
Sun, and the rising, setting, and southing, place and age of
the Moon, &c. The Lunations, Conjunctions, Eclipses,
Judgment of the Weather, Festivals, and remarkable days."

He had evidently read Mr. Jefferson's Notes on Virginia; and touched by the humane sentiment there exhibited, as well as saddened by the doubt expressed respecting the intellect of the Negro, Banneker sent him a copy of his first almanac, accompanied by a letter which pleaded the cause of his race, and in itself, was a refutation of the charge that the Negro had no intellectual outcome.

"MARYLAND, BALTIMORE COUNTY, August 19, 1791.

"SIR,

"I am fully sensible of the greatness of the freedom I take
with you on the present occasion; a liberty which seemed
scarcely allowable, when I reflected on that distinguished
and dignified station in which you stand, and the almost
general prejudice which is so prevalent in the world against
those of my complexion.

"It is a truth too well attested, to need a proof here, that
we are a race of beings, who have long laboured under the
abuse and censure of the world; that we have long been
looked upon with an eye of contempt; and considered rather
as brutish than human, and scarcely capable of mental
endowments.

"I hope I may safely admit, in consequence of the report
which has reached me, that you are a man far less inflexible
in sentiments of this nature, than many others, that you are
measurably friendly and well disposed towards us; and that
you are willing to lend your aid and assistance for our
relief from those many distresses, and numerous calamities,
to which we are reduced.

"If this is founded in truth, I apprehend you will embrace
every opportunity to eradicate that train of absurd and
false ideas and opinions, which so generally prevail with
respect to us: and that your sentiments are concurrent with
mine, which are, that one universal Father hath given being
to us all; that He hath not only made us all of one flesh,
but that He hath also, without partiality, afforded us all
the same sensations, and endowed us all with the same
faculties; and that however variable we may be in society or
religion, however diversified in situation or in colour, we
are all of the same family, and stand in the same relation
to Him.

"If these are sentiments of which you are fully persuaded,
you cannot but acknowledge, that it is the indispensable
duty of those, who maintain for themselves the rights of
human nature, and who profess the obligations of
Christianity, to extend their powers and influence to the
relief of every part of the human race, from whatever burden
or oppression they may unjustly labour under: and this, I
apprehend, a full conviction of the truth and obligation of
these principles should lead all to.

"I have long been convinced, that if your love for
yourselves, and for those inestimable laws which preserved
to you the rights of human nature, was founded on sincerity
you could not but be solicitous, that every individual, of
whatever rank or distinction, might with you equally enjoy
the blessings thereof; neither could you rest satisfied
short of the most active effusion of your exertions, in
order to their promotion from any state of degradation, to
which the unjustifiable cruelty and barbarism of men may
have reduced them.

"I freely and cheerfully acknowledge, that I am of the
African race, and in that colour which is natural to them,
of the deepest dye; and it is under a sense of the most
profound gratitude to the Supreme Ruler of the Universe,
that I now confess to you, that I am not under that state of
tyrannical thraldom, and inhuman captivity, to which too
many of my brethren are doomed, but that I have abundantly
tasted of the fruition of those blessings, which proceed
from that free and unequalled liberty with which you are
favoured; and which I hope you will willingly allow you have
mercifully received, from the immediate hand of that Being
from whom proceedeth every good and perfect gift.

"Suffer me to recall to your mind that time, in which the
arms of the British crown were exerted, with every powerful
effort, in order to reduce you to a state of servitude: look
back, I entreat you, on the variety of dangers to which you
were exposed; reflect on that period in which every human
aid appeared unavailable, and in which even hope and
fortitude wore the aspect of inability to the conflict, and
you cannot but be led to a serious and grateful sense of
your miraculous and providential preservation; you cannot
but acknowledge, that the present freedom and tranquility
which you enjoy, you have mercifully received, and that it
is the peculiar blessing of heaven.

"This, Sir, was a time when you cleary saw into the
injustice of a state of Slavery, and in which you had just
apprehensions of the horrors of its condition. It was then
that your abhorrence thereof was so excited, that you
publicly held forth this true and invaluable doctrine, which
is worthy to be recorded and remembered in all succeeding
ages: 'We hold these truths to be self-evident, that all men
are created equal; that they are endowed by their Creator
with certain inalienable rights, and that among these are,
life, liberty, and the pursuit of happiness.'

"Here, was a time in which your tender feelings for
yourselves had engaged you thus to declare; you were then
impressed with proper ideas of the great violation of
liberty, and the free possession of those blessings, to
which you were entitled by nature; but, sir, how pitiable is
it to reflect, that although you were so fully convinced of
the benevolence of the Father of Mankind, and of his equal
and impartial distribution of these rights and privileges
which he hath conferred upon them, that you should at the
same time counteract his mercies, in detaining by fraud and
violence, so numerous a part of my brethren under groaning
captivity and cruel oppression, that you should at the same
time be found guilty of that most criminal act, which you
professedly detested in others, with respect to yourselves.

"Your knowledge of the situation of my brethren is too
extensive to need a recital here; neither shall I presume to
prescribe methods by which they may be relieved, otherwise
than by recommending to you and all others, to wean
yourselves from those narrow prejudices which you have
imbibed with respect to them, and as Job proposed to his
friends, 'put your soul in their soul's stead;' thus shall
your hearts be enlarged with kindness and benevolence
towards them; and thus shall you need neither the direction
of myself or others in what manner to proceed herein.

"And now, sir, although my sympathy and affection for my
brethren hath caused my enlargement thus far, I ardently
hope, that your candour and generosity will plead with you
in my behalf, when I state that it was not originally my
design; but having taken up my pen in order to present a
copy of an almanac which I have calculated for the
succeeding year, I was unexpectedly led thereto.

"This calculation is the production of my arduous study, in
my advanced stage of life: for having long had unbounded
desires to become acquainted with the secrets of nature, I
have had to gratify my curiosity herein through my own
assiduous application to astronomical study, in which I need
not recount to you the many difficulties and disadvantages
which I have had to encounter.

"And although I had almost declined to make my calculation
for the ensuing year, in consequence of the time which I had
allotted for it being taken up at the federal territory, by
the request of Mr. Andrew Ellicott, yet I industriously
applied myself thereto, and hope I have accomplished it with
correctness and accuracy. I have taken the liberty to direct
a copy to you, which I humbly request you will favourably
receive; and although you may have the opportunity of
perusing it after its publication, yet I desire to send it
to you in manuscript previous thereto, that thereby you
might not only have an earlier inspection, but that you
might also view it in my own handwriting.

"And now, sir, I shall conclude, and subscribe myself, with
the most profound respect,

"Your most obedient humble servant,
"BENJAMIN BANNEKER."

Mr. Jefferson, who was Secretary of State under President Washington, sent the great Negro the following courteous reply:--

"PHILADELPHIA, Aug. 30, 1791.

"SIR,--I thank you sincerely for your letter of the 19th
instant, and for the almanac it contained. Nobody wishes
more than I do to see such proofs as you exhibit, that
Nature has given to our black brethren talents equal to
those of the other colors of men, and that the appearance of
a want of them is owing only to the degraded condition of
their existence, both in Africa and America. I can add, with
truth, that no one wishes more ardently to see a good system
commenced for raising the condition, both of their body and
mind, to what it ought to be, as fast as the imbecility of
their present existence, and other circumstances which
cannot be neglected, will admit. I have taken the liberty of
sending your almanac to Monsieur de Condorcet, Secretary of
the Academy of Sciences, at Paris, and members of the
Philanthropic Society, because I considered it a document to
which your whole color had a right, for their justification
against the doubts which have been entertained of them,

"I am, with great esteem, sir,
"Your most obedient servant,
"THO. JEFFERSON.

"MR. BENJAMIN BANNEKER, near Ellicott's

Lower Mills, Baltimore county."[614]

The only time Banneker was ever absent from his home any distance was when "the Commissioners to run the lines of the District of Columbia"--then known as the "Federal Territory"--invited him to accompany them upon their mission. Mr. Norris says:--

"Banneker's deportment throughout the whole of this
engagement, secured their respect, and there is good
authority for believing, that his endowments led the
commissioners to overlook the color of his skin, to converse
with him freely, and enjoy the clearness and originality of
his remarks on various subjects. It is a fact, that they
honored him with an invitation to a daily seat at their
table; but this, with his usual modesty, he declined. They
then ordered a side table laid for him, in the same
apartment with themselves. On his return, he called to give
an account of his engagements, at the house of one of his
friends. He arrived on horseback, dressed in his usual
costume;--full suit of drab cloth, surmounted by a broad
brimmed beaver hat. He seemed to have been re-animated by
the presence of the eminent men with whom he had mingled in
the District, and gave a full account of their proceedings."

His habits of study were rather peculiar. At nightfall, wrapped in a great cloak, he would lie prostrate upon the ground, where he spent the night in contemplation of the heavenly bodies. At sunrise he would retire to his dwelling, where he spent a portion of the day in repose. But as he seemed to require less sleep than most people, he employed the hours of the afternoons in the cultivation of his garden, trimming of fruit-trees, or in observing the habits and flight of his bees. When his service and attention were not required out-doors, he busied himself with his books, papers, and mathematical instruments, at a large oval table in his house. The situation of Banneker's dwelling was one which would be admired by every lover of nature, and furnished a fine field for the observation of celestial phenomena. It was about half a mile from the Patapsco River, and commanded a prospect of the near and distant hills upon its banks, which have been so justly celebrated for their picturesque beauty. A never-failing spring issued from beneath a large golden-willow tree in the midst of his orchard.[615] The whole situation was charming, inspiring, and no doubt helped him in the solution of difficult problems.

There is no reliable data to enlighten us as to the day of his death; but it is the opinion of those who lived near him, and their descendants, that he died in the fall of 1804. It was a bright, beautiful day, and feeling unwell he walked out on the hills to enjoy the sunlight and air. During his walk he came across a neighbor, to whom he complained of being sick. They both returned to his house, where, after lying down upon his couch, he became speechless, and died peacefully. During a previous sickness he had charged his sisters, Minta Black and Molly Morten, that, so soon as he was dead, all the books, instruments, etc., which Mr. Ellicott had loaned him, should be taken back to the benevolent lender; and, as a token of his gratitude, all his manuscripts containing all his almanacs, his observations and writings on various subjects, his letter to Thomas Jefferson, and that gentleman's reply, etc., were given to Mr. Ellicott.[616] On the day of his death, faithful to the instructions of their brother, Banneker's sisters had all the articles moved to Mr. Ellicott's house; and their arrival was the first sad news of the astronomer's death. To the promptness of these girls in carrying out his orders is the gratitude of the friends of science due for the preservation of the results of Banneker's labors. During the performance of the last sad rites at the grave, two days after his death, his house was discovered to be on fire. It burnt so rapidly that it was impossible to save any thing: so his clock and other personal property perished in the flames. He had given to one of his sisters a feather-bed, upon which he had slept for many years; and she, fortunately and thoughtfully, removed it when he died, and prized it as the only memorial of her distinguished brother. Some years after, she had occasion to open the bed, when she discovered a purse of money--another illustration of his careful habits and frugality.

Benjamin Banneker was known favorably on two continents, and at the time of his death was the most intelligent and distinguished Negro in the United States.

FULLER THE MATHEMATICIAN.

One of the standing arguments against the Negro was, that he lacked the faculty of solving mathematical problems. This charge was made without a disposition to allow him an opportunity to submit himself to a proper test. It was equivalent to putting out a man's eyes, and then asserting boldly that he cannot see; of manacling his ankles, and charging him with the inability to run. But notwithstanding all the prohibitions against instructing the Negro, and his far remove from intellectual stimulants, the subject to whom attention is now called had within his own untutored intellect the elements of a great mathematician.

Thomas Fuller, familiarly known as the Virginia Calculator, was a native of Africa. At the age of fourteen he was stolen, and sold into slavery in Virginia, where he found himself the property of a planter residing about four miles from Alexandria. He did not understand the art of reading or writing, but by a marvellous faculty was able to perform the most difficult calculations. Dr. Benjamin Rush of Philadelphia, Penn., in a letter addressed to a gentleman residing in Manchester, Eng., says that hearing of the phenomenal mathematical powers of "Negro Tom," he, in company with other gentlemen passing through Virginia, sent for him. One of the gentlemen asked him how many seconds a man of seventy years, some odd months, weeks, and days, had lived, he gave the exact number in a minute and a half. The gentleman took a pen, and after some figuring told Tom he must be mistaken, as the number was too great." 'Top, massa!" exclaimed Tom, "you hab left out de leap-years!" And sure enough, on including the leap-years in the calculation, the number given by Tom was correct.

"He was visited by William Hartshorn and Samuel Coates,"
says Mr. Needles, "of this city (Philadelphia), and gave
correct answers to all their questions such as, How many
seconds there are in a year and a half? In two minutes he
answered 47,304,000. How many seconds in seventy years,
seventeen days, twelve hours? In one minute and a half,
2,110,500,800.[617]

That he was a prodigy, no one will question.[618] He was the wonder of the age. The following appeared in several newspapers at the time of his death:--

"DIED,--Negro Tom, the famous African calculator, aged 80
years. He was the property of Mrs. Elizabeth Cox, of
Alexandria. Tom was a very black man. He was brought to this
country at the age of fourteen, and was sold as a slave with
many of his unfortunate countrymen. This man was a prodigy.
Though he could neither read nor write, he had perfectly
acquired the use of enumeration. He could give the number of
months, days, weeks, hours, minutes, and seconds, for any
period of time that a person chose to mention, allowing in
his calculations for all the leap years that happened in the
time. He would give the number of poles, yards, feet,
inches, and barley-corns in a given distance--say, the
diameter of the earth's orbit--and in every calculation he
would produce the true answer in less time than ninety-nine
out of a hundred men would take with their pens. And what
was, perhaps, more extraordinary, though interrupted in the
progress of his calculations, and engaged in discourse upon
any other subject, his operations were not thereby in the
least deranged; he would go on where he left off, and could
give any and all of the stages through which the calculation
had passed.

"Thus died Negro Tom, this untaught arithmetician, this
untutored scholar. Had his opportunities of improvement been
equal to those of thousands of his fellow-men, neither the
Royal Society of London, the Academy of Science at Paris,
nor even a Newton himself need have been ashamed to
acknowledge him a brother in science."[619]

DERHAM THE PHYSICIAN.

Through all time the science of medicine has been regarded as ranking among the most intricate and delicate pursuits man could follow. Our Saviour was called "the Great Physician," and St. Luke "the beloved physician." No profession brings a man so near to humanity, and no other class of men have a higher social standing than those who are consecrated to the "art of healing." Such a position demands of a man not only profound research in the field of medicine, but the rarest intellectual and social gifts and accomplishments. For a Negro to gain such a position in the nineteenth century would require merit of unusual order. But in the eighteenth century, when slavery had cast its long, dark shadows over the entire life of the nation, for a Negro, born and reared a slave, to obtain fame in medicine second to none on the continent, was an achievement that justly challenged the admiration of the civilized world.

Dr. James Derham was born a slave in Philadelphia in 1762. His master was a physician. James was taught to read and write, and early rendered valuable assistance to his master in compounding medicines. Endowed with more than average intelligence, he took a great liking to the science of medicine, and absorbed all the information that came within his observation. On the death of his master he was sold to the surgeon of the Sixteenth British Regiment, at that time stationed in Philadelphia. At the close of the war he was sold to Dr. Robert Dove of New Orleans, a humane and intelligent man, who employed him as his assistant in a large business. He grew in a knowledge of his profession every day, was prompt and faithful in the discharge of the trusts reposed in him, and thereby gained the confidence of his master. Dr. Dove was so much pleased with him, that he offered him his freedom upon very easy terms, requiring only two or three years' service. At the end of the time designated, Dr. Derham entered into the practice of medicine upon his own account. He acquired the English, French, and Spanish languages so as to speak them fluently, and built up a practice in a short time worth three thousand dollars a year.[620] He married, and attached himself to the Episcopal Church, in 1788, and at twenty-six years of age was regarded as one of the most eminent physicians in New Orleans.

Dr. Rush of Philadelphia, in "The American Museum" for January, 1789, gave an interesting account of this distinguished "Negro physician." Says Dr. Rush,--

"I have conversed with him upon most of the acute and
epidemic diseases of the country where he lives. I expected
to have suggested some new medicines to him, but he
suggested many more to me. He is very modest and engaging in
his manners. He speaks French fluently, and has some
knowledge of the Spanish."[621]

Phillis Wheatley has been mentioned already. So, in the midst of darkness and oppression, the Negro race in America, without the use of the Christian church, schoolhouse, or printing-press, produced a _poetess_, an _astronomer_, a _mathematician_, and a _physician_, who, had they been white, would have received monuments and grateful memorials at the hands of their countrymen. But even their color cannot rob them of the immortality their genius earned.
