      Curiosities of Human Nature

      ZERAH COLBURN

      Among the intellectual prodigies which sometimes appear to excite the wonder and astonishment of mankind, Zerah Colburn was certainly one of the most remarkable. He was born at Cabot, Vermont, Sept. 1st, 1804. He was the sixth child of his parents, who were persons in low circumstances and of little education. He was regarded as the most backward of the children till he was about six years old, when he suddenly attracted attention by the display of his astonishing powers.

      In August, 1810, when his father, Abia Colburn, was one day employed at a joiner's work-bench, Zerah was on the floor, playing among the chips; suddenly, he began to say to himself, – 5 times 7 are 35 – 6 times 8 are 48, &c. His father's attention was immediately arrested by hearing this, so unexpected in a child so young, and who had hitherto possessed no advantages, except perhaps six weeks' attendance at the district school, that summer. He therefore left his work, and turning to the child, began to examine him in the multiplication table. He thought it possible that Zerah had learnt this from the other boys; but finding him perfect in the table, his attention was more deeply fixed, and he asked the product of 13×97, to which 1261 was instantly given as the answer. He now concluded that something unusual had actually taken place; indeed, he has often said he should not have been more surprised if some one had risen up out of the earth and stood erect before him.

      It was not long before a neighbor rode up, and stopping at the house, was informed of the singular occurrence. He desired to be a witness of the fact. Zerah was called, and the result of the examination astonished every one present. The strange phenomenon was now rapidly spread throughout the town. Though many were inclined to doubt the correctness of the reports they heard, a personal examination attested their truth. Thus the story originated, which within the short space of a year found its way not only through the United States, but also reached Europe, and extorted expressions of wonder from foreign journals of literature and science in England, France and other countries.

      Very soon after the discovery of his remarkable powers, many gentlemen, at that time possessing influence and public confidence throughout the state, being made acquainted with the circumstances, were desirous of having such a course adopted as might most directly lead to a full development of Zerah's talents, and their application to purposes of general utility. Accordingly, it was proposed that Mr. Colburn should carry his son to Danville, to be present during the session of the court. This was done, and the boy was very generally seen and questioned by the judges, members of the bar, and others.

      The legislature of Vermont being about to convene at Montpelier, Mr. Colburn was advised to visit that place with his son, which they did in October. Here large numbers had an opportunity of witnessing his calculating powers, and the conclusion was general that such a thing had never been known before. Many questions, which were out of the common limits of arithmetic, were proposed, with a view to puzzle the child, but he answered them correctly; as, for instance, – which is the most, twice twenty-five, or twice five and twenty? Ans. Twice twenty-five. Which is the most, six dozen dozen, or half a dozen dozen? Ans. Six dozen dozen. Somebody asked him how many black beans would make five white ones. Ans. Five, if you skin them! Thus it appeared that the boy could not only compute and combine numbers readily, but that he also possessed a quickness of thought, somewhat uncommon among children, as to other things.

      Soon after this, Mr. Colburn took his son to other large towns, and at last to Boston. Here the boy excited the most extraordinary sensation, and several gentlemen of the highest standing proposed to undertake his education. The terms, though very liberal, were not equal to the high-raised expectations of the father. The offer was therefore refused, and Mr. Colburn proceeded to the southern cities, exhibiting his son in public, his performances everywhere exciting the utmost wonder.

      The author of these pages had an opportunity of seeing Zerah Colburn, at this period. He was a lively, active boy, of light complexion, his head being rather larger than that of boys generally at his age. He was then six years old, and had the manners common to children of his age. He was playful, even while performing his calculations. The quickness and precision with which he gave answers to arithmetical questions was amazing. Among those proposed to him at Boston, in the autumn of the year 1810, were the following:

      What is the number of seconds in 2000 years? The answer, 63,072,000,000, was readily and accurately given. Another question was this: Allowing that a clock strikes 156 times in a day, how many times will it strike in 2000 years? The child promptly replied, 113,800,000 times.

      What is the product of 12,225, multiplied by 1,223? Ans. 14,951,175. What is the square of 1,449? Ans. 2,099,601. Suppose I have a corn-field, in which are seven acres, having seventeen rows to each acre, sixty-four hills to each row, eight ears on a hill, and one hundred and fifty kernels on an ear; how many kernels in the corn-field? Ans. 9,139,200.

      It will be recollected that the child who answered these questions was but six years old; that he had then had no instruction whatever in arithmetic; that he could neither read nor write, and that he performed these immense calculations by mental processes, wholly his own. His answers were usually given, and the calculations performed, while engaged in his sports, and the longest process seemed hardly to divert his mind from his amusements. His answers were often made almost as soon as the question was proposed, and in most cases before the process could be performed on paper.

      His faculty for calculation seemed to increase, and as he became acquainted with arithmetical terms, his performances were still more remarkable. In June, 1811, he was asked the following question: If the distance between Concord and Boston be sixty-five miles, how many steps must I take in going this distance, supposing each step to be three feet? The answer, 114,400 steps, was given in ten seconds. He was asked how many days and hours had elapsed since the Christian era commenced. In twenty seconds he replied, 661,015 days, 15,864,360 hours.

      Questions still more difficult were answered with similar promptitude. What sum multiplied by itself will produce 998,001? In less than four seconds he replied 999. How many hours in thirty-eight years, two months, and seven days? The answer, 334,488, was given in six seconds.

      These extraordinary performances, witnessed by thousands of people, and among them persons of the highest standing, were soon reported in the papers, and attracted scarcely less attention in Europe than in this country. In England, particularly, great curiosity was expressed, and the plan of taking young Colburn thither was suggested. After some deliberation, this project was resolved upon; and in the spring of 1812, the father and son embarked at Boston for Liverpool, where they landed on the 11th of May. They proceeded to London, and taking rooms at Spring Gardens, commenced their exhibition.

      Great numbers came to witness the performances of the boy, among whom Zerah, in his Life, enumerates the dukes of Gloucester and Cumberland, Lord Ashburton, Sir James Mackintosh, Sir Humphrey Davy, and the Princess Charlotte. The latter, attended by her tutor, the bishop of Salisbury, remained a full hour, and asked a number of questions. Among the rest was this: What is the square of 4001? The answer, 16,008,001, was immediately given. The duke of Cambridge asked the number of seconds in the time elapsed since the commencement of the Christian era, 1813 years, 7 months, 27 days. The answer was correctly given, 57,234,384,000.

      An extraordinary interest was excited in London in respect to this remarkable youth, and schemes for giving him an education suited to his turn of mind were suggested. At a meeting of several distinguished gentlemen, to mature some plan of this sort, various questions were proposed to the child. He multiplied the number eight by itself, and each product by itself, till he had raised it to the sixteenth power, giving, as the almost inconceivable result, 281,474,976,710,656. He was asked the square root of 106,929, and before the number could be written down, he answered 327. He was then requested to name the cube root of 268,336,125, and with equal facility and promptness he replied, 645.

      A likeness of the young prodigy, drawn by Hull and engraved by Meyer, was now published, and sold at a guinea each. Many were sold, and a considerable profit was realized. Another scheme was now started, – a memoir of the child, – and among the committee to superintend its publication, were Sir James Mackintosh, Sir Humphrey Davy and Basil Montague. Several hundred subscribers were obtained, but, though many paid in advance, for some reason or other the work was never
