We have, first, a very erroneous impression gone forth, to the effect, that after the commencement of the new Mines Bill, on the first day of the present year, no pit, or no person in a pit, must work more than 10 hours per day, or 54 hours in any one week. In the Minutes of Committee Meeting, held on the 4th inst., we clearly and distinctly stated that this view was a wrong one. We again beg to emphatically state that the law, in this particular, affects only boys under 16 years of age, and that so far as regards all parties above this age, matters remain identically as they have been. It would appear, however, that in the face of this intimation, some collieries of men are still insisting on the general adoption of the 10 hours per day, and 54 hours per week. In addition to this, we have existing at many collieries, both where men work two and three shifts per day, difficulties as to what the working hours ought to be. Under these circumstances, the owners asked your deputation to meet them last week, for the purpose of discussing, and if possible arranging, some understood mode of action. This meeting took place, at Newcastle, on Friday last. The first question asked was, what objection we had to owners working their pits 11 hours per day, and 11 or 12 days per fortnight as usual, so long as they did not violate the Act of Parliament relative to boys under 16 years of age? After talking over the matter for a long time, we retired, and in consulting among ourselves, failed to see any reason why pits should not draw coals 11 hours per day as heretofore they had done. We returned and told them that we could see nothing to prevent them from working the pits 11 hours per day, if they thought desirable to do so, and they could find men or boys to bring the coals to bank; but that, in trying to carry this into effect, they must not keep men laying at their work for the last hour doing absolutely nothing, as, if such cases did occur, they would most certainly be complained of, and a remedy sought by an appeal to the Joint Committee, in which case they would be exposed to the entire county throughout. Respecting boys being brought into the pit an hour or two after work commences, or sent home an hour or two before the pit is done at night, we cannot see that any difficulties should exist. The question was asked, should a boy be sent home for the first 5 days, having worked less by far than the allotted 10 hours' per day, and such boy should purposely remain at home on the Saturday, would such boy claim his 5 days' pay, remembering that for 5 days he had worked short time for the very purpose of going to work on the Saturday? To this the owners demurred, when we suggested the desirability of seeing boys, or their parents, and making with them necessary arrangements.
