Discussion on “notes on underground conduits and cables” (Mosman), Boston, Mass., May 15, 1912. (see proceedings for May, 1912)

A. E. Kennelly: This paper manifestly embodies a large amount of valuable experimental work. It is work, as has been stated, done under very trying conditions, and we are all the more indebted to those who have done the work on that account. We have, it is true, known but little concerning the heating conditions inside ducts, although we know fairly well the heating conditions around a single cable of known dimensions buried at a given depth in the ordinary soil. I do not mean to say that we ought to be content with the knowledge which we have in that direction, but at least we have some knowledge.
