Nothing was done until the reign of Queen Anne, when a petition was presented to the Legislature on the 25th of May, 1714, by "several captains of Her Majesty's ships, merchants in London, and commanders of merchantmen, in behalf of themselves, and of all others concerned in the navigation of Great Britain," setting forth the importance of the accurate discovery of the longitude, and the inconvenience and danger to which ships were subjected from the want of some suitable method of discovering it. The petition was referred to a committee, which took evidence on the subject. It appears that Sir Isaac Newton, with his extraordinary sagacity, hit the mark in his report. "One is," he said, "by a watch to keep time exactly; but, by reason of the motion of a ship, and the variation of heat and cold, wet and dry, and the difference of gravity in different latitudes, such a watch hath not yet been made."
An Act was however passed in the Session of 1714, offering a very large public reward to inventors: 10,000L. to any one who should discover a method of determining the longitude to one degree of a great circle, or 60 geographical miles; 15,000L. if it determined the same to two-thirds of that distance, or 40 geographical miles; and 20,000L. if it determined the same to one-half of the same distance, or 30 geographical miles. Commissioners were appointed by the same Act, who were instructed that "one moiety or half part of such reward shall be due and paid when the said commissioners, or the major part of them, do agree that any such method extends to the security of ships within 80 geographical miles of the shore, which are places of the greatest danger; and the other moiety or half part when a ship, by the appointment of the said commissioners, or the major part of them, shall actually sail over the ocean, from Great Britain to any such port in the West Indies as those commissioners, or the major part of them, shall choose or nominate for the experiment, without losing the longitude beyond the limits before mentioned."
The terms of this offer indicate how great must have been the risk and inconvenience which it was desired to remedy. Indeed, it is almost inconceivable that a reward so great could be held out for a method which would merely afford security within eighty geographical miles!
This splendid reward for a method of discovering the longitude was offered to the world—to inventors and scientific men of all countries—without restriction of race, or nation, or language. As might naturally be expected, the prospect of obtaining it stimulated many ingenious men to make suggestions and contrive experiments; but for many years the successful construction of a marine time-keeper seemed almost hopeless. At length, to the surprise of every one, the prize was won by a village carpenter—a person of no school, or university, or college whatever.
Even so distinguished an artist and philosopher as Sir Christopher Wren was engaged, as late in his life as the year 1720, in attempting to solve this important problem. As has been observed, in the memoir of him contained in the 'Biographia Britannica,'[3] "This noble invention, like some others of the most useful ones to human life, seems to be reserved for the peculiar glory of an ordinary mechanic, who, by indefatigable industry, under the guidance of no ordinary sagacity, hath seemingly at last surmounted all difficulties, and brought it to a most unexpected degree of perfection." Where learning and science failed, natural genius seems to have triumphed.
The truth is, that the great mechanic, like the great poet, is born, not made; and John Harrison, the winner of the famous prize, was a born mechanic. He did not, however, accomplish his object without the exercise of the greatest skill, patience, and perseverance. His efforts were long, laborious, and sometimes apparently hopeless. Indeed, his life, so far as we can ascertain the facts, affords one of the finest examples of difficulties encountered and triumphantly overcome, and of undaunted perseverance eventually crowned by success, which is to be found in the whole range of biography.
No complete narrative of Harrison's career was ever written. Only a short notice of him appears in the 'Biographia Britannica,' published in 1766, during his lifetime'—the facts of which were obtained from himself. A few notices of him appear in the 'Annual Register,' also published during his lifetime. The final notice appeared in the volume published in 1777, the year after his death. No Life of him has since appeared. Had he been a destructive hero, and fought battles by land or sea, we should have had biographies of him without end. But he pursued a more peaceful and industrious course. His discovery conferred an incalculable advantage on navigation, and enabled innumerable lives to be saved at sea; it also added to the domains of science by its more exact measurement of time. But his memory has been suffered to pass silently away, without any record being left for the benefit and advantage of those who have succeeded him. The following memoir includes nearly all that is known of the life and labours of John Harrison.
He was born at Foulby, in the parish of Wragby, near Pontefract, Yorkshire, in March, 1693. His father, Henry Harrison, was carpenter and joiner to Sir Rowland Winn, owner of the Nostell Priory estate. The present house was built by the baronet on the site of the ancient priory. Henry Harrison was a sort of retainer of the family, and long continued in their Service.
Little is known of the boy's education. It was certainly of a very inferior description. Like George Stephenson, Harrison always had a great difficulty in making himself understood, either by speech or writing. Indeed, every board-school boy now receives a better education than John Harrison did a hundred and eighty years ago. But education does not altogether come by reading and writing. The boy was possessed of vigorous natural abilities. He was especially attracted by every machine that moved upon wheels. The boy was 'father to the man.' When six years old, and lying sick of small-pox, a going watch was placed upon his pillow, which afforded him infinite delight.
When seven years old he was taken by his father to Barrow, near Barton-on-Humber, where Sir Rowland Winn had another residence and estate. Henry Harrison was still acting as the baronet's carpenter and joiner. In course of time young Harrison joined his father in the workshop, and proved of great use to him. His opportunities for acquiring knowledge were still very few, but he applied his powers of observation and his workmanship upon the things which were nearest him. He worked in wood, and to wood he first turned his attention.
