<br />10,089 Pt., same being the datum, or zero point,
<br />The ore bodies oP this property are developed through three

<br />equipped vgith 6 in, air line, and 30 ib, track, and lighted with
<br />eleotrioity, Mules are. used in hauling trains of ore to No.l ore
<br />house, excepting No,2 shaft. All supplies, timber and men For I
