Of oonrse the cable is lead covered and otherwise protected, but it depends for its insulatioa, electrically, on thin spirals of paper around each strandod interior wire. The laying of such a cable in such a place might, a few yearsago, have been considered little short of suicidal, but esperience has demonstrated the perfect practicability of the Rcbeme. In considering the laying of such cables iu such situations the fact is important tliat a 100 pair, paper insulated, lead covered cable can be bought for 60 cents a foot, while the rubber insulated cable would probably cost flot less thau tí! per foot, while, figured ou the basis of equal electrical effectiveness, the price wonld be 50 or 100 to 1 in favor of the paper cable,
