Stone Dust in Collieries What the Home Secretary says : In a 'recent official communication the Home Secretary writes :—“ It will be necessary to embody ithe recommendations in statutory regulations under the Coal Mines Act, but I would urge owners most strongly, without waiting for the formal settlement of the regulations, to take the matter into immediate consideration... “ The Committee have not in the report recommended the adoption of stone dusting to the exclusion of watering, but it is generally recognised that any system of watering which idoes not render inert the dust, not only on the floor, but on the supports and sides, would not be equivalent to the system of stone dusting recommended by the Committee.” DARLINGTON’S HANDBOOKS. “ Nothing better could be wished for.”—British Weekly. “ Far superior to ordinary guides.”—Daily Chronicle.
