§ Mr. T. JOHNSTON
asked the Secretary for Mines if he can make use of the cage-arresting device designed by Mr. Robert Collins, of Campsie Glen, and which was being considered by his Department as far hack as April, 1923?
§ Mr. SHINWELL
An inspector of mines visited Mr. Collins and went carefully into the device with him. Its principle is not new, and Mr. Collins'1592W invention, like others that, have been proposed from time to time on the same lines, cannot, I understand, be considered practicable.
