Mr. Hardy and his sons then took possession of the one near the brow of the hill. This was to be merely a temporary abode, to be removed when the house was built. The men had that lower down, and rather nearer to the cattle. Beds of rushes were piled up in three corners, and the boys thought that they had never passed such a delicious night as their first in their new house. The next day Mr. Hardy told his boys that they should take a holiday and ride over the place. The press of work was over, and things would now settle down in a regular way. Hans and Terence had taken a contract to dig the holes for the posts of the strong fence which was to surround the house, including a space of a hundred yards square. This precaution was considered to be indispensable as a defense against the Indians. Seth, the Yankee, had similarly engaged to dig a well close to the house. No supervision of them was therefore necessary. Lopez was to accompany them. Each took a double-barreled gun and a revolver. The day was very fine--about as hot as upon a warm day in June in England. Mr. Hardy proposed that they should first ride westerly as far as the property extended, six miles from the river; that they should then go to the south until they reached that boundary, and should follow that to the river, by whose banks they should return, and bring back a bag of wild fowl for the larder. Quite a pack of dogs accompanied them--the two mastiffs, the setters, and four dogs, two of which belonged to Lopez, and the others to Hans and Seth: these last, seeing that their masters had no intention of going out, determined to join the party upon their own account. These dogs were all mongrels of no particular breed, but were useful in hunting, and were ready to attack a fox, an animal which swarms upon the pampas, and does great damage among the young lambs. For the first three or four miles nothing was seen save the boundless green plain, extending in all directions; and then, upon ascending a slight rise, they saw in the dip before them two ostriches. Almost simultaneously the creatures caught sight of their enemies, and went off at a prodigious rate, followed by the dogs and horsemen. For a time their pace was so fast that their pursuers gained but little upon them. Presently, however, the dogs gained upon one of them, and, by their barking and snapping at it, impeded its movements. The horsemen were close together, and the boys had drawn out their revolvers to fire, when their father cried, "Don't fire, boys! Watch Lopez."
