"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:
