The commandoes on our side of the river were extended to keep pace with the enemy’s movements on the other.  The distance between the different laagers lengthened considerably, and a speedy and certain method of communication soon became a necessity.  To obtain this use was made of the vibrator, an instrument so sensitive that the most faulty line will carry sufficient electricity to work it.  Having received orders to accompany the construction party, I said good-bye to my comfortable quarters, and found myself in the veld once again.

While the two waggons loaded with wire, etc., went on by road we struck across country, myself on horseback, a vibrator strapped to the saddle, the others on foot.  Half a dozen Kafirs accompanied us, carrying rolls of “cable,” wire about the thickness of the lead in a pencil and covered with gutta percha.  A wooden “saddle” holding one roll of wire was strapped on the back of one of the natives, one end of the wire joined up to the instrument in the office; the native marched forward, the wire unrolling as he went, and the other boys placing stones upon it here and there in order to prevent its being dragged about by cattle.  In this manner we went forward, establishing an office at every laager on the way, with the result that every commando was always fully informed as to the situation of all the others, and the enemy’s every movement immediately known to the entire forces, enabling reinforcements to be sent anywhere at any time.

This system was an easy one to learn, and it has been said that some of our generals became so fond of it that the slightest movement of the enemy was the signal for a request for reinforcements.  This is, no doubt, a frivolous exaggeration.

The first day of laying the cable we had gone about fifteen miles, when communication with the office suddenly ceased.  Telling the others to go on, I turned back and carefully tested the line, eventually finding the fault at sundown.  Reporting my whereabouts to the office, I was ordered to follow the working party as rapidly as possible, the chief adding that it was especially desired to have communication the same night with the Standerton laager, where the others would have arrived by this time.  I therefore pushed on, following the wire.  It was pretty dark when I reached the foot of a mountain.  Right across the cable led me—­rather a difficult matter tracing it in the dark—­but at last an open plain on the other side was reached; a few miles further I found one of our men stretched out in the grass by the side of the cable.

“Where’s the Standerton laager?”

“This is where it was.  Shifted yesterday; don’t know where to.  Others gone to find out.  Got a blanket?”

I had not.  We had no idea where the waggons were.  We lay down to shiver, not to sleep, for the intense cold made the latter impossible and the former obligatory.  In the middle of the night we moved round to the other side of the antheap, thinking it must be warmer there.  But it wasn’t.
