The No. 3 quality of asbestos, which has hitherto been the main produce of this mine, fetches so low a price in the market that alone it would not pay for working. This, as already explained, is mainly on account of its bad colour and general coarse quality. This latter having somewhat improved, a considerable proportion of the produce would cease to be classed as No. 3 if it were not for the bad colour. It therefore occurred to me that it might be possible to remove this defect without injuring the fibre, and in consequence I had some experiments made with this object in view, and ultimately succeeded beyond my expectations, in replacing the discoloured fibre by one sufficiently bright to enable it to take rank as No. 1. These experiments, it is true, were only conducted on a limited scale, but, so far as I am aware, there is no reason why it should not be done on a large scale, which would very materially increase the value of the article. There is ample room for opening up in a more judicious way on other parts of this property on what seems likely to be good paying ground; and a mode of doing this without incurring any further expense might easily be devised, and, if this were done, other seams of better quality might be hit upon. Another point in the company's favour is that, if judiciously selected, there is abundant room for dumping without encroaching on the ore-bearing grounds--a most important matter when consideration is taken of the enormous quantity of waste rock to be here encountered and removed. The buildings on the estate are well constructed, and are in an efficient state of repair, but at present there is an insufficiency of dwelling-houses on the property. These are a necessity in the district, for securing and retaining a better class of labour. No great expense would have to be incurred in supplying this deficiency. Lumber and labour are both comparatively cheap, and the buildings in themselves, moreover, would always return a fair interest on the outlay. The property on which the "Martin" Mine is located closely adjoins the last mentioned. This has recently been acquired by "The Scottish Asbestos Company," of Glasgow, with the intention of working it in conjunction with their mines at East Broughton. Judging by the elaborate preparations for work which are being made, and the expenditure which is being incurred in buildings and machinery, it is evidently the company's intention to carry on work vigorously in both places. Their property at Black Lake covers 102 acres, and is described as being a mile long by 520 feet wide. The output is given as 300 tons, but I should doubt very much if it has yet reached this figure.
