AN AIR-SHIP OF 1709.
In the network above the figure were to be set coral-agates, supposed to possess such magnetic powers as to keep the craft aloft. From Valentini, “Museum Museorum,” Pt. III, Franckfurt am Mayn, 1714, p.35. Author’s library.

About the middle of the past century, the demand for agate amulets was so great in the Soudan that the extensive agate-cutting establishments at Idar and Oberstein in Germany were almost exclusively busied with filling orders for this trade. Brown or black agates having a white ring in the centre were chiefly used for the fabrication of these amulets, the white ring being regarded as a symbol of the eye. Hence the amulets were supposed to neutralize the power of the Evil Eye, or else to be emblematic of the watchfulness of a guardian spirit. The demand for these amulets has fallen off greatly, but when it was at its height single firms exported them to the value of 40,000 thalers ($30,000) annually, the total export amounting to hundreds of thousands of thalers. Even at present a considerable trade in these objects is still carried on. That there is a fashion in amulets is shown by the fact that, while red, white, and green amulets are in demand on the west coast of Africa, only white stones are favored for this use in Northern Africa.
