This was indeed a wonderful gift,--and from a stranger! Difficulties at once presented themselves. How could the property be used "for the increase and diffusion of knowledge among men"? "For ten years," says Garfield, "Congress wrestled with those nine words of Smithson, and could not handle them. Some political philosophers of that period held that we had no constitutional authority to accept the gift at all, and proposed to send it back to England. Every conceivable proposition was made." John Quincy Adams desired a great astronomical observatory. One person wished an agricultural school; another, a college for women; another, that the funds should be devoted to meteorological observations all over the Union. Finally, a board of regents was appointed, with power to choose a suitable person as secretary. He must be a learned man, a wise financier, with good judgment and pleasant manners. Professor Henry fulfilled all the conditions. He was admired for his learning; in finance he was wise, as thirty years have proved, the institute with its endowment now being valued at one and a half million dollars; his kindly manner made him accessible, willing to listen to any one who hoped or believed he had discovered something in the line of knowledge. A man who can be harsh or cold to an ignorant person, or indeed to anybody, does not deserve to hold any public position. With natural quickness of temper in early life, he had gained remarkable self-control. Like Baron Cuvier, he had no tolerance for sarcasm or "practical jokes." Henry was unanimously chosen, entering upon his duties December 3, 1846. He had a definite plan of the work which ought to be done, and "after due deliberation it received the almost unanimous approval of the scientific world." He believed that the money should be used in original scientific work; by helping men to publish the results of such work; to aid in varied explorations; to send scientific publications all over the world. The institution is now the principal agent of scientific and literary communication between the old world and the new. The number of foreign institutions and correspondents receiving the Smithsonian publications exceeds two thousand, scattered from New Zealand and India to Yokohama, in Japan, and Cape Town, in Southern Africa. The weight of matter sent abroad for ten years, ending 1877, was ninety-nine thousand pounds. Among the first subjects taken up by the institution for investigation was that of American archæology, an attempt to ascertain the industrial, social, and intellectual character of the earliest races on our continent. The first publication of "Smithsonian Contributions" was a work on the mounds and earthworks found in the Mississippi valley, a most fascinating study.
