THE LIVE-WIRE BARRIER
" At present Formosa enjoys greater freedom from savage attacks than ever before in her history. This is due to the fact that the Japanese have installed a live-wire barrier from Karenko, about midway on the east coast, to Pinan, in the south, a distance of about a hundred miles, to serve as a protection against savage raids.
The trees for twenty feet on both sides of the barrier have been cleared away to prevent the savages from crossing the wire by felling trees on it.
At distances of every half mile along the route blockhouses are stationed, and a sentry paces the beat between two posts all day long to see that the wire has not been tampered with or any holes burrowed underneath.
At first the electric current was turned on only at night, the usual time for a savage raid, but the wily head-hunters soon discovered this, as they noticed that no smoke issued from the power-house by day. Then, as they turned their night raids into daylight expeditions, the Japanese were obliged to turn on the current by days as well."
