or religion, however diversified in situation or color, we are all of the same family, and all stand in the same relation to Him. Now, sir, if this is founded in truth, I apprehend you will readily embrace every opportunity to eradicate the absurd and false ideas and opinions which so generally prevail with respect to us.

"Suffer me, sir, to recall to your mind, that when the tyranny of the British crown was exerted to reduce you to servitude, your abhorrence thereof was so excited, that you publicly held forth this true and invaluable doctrine, worthy to be recorded and remembered in all succeeding ages: 'We hold these truths to be self-evident, that all men are created equal, and that they are endowed by their Creator with certain inalienable rights; that among these are life, liberty, and the pursuit of happiness.'

"Your tender feelings for yourselves engaged you thus to declare. You were then impressed with proper ideas of the great value of Liberty, and the free possession of those blessings to which you were entitled by nature. But, sir, how pitiable it is 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 those rights and privileges which He had 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 detested in others with respect to yourselves.

"Sir, I freely and most cheerfully acknowledge that I am of the African race; and in that color which is natural to them I am of the deepest dye. But, with a sense of most profound gratitude to the Supreme Ruler of the universe, I confess that I am not under that state of tyrannical thraldom and inhuman captivity to which so many of my brethren are doomed. I have abundantly tasted of those blessings which proceed from that free and unequalled liberty with which you are favored.

"Sir, I suppose your knowledge of the situation of my brethren is too extensive for it 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 others to wean yourselves from those narrow prejudices you have imbibed with respect to them, and to do as Job proposed to his friends,—'Put your souls in their souls' stead.' Thus shall your hearts be enlarged with kindness and benevolence toward them, and you will need neither the direction of myself nor others in what manner to proceed.

"I took up my pen to direct to you, as a present, a copy of an Almanac I have calculated for the succeeding year. I ardently hope that your candor and generosity will plead with you in my behalf. Sympathy and affection for my brethren has caused my enlargement thus far; it was not originally my design.

"The Almanac is the production of my arduous study. I have long had unbounded desires to become acquainted with the secrets of Nature, and 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 I have had to encounter. I conclude by subscribing myself, with the most profound respect, your most humble servant,

"B. Banneker."

To this letter Jefferson made the following reply:—

"Sir,—I thank you sincerely for your letter, 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 Condorcet, Secretary of the Academy of Sciences at Paris, and to 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,

"Thomas Jefferson."

In 1803, Mr. Jefferson invited the astronomer to visit him at Monticello, but the increasing infirmities of age made it imprudent to undertake the journey. His Almanacs sold well for ten years, and the income, added to his annuity, gave him a very comfortable support; and what was a still greater satisfaction to him was the consciousness of doing something to help the cause of his oppressed people, by proving to the world that Nature had endowed them with good capacities.

After 1802 he found himself too old to calculate any more Almanacs, but as long as he lived he continued to be deeply interested in his various studies.

He was well informed on many other subjects besides arithmetic and astronomy. He was a great reader of history; and he kept a Journal, which shows that he was a close observer of the vegetable world, of the habits of insects, and of the operations of Nature in general. That his busy mind drew inferences from what he observed is evident from the following entry in his Journal:—

"Standing at my door to-day, I heard the discharge of a gun, and in four or five seconds of time the small shots came rattling about me, which plainly demonstrates that the velocity of sound is greater than that of a common bullet."

After the Constitution of the United States was adopted, in 1789, commissioners were appointed to determine the boundaries of the District of Columbia. They invited Banneker to be present and assist them in running the lines; and he was treated by them with as much respect as if he had been of their own color. His Almanacs were much praised by scientific men, and they often visited him in his humble little cabin. But these attentions never made him pert and vain. He rejoiced in his abilities and acquisitions, because he thought they might help to raise the condition of his oppressed brethren; but he always remained modest and unobtrusive in his manners.

He died in 1804, in the seventy-second year of his age. His friend, Mr. Benjamin H. Ellicott, collected various facts concerning him, which have been published. In a letter on this subject, Mr. Ellicott says: "During the whole of his long life he lived respectably, and was much esteemed by all who became acquainted with him; more especially by those who could fully appreciate his genius and the extent of his acquirements. His mode of life was extremely regular and retired. Having never married, he lived alone, cooking his own victuals and washing his own clothes. He was scarcely ever absent from home, yet there was nothing misanthropic in his character. A gentleman who knew him speaks of him thus: 'I recollect him well. He was a brave-looking, pleasant man, with something very noble in his appearance. His mind was evidently much engrossed in his calculations, but he was glad to receive the visits we often paid him.' Another writes: 'When I was a boy, I became very much interested in him. His manners were those of a perfect gentleman. He was kind, generous, hospitable, humane, dignified, and pleasing. He abounded in information on all the various subjects and incidents of the day, was very modest and unassuming, and
