Other lots gave like results,and these are probably average examples. The actual output is hard to estimate. The onl} data are the exportfigures, and these are far below the reality, as the amount thus indi-cated for both diamonds and carbons is less than the value of the latteralone. This shows that large quantities must leave the country with-out paying dut}^ All the shipments are to Paris and London. The diamonds are exported uncut, though there are several cuttingestablishments in the diamond region arid one in Bahia. But there isat present little demand for cut stones in the countr}^ a condition dif-ferent from that reported in Minas Geraes by Mr. Dawson in 1899,but perhaps due to financial depression, as Mr. Furniss believes.
