must have been lost in the stamping box which was merely a planked structure round the 
stamp-head; and as no more trials could then be made on this reef, an average result has 
not been entered in the table. 
The quartz of the Monarch Reef is generally a milky-white coarse-textured rather glassy- 
lustred compact rock. At times it is stained brown or red along the fractures, and shows 
thin sheets and seams of brown iron rust. Flakes of bright golden colored mica are 
frequent; and there are rare seams of greenish talc and chlorite. White iron-pyrites 
occurs at rare intervals. The quartz is rudely laminated with the lie of the reef, and spurs 
of talcose schist are frequently running into the body of the lode. The casing is partly of 
talcose schist, with frequent laminae of pyrolusite. This description applies to so much as 
is exposed in the drive or cross-cut. 
The foot wall and leaders of this great reef have been extensively worked on the slope 
of the ridge overlooking the old Dayvallah valley in Mr. Hughes’ clearing, and in the 
valley itself. 
Korurnbar Reef and others. —Between the Hamlin and Skull Reef, there are at least 
five lodes, but they are only traceable at intervals to the district road. One, called after the 
native miners who pointed it out, gave another set of curious returns, which will illustrate 
the faulty condition of the extemporized crushing apparatus with which work had to be done. 
Seven pounds of stone from the Korurnbar Reef were liand-pounded and gave 12'40 grains 
of good yellow gold; and a further crushing of the tailings of white iron-pvrites, of which 
there was a large quantity, added -40 grains to this ; being in the proportion of 8 oz. 10 dwt. 
16 grains to the ton. One hundred and sixty pounds of this stone were then pounded, and 
all but 10 lbs. crushed and passed over the cradle, when gold at the rate of half a penny¬ 
weight to the ton was got. But from the 10 lbs. remaining which was hand-crushed there 
was gold at the rate ot 71 dwts. to the ton. In the meantime, another sample of 4 lbs. of 
stone was brought in from a new reef (Hamslade Waterfall) which gave 7 grains of gold, 
I then went to this reef with the men and quarried out about 70 lbs. of stone which was 
divided for separate trial by wet crushing and by hand work, when the following outturn 
appeared:— 
30 lbs. hand work ... ... ... 5-3 grains of gold. 
40 lbs. wet crushing ... ... ... 1'3 „ of „ 
The latter sample showed more gold than this in the uncrusbed stone. Even if the wet- 
brushed result be true, the proportion for this reef is 10'19 pennyweights. It was evident, 
however, that gold had been lost in the stamping box; had indeed possibly never left it, for 
the bed plate (fixed) could not be completely boxed in. 
The outcrops of these reefs are very short for any continuous distance, but there can be 
little doubt that they will he found continuing northwards nearly up to the Marpanmudi 
ridge; and some of them show down in the Nadgani estate in the Careoor cherrum. They 
are thin, about 3 to 4 feet on the edge of the cherrum, and look at other points as though 
they kept to this. Their appearance is very favorable, being more or less colored with oxide 
oi iron, laminated, and full of white iron-pyrites; and they show gold at times; in fact, they 
are just as promising-looking except in the matter of size as the l-eef to be noticed next. 
The Shull Reef. —The outcrop of this lode is traceable nearly continuously for 
about seven furlongs, but it is in all probability connected with other outcrops of quartz to 
a complete length of at least four miles. Only a small part of the southern end of this reef 
has been taken up by tire Alpha Company. At the soutbei'n end it commences on the edge 
of the Western Glikts, a little more than a mile and a half due west of the Nadgani Bungalow, 
on the rounded grassy knolls of this part of the Dayvallah country. Thence it runs up to 
the top of a high hill overlooking Dayvallah and down to the road a short distance east of 
the bazar. Strong leaders from its foot-wall cross the road nearer the village and run
