    — I think it of great importance that the whole of this portion of the Brecon and Mertyr Railway, which originally was an old mineral line (the old Rumney), should be carefully examined by the Company's engineer, to ascertain if there are any other curves of 10 or 12 chains radius or less on the running lines, and that such curves should be rendered more safe, by the addition of check rails round such curves.
