"I fear it is impossible to start so soon," replied the Spaniard, "I must go with you as I know the country to the South, every foot of it."

"The Senor is right, Jim," put in Jo, quickly, as he saw a frown on Jim's face and was afraid that he was going to say something abruptly. "You will want to give Caliente a good rest, so that when we start, we will make the distance without delay. Then we have to make some preparations ourselves."

Jim looked at his brother with a moment's dark suspicion, but it was evident that Jo was perfectly sincere in what he said.

"I will promise, Senor," said the Spaniard with a peculiar smile, "that when we start which will be early tomorrow morning, that we will travel far and fast enough to suit you and your horse." There was a challenge in his voice that Jim met smilingly.

"So be it, Senor," he said, "I will try to be in sight at the finish."

"My horse is a remarkable animal for speed and endurance, I must tell you frankly," said the Senor gravely. "He has no equal in this country of California. He has proved it more than once and against all comers."

"He is certainly a fine horse," admitted Jim, looking at the sorrel with admiring eyes. "He has a splendid stride."

"Ah, no, Senor," laughed the Spaniard with a gleam of his white teeth, "I did not mean him," patting the horse on the neck, "a good animal, indeed, but more for my little sister to ride than for me. Wait, my friend, until I introduce you to Don Fernando and then you will see a horse for the first time."

"I should be very much pleased to see him," said Jim, frankly curious and interested.

"Tomorrow," said the Spaniard.
