And the last annual meeting of the company is called for May 8 next. At the end of 1022 the company held cash and investments and cash assets, after allowing for liabilities, to the' value of The amount pay able by the company under the Miners' Phthisis Act, 1919, on ceasing operations is estimated at In the course of his annual report, the Consulting Engineer, Mr. J writes In accordance with the decision made by the Board in 1017 to discontinue development, the operations of the mine have again been confined to extract ing ore already developed; a limited amount of internal work only having been done, amounting to 405 feet for the year mg to the dislocation of operations resulting from the strike, which extended from the l0th January to the 17th March, a serious loss, amounting to was sustained during the first three months of the year The profits during the succeeding months, however, more than balanced this loss, and a final profit of was obtained The working costs again showed a very material reduction of 4s 10d per ton milled, the average for the year having been 183 10d.

The cleaning up of the old workings and the reclaiming of pillars in the upper levels has been continued during the year, and the tonnage obtained from this source has been a large factor in maintaining profitable operations. Such work, however, has only a1 limited scope, and, with the small tonnage in reserve, it has become more and more difficult with each succeeding month to maintain the output. The mine is expected to carry on operations until the end of March, By that time all the payable ore in reserve at the end of 1917, together With other tonnage since developed, will have been worked out, and the company's milling operations will terminate The following tabulation summarises the salient features-of the work of the past three years' About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
