similar to those obtained from the gold-fields of Bendigo, Castlemame, and 
Daylesford, in the vicinity of the richest mines, are met with within 200 yards 
of the present workings. 
[ 22 . 11 . 12 .] 
Certain works recommended in my report of 22nd November, 1912, have 
since been undertaken, but the results have not come up to anticipations. 
The shaft at the date of my previous visit was 65 feet deep, with a cross-cut 
east 25 feet to two vertical makes of quartz on which a winze was being sunk. 
Since then the shaft has been deepened, and a cross-cut east opened at 93 feet. 
At 25 feet from the shaft a fault dipping west was met with, and the vertical 
makes of quartz showed only as a wedge in the back. On rising on this stone 
a connexion was made with the winze from the level above, but, not meeting 
with the stone below the slide, some of the party have formed the idea that 
the stone is of limited extent. From the features exposed there is nothing 
to warrant this idea, as the fault makes a clean break in the stone, which will 
be found again below the level. Two methods of locating the stone below 
the slide are suggested, viz., to drive northerly under the slide which 
pitches south, or to sink the shaft, say, 20 feet and cross-cut. From indica¬ 
tions, I would anticipate a displacement of under 20 feet by the slide ; this 
would place the reef nearer the shaft below the present cross-cut, and on the 
east side. From the fact that the stone above the slide is auriferous, and a 
trial crushing of 10 tons from the winze gave 5 oz. 10 dwt. of gold, the testing 
of the formation below the slide appears justifiable. At present some 25 feet 
of backs above the lower level and beneath the top slide are available, and 
these, if supplemented by an additional quantity below the lower slide, should 
induce the prospecting party to develop further what appears to be a promis¬ 
ing locality. 
The lower level being below water-level, a quantity of water—2,000 
gallons per diem—has to be baled, but it is not anticipated that any material 
increase in quantity would be met with in, say, 25 feet of further sinking. 
By driving south at a lower level the quartz above the slide may be tested, 
but I would prefer to see the shaft deepened and the formation tested at a 
depth.

DEAN’S MARSH COAL MINE. 
* 
By Stanley Hunter, Engineer for Boring. 
The Dean’s Mar sh Coal mine is situated about 7 or 8 miles from Dean’s 
Marsh, on the road to Lome. The coal seam is in a Tertiary deposit of sand, 
clay, &c., resting on Jurassic sandstone. The area of the Tertiary deposit 
is probably not more than 100 acres, while the area of the coal seam will 
certainly be much less, and may occupy not more than 15 or 20 acres. The 
seam varies from 5 to 6 feet in thickness, with a general dip to the north¬ 
west. 
The method adopted to develop the seam was by dip-tunnels. A pair 
of shafts at the dip end of the seam would have been the proper method. 
These dip-tunnels were put in close to the creek and on the outcrop of 
the coal. The first flood filled the workings. A tail race was then con¬ 
structed, but the creek water still gave trouble, and as no pumping machinery 
had been considered necessary the mine had to be abandoned. A railway 
line was brought in from Dean’s Marsh at considerable cost, and a very poor 
system of rope haulage from the tunnel to the top of the ridge, along which
