the Sill floor of the 1869 level, we have
Deen engaged in timbering and have
been cutting out for that purpose
ana have extracted a few tons

drlft, No. 3, started from the west cross
cut Is feet below the sill floor of this level
ana IA feet under south drift . has
been extended 81 feet. The first feet is
IN ore OF low grade and the remaining 10
feet IN solid ore of a steadily improving
quality. The average assay value of which
(per car sampies) was about $50 per ton.
Inc lace OF this south drift is ore of high
grade, which will average over 500 mr.
