New England for years how he did so successfully. Eliot also inquired how the farmer profited from it. He explained the efforts of the Society for the Encouragement of Arts, Manufactures and Commerce to establish silk-making in Connecticut, and speculated on which land in Connecticut (north or south) is better suited to the growth of silk. The seventh essay was not part of the Essays Upon Field Husbandry, but it concerned a new way to manufacture iron from a substance found in New England. This essay was entitled An Essay On The Invention or Art of Making Very Good, If Not The Best Iron, From Black Sea Sand. Eliot recounted how he experimented with "black sea sand" for use in iron-making. In 1744 Eliot's uncles, Aaron Eliot and Ichabod Miller, succeeded in making more than a half-ton of steel at the furnace in Sansbury. Since the only place to get steel-making materials was New York, there was a need to find sources closer to home. Jared revealed that he was part of a group of investigators who secured an ore bed at Sansbury (by a patent grant from the Great Assembly) to find something to make into iron. This essay concerned the experiments and findings from using black sea sand to make iron. Eliot's essays were not widely accepted in New England until the 19th century. However, some contemporaries recognized his efforts to improve farming practices. Among those he inspired were Benjamin Franklin and John Adams. Both men felt that Eliot's essays were an important contribution to the development of the colonies. These essays supported colonial interests and imperial designs involving communication with the other colonies and Britain. Eliot also attempted trade with other countries, but was unsuccessful before his death on April 22, 1763. In 1765 the Stamp Act was invoked by the British, and communication between the colonies and Britain became impossible. Legacy Two years before his death, Eliot made his will. It stated, “I will and bequeath to the President and Fellows of Yale College, in New Haven, ten pounds of lawful money, the interest of which sum shall be applied to the use of the library, in buying books from time to time, according to their best skill”, this was the first Yale college library fund. He felt it was important to return something to the place that made him into the well-educated individual he was.
