Jet

Jet, a variety of lignite, resembling cannel coal, but harder, of deeper black, and of more brilliant lustre. It is found in detached pieces in tertiary clays along the coast of Yorkshire, England, and in various places on the continent of Europe. From its susceptibility of taking a fine polish and its intense blackness, it has been largely used for mourning articles of ornament, as buttons, crosses, and ear rings.

Jethro Tull

Jethro Tull, an English agriculturist, born about 1680, died in January, 1740. He owned an estate near Hungerford, on the borders of Oxfordshire and Berkshire, and observing the advantage of cultivation of plants in rows, and of stirring and pulverizing the soil between them, he introduced this system of cultivating the soil. But he adopted the erroneous principle that manure was not essential, as finely pulverized earth and moisture were sufficient for the growth of plants. This ruined him, and brought discredit upon his system. He published a treatise on his new mode of cultivation (1731), and detached essays, which were collected in 1751, and republished by William Cobbett in 1822. (See Agriculture, vol. i., p. 203).
