Abstract
THE August number of the Transactions of the Mining and Geological Institute of India is to hand. Most of the papers in it are of interest mainly to those engaged in mining work in India, but the first paper, by P. I. Keith-Murray on radio communication applied to mines, is of more general interest. The author has devoted considerable attention to the subject of radio communication, and has investigated in some detail the various methods with regard to their applicability to mining purposes, and more especially to mine rescue work. He has come to the definite conclusion that, so far, no place has been found for it in this work, but he also states that in view of the rapid development of all branches it would be unwise to make any definite statement as regards the impossibility of ever employing it in the future. He shows that a great deal of important work has been and is being done, and that new methods are being evolved at a tolerably rapid rate, and appears to hope that within a measurable distance one or other of these methods may be employed for underground work, though he points out fairly enough the very serious obstacles that its application would present.
