Ethel said nothing, and her mamma saw that she would rather go with her. Accordingly, Mrs. Hardy, Ethel. Sarah, and some of the lighter bags were packed into a light carriage, Mr. Thompson himself taking the reins, as he said he could not trust them to any one but himself. Mr. Hardy, the boys, and Maud mounted the horses prepared for them, and two of Mr. Thompson's men stowed the heavier trunks into a bullock cart, which was to start at once, but which would not reach the estancia until late at night. As the party rode through the town they were struck with the narrowness and straightness of the streets, and at the generally European look of everything; and Mr. Thompson told them that nearly half the population of Buenos Ayres are European. The number of people upon horseback also surprised our young travelers; but horses cost only thirty shillings or two pounds, and grass is so abundant that the expense of their food is next to nothing; consequently every one rides--even shepherds look after their sheep on horseback. The horses seemed very quiet, for in front of most of the offices the horses of the merchants could be seen fastened by a head rope to a ring, grooms not being considered a necessity. Once out of the town, the riding horses broke into a canter; for the road was so good that the horses in the light carriage were able to go along at full speed. As they proceeded they passed many houses of the rich merchants of the place, and all were charmed with the luxuriance and beauty of the gardens. Orange and lemon trees scented the air with their delicious perfumes; bananas, tree ferns, and palms towered above them; lovely butterflies of immense size, and bright little humming-birds, flitted about among a countless variety of flowers. The delight of the young ones was unbounded. Presently they left the mansions and gardens behind and drove out fairly into the country. Upon either side the plains stretched away as far as the eye could reach, in some parts under the plow, but far more generally carpeted with bright green grass and many-colored wild flowers. Everywhere could be seen droves of horses and cattle, while dotted here and there over the plain were the estancias of the proprietors. It was a most delightful ride. The horses went very quietly, but the boys found, to their surprise, that they would not trot, their pace being a loose, easy canter. The last five miles of the distance were not so enjoyable to the party in the carriage, for the road had now become a mere track, broken in many places into ruts, into which the most careful driving of Mr. Thompson could not prevent the wheels going with jolts that threatened to shake its occupants from their places, and they felt as if every bone in their bodies were broken by the time they drew up at their host's estancia.
