astronomical calculations; and he became so exact, that he pointed out two mistakes made by celebrated astronomers in Europe.

In order to pursue his favorite studies without interruption, he sold the land which his parents had left him, and bought an annuity with the money, on which he lived in the little cabin where he was born. He was so temperate and frugal, that he needed very little to support him; and when it was necessary to have more than his annuity, he could always earn something by going out to work. But, as he was no longer seen in the fields late and early, his ignorant white neighbors began to talk against him. They peeped into his cabin and saw him asleep in the daytime. They did not know that he had been awake all night watching the stars, and ciphering out his calculations. In fact, they did not know that the planets moved at all; and if he had told them that he could calculate their movements exactly, they would only have laughed at him. I suppose they felt some ill-will toward him because he was black, and yet knew so much more than they did; and perhaps it excited their envy that the Ellicott family and other educated gentlemen liked to[17] go to his cabin and talk with him about his studies and observations.

But Banneker was wise enough not to enter into any quarrels because they called him a lazy, good-for-nothing fellow. He endeavored to live in such a way that they could not help respecting him. He was always kind and generous, ready to oblige everybody, and not at all inclined to boast of his superiority.

When he was fifty-nine years old, he made an Almanac. It is a very difficult job to calculate all about the changes of the moon, and the rising and ebbing of the tides, and at what time the sun will rise and set every day, all the year round; and it was a much more difficult task then than it is now; because now there is a great improvement in astronomical books and instruments. But notwithstanding Banneker's limited means and scanty education, he made an excellent Almanac. It was published by Goddard and Angell of Baltimore. In a Preface, they say: "We feel gratified to have an opportunity of presenting to the public, through our press, what must be considered an extraordinary effort of genius,—a complete and accurate Ephemeris[2] for the year 1792, calculated by a sable son of Africa. It has met the approbation of several of the most distinguished astronomers of America; and we hope a philanthropic public will give their support to the work, not only on account of its intrinsic
