We are informed by Messrs. John D. Hum- phreys and Son, General Managers of Olivers Freehold Mines, Limited, that they have received a telegram from the mines giving the result of the September orushing as follows:-"585 tons of quartz crushed for a yield of 452 ozs. retorted gold. Mill ran 25 days."
Messrs. John D. Humphreys & Son also inform us that in a letter they have received from Mr. J. Whear Roberts, consulting engineer to Olivers Freehold Mines, Limited, dated 6th September, 1899, he writes as follows:
Eureka Mine.-At the mine work was being carried on vigorously in the southern section on the new ore body with results which are most satisfactory and with prospects which are hopeful in the extreme as to a continuance of these results. The whole of the stuff crushed daring the past month came from this southern section with exception of a few tons from be- low the 150 feet level north. Here it may be stated that as far as is at present known practically the whole of the ore of sufficiently good quality to pay with the existing appliances has been worked out in this northern section, but there is still a probability that we may find a continuance of these shoots below the 200 feet level. As soon as convenient we shall extend the 300 feet level north indefinitely. This will be the best prospecting work which can be done in that direction. At the same time we shall extend the 150 feet level north to connect with B Shaft.

modelling of the orushing plants so as to get greater efficiency and economy in the treatment of the ore. Meanwhile arrangements are being made to equip the shaft with cages, which will save much expense in the handling of the ore, and also in wear and tear gen- erally.
In my last I mentioned that we were likely to have some difficulties in the disposal of the sludge. The trouble has now become so acute that there is nothing for it but to immediately proceed with the construction of another em- bankment about 250 feet below the existing bank, I was in hopes that we could avert this expense pending consideration of the question of the redisposition of the crushing plant, but it is impossible.

The following is the Mine Maunger's Repor for the months of July and August 1899
RAUB HOLE.
At the date of my last report we were getting some phenomenally rich or, 1,010 ounces per ton, in a small chute of stone we had out 50 ft. down the winze below the 220 ft. level. This chute of gold bearing stone proved to be about 22 ft. across, the very rich part being about 10 ft. across; it has a slight dip North. After passing through the chute into formation only I decided to stop driving and sink the winze another 50 ft. to test it again at that depth, this will make the depth 320 ft. from the surface,
This chute, should it continue the same as in the drive higher up, although small, will tura out a lot of gold, but I hardly think it would pay to sink the main engine shaft 200 ft. to work this chute alone, and unless something more can be found I intend to take the payable ore out from the winze. The air has been very bad in this winze of late and ouly slow progress has been made with the sinking. The winze is down 76 ft. below the 220 ft. level and 26 ft. below the gold.
East Crosscut.-This is now in 306 ft. from the 220 ft. level in hard black slate. We have

GOLD MINING CO., LIMITED.
The General Agents of the Great Eastern and Caledonian Gold Mining Co., Limited, Messrs. Luetgens, Einstmann & Co., have re- ceived the following report from the mines, written by Mr. Thomas Čash :-
Since my last report there is nothing fresh to mention now, only at the Caledonian mine. The drive north of old main underlie shaft ha been extended a further distance of 12 feet making total length from old face 30 feet. The reef is very well defined and it is still five feet wide and carries a very good hanging wall, The stone in the face according to mortar pros- pects will yield about 8 dwts. of gold per ton. but it is almost impossible to judge the value of such a big reef without making a test crushing of say (200) two hundred tons. At present there is over 80 tons of stone at grass and as soon as the new cams have been put on the bat- tory there will be sufficient stone out to make the test crushing. I have every reason to believe this mine will prove payable when it is put in working order by sinking the air shaft and driving the main levels north and south at the bottom of the new main shaft.

BUKIT HITAM- Nothing has been done in the new engine shaft since the date of the last report.
A larger pump, 8in. double acting steam pump, has been put in the old engine shaft, as the water was too heavy for the previous one, & 6in. pump. We have no difficulty now in keeping the mine free of water.
As soon as we can spare the time I intend to fix an 8in. draw lift in the new engine shaft and resume sjúking to 150 feet before opening out the first permanent level to work this mine. I will have this done as soon as we finish the erection of the pumping and winding plant now being erected at No. I north shaft, Bukit Koman.
In the meantime I have continued the pro- specting work in the present workings
The Main Drive going North has been drivon 48 feet on a large irregular lode carrying a little gold. As this drive was making a large quantity of water and increasing rapidly I decided to stop it for the present. A small orosscut was put in at the end proving the formation to be about 18 inches wide, but it is a good deal disturbed. This end, is now 209 feet from the shaft.
South End.-The main drive is now in 306 feet from the shaft. the whole distance on a lode which varies from 18 inches to 30 inches in width and carries first class gold. The lode is now about 3 inches wide in the face of the drive and I estimate that it will yield 2 to 3 ounces per ton of ore. The stone is a nice kindly class of ore carrying a large quantity of mineral in the stone principally sulphide of antimony. The lode continues solid and well defined.
An air shaft, No. 2 South is now being sunk to ventilate this end, as the air is getting very bad.
Beverting to the southern section, you will note that the results, satisfactory as they are, as regards profit, cover a large amount of develop. ment work. Certainly the drives at 150 foot and 200 feet have been in ore all the time, but still this is work which may fairly be classed as development." The intermediate level now ranks in the same category. When I was at the mine the Calcite Cross course which was our in. dicator in the levels above had just been passed through and you may judge as to the regularity of this new formation when I tell you that we calculated to an inch where we should meet with payable ore. I told Mr. Banks that on a certain afternoon we should get a telegram announcing the striking of the ore, and sure Bank of England Mine-The main drive enough the message came at the anticipated north has been extended (3) three feet, making bour. You will recognise the importance of total length from main shaft 81 feet. There are the mention of these incidents when I point still two reefs in the face.

Mr. Georg has decided to stop all that the lode is very strong under foot.
