Mr. Hardy at last sent Charley back, accompanied by Mr. Cook, to request Mr. Percy to come on at once with the Gauchos to give their opinion. Charley and his companions were to remain with the horses, and were to request those not specially sent for to stay there also, as it would be imprudent in the extreme to leave the horses without a strong guard.
Pending the arrival of Mr. Percy, Mr. Hardy and his friends followed up the trail for some distance, so as to examine it both in the soft bottoms and on the rises. They returned in half an hour to their starting place, and were shortly after joined by Mr. Percy and the Gauchos. Again a careful and prolonged examination, took place, and a tolerably unanimous opinion was at last arrived at, that a very large number of animals had passed, apparently the larger half, but that no positive opinion could be arrived at until a comparison was made with the trail on the western side.
Although this conclusion was arrived at unanimously, it appeared to be reluctantly conceded to by most of them, and the reason of this became apparent as they were walking back toward the horses. "I have little doubt that the conclusion we have arrived at is correct," Herries remarked, "although somehow I am sorry for it; for ever since our talk last night I have made up my mind that she was most likely to be taken to the west. I suppose because the Indians there are more warlike than those of the pampas, and therefore likely to have furnished a larger contingent. Of course I had no reason for thinking so, but so it was."
"That was just what I thought," Hubert said; and I the other Englishmen admitted that they had all entertained a somewhat similar idea.
At four in the afternoon they were again in the saddle, having taken the precaution of filling their water-skins, and of watering the horses the last thing.
"How far do you think it is across, papa?" Hubert asked.
"It cannot be very far, Hubert. We are so much nearer the place where the fire began that I do not think it can have spread more than ten miles or so across."
Mr. Hardy's conjecture proved to be correct. An hour and a half's riding brought them to the other side of the burned prairie, striking a point which they felt sure was to the south of the place where the trail would have left it.
As they had done more than fifty miles since the morning, and the horses were much distressed with the effect of the dust, it was resolved to encamp at once. The horses received a little water, and were picketed out to graze. The fire was soon lit, and the ducks cut up and spitted upon the ramrods.
All were so much exhausted with the heat, the ashes, the fatigue, and the want of sleep of the previous night that, the tea and pipes finished and the watch posted, the rest lay down to sleep before the sun had been an hour below the horizon.
