"How big is it, Mick?" asked Vaughan.
"Between six and seven thousand square miles."
"Miles! You mean acres, don't you, Mick?"
"Acres be blowed! No, miles. This isn't a cocky farmer's cow-paddock."
The extent of country amazed the boys. They were standing on a pretty high hill and could see over a vast scope of country, but Mick told them that a certain landmark near the head station was not even in sight, and that the run stretched on beyond that again for miles and miles.
"But how ever do you know when you've gone off the run?" asked Sax. "Is it fenced?"
Mick Darby laughed heartily. "Fenced!" he exclaimed. "Fenced! Oh my hat! No, lad, there's not a fence between here and glory, except round a little bit of a paddock where they keep the working horses over night. Why, d'you know that to fence Sidcotinga Station you'd need nearly four hundred miles of fencing? There's no timber for the posts in this part of the country, and as for wire—— No, they don't use fences in Central Australia."
This was such a new point of view to the boys, that during the afternoon's ride they asked innumerable questions of their kind-hearted friend. They heard that cattle are kept on any particular run because of the impossibility of their wandering more than a certain distance away from their water-hole. In fact, a run is made up of permanent waters and the area of country around them. There may be any amount of good feed on other parts of the run, but unless it is within reach of water it is absolutely useless.
The only chance that cattle have of straying is after rain, which falls very, very seldom in Central Australia. When it does fall, the stock wander off to new feeding-grounds, and may become stranded when the surface waters dry up. The stockmen are very busy at such times, tracking up cattle and bringing them back to their accustomed haunts.
All this and much more the boys learnt as they rode along, and although it seemed so new to them, there was a splendid sense that they were in it all, and that soon they would know these things from actual experience.
