"I never saw a road that was better than this!" exclaimed Jo in delight. "It is perfectly springy and no dust or mud."

It deserved all of Jo's praises, this broad, firm California beach. The brown sand, that had been pounded down by the force of the great rollers some hours before, showed scarcely a sign of the shoes of the horses.

There was plenty of width and the three horses pressed on abreast, the powerful sweep of the gray Caliente and the chestnut Don Fernando, and the snappy, nervous leaps of the little bay that Jo was riding. With the bracing sea air and the exhilarating speed, the three musketeers were invigorated.

The Spaniard hummed a gay ballad, while at times Jim's heavy bass and Jo's lighter treble were joined in a rollicking American song. They laughed without reason, for the simple joy of being alive and on the move; but as pride sometimes goes before destruction, so happiness often goes before disaster.

It was a small matter too, but it made for trouble. The Spaniard's horse stepped between two small rocks that were close together and wrenched one of his hind shoes nearly off. Jim and Senor Sebastian hastily dismounted. Of course they carried with them the necessary things to fix the shoe on again, but even then it was a question of a number of minutes.

"You had better ride ahead, Jo," urged Jim. "Your horse is beginning to tire and we will overtake you, when we once get started."

"It is a good idea," joined in the Spaniard.

"All right," acquiesced Jo readily enough, and he gave his bay the rein, riding slowly down the beach.

Then the two began operations on Don Fernando's hind foot. Here they found their first real delay. At the point where the accident happened, the mountains came down quite close to the sea, so that they were crowded in much closer than they had been. The nearness of the water made the big chestnut restless and hard to handle.

The Spaniard had great difficulty in getting near enough to his horse to get hold of his hind foot. When he did succeed in doing this, and was just starting to peg the shoe on, an extra big wave slapped down upon the beach, though at a safe distance and caused the big chestnut to jump and hurl his master to a distance of a dozen feet.
