"I think you will have to change the name of your club from the 'We are Sevens' to 'The Rainbow Quintet,'" said the Señora, laughing as she wrote down the variegated list.

After all it was a delightful drive to Jonah. The two fleet horses drew the light buckboard over the smooth road with a motion that Sarah found far preferable to the cat-like leaps of Comanche; and Blue Bonnet was so proud of being trusted to drive a team that she was quite reconciled to the arrangement.

"Denham would have fainted if I had even suggested driving Grandmother's carriage horses," she told Sarah, with a scornful sniff for those fat Woodford beasts.

"You drive beautifully," was Sarah's comforting rejoinder.

To their great satisfaction they found just what they wanted in Jonah. Alpaca was to be had in almost every shade, and wide white braid that made an excellent trimming. And to Blue Bonnet's delight she found a bright red sash that would add the finishing touch of elegance to her suit. Their shopping done and the buckboard well-heaped with their varied purchases, the two girls drove back as far as Kooch's ranch, where, according to an immemorial custom, they lunched and rested until the cool of the afternoon. On the return trip they met with an adventure.

The road ran for a short distance beside the little river with the big name—San Franciscito—which had so amused Alec. It was there that Sarah did something unprecedented. For several miles she had been envying Blue Bonnet her easy manner of handling the reins and the light touch that sent the mustangs right or left as she willed. It was a beautiful accomplishment.

"Blue Bonnet," she asked suddenly, "may I drive for a little while?"

Blue Bonnet looked up in speechless surprise; Sarah was certainly "coming on." "Surely you may," she said cordially, straightway handing over the reins. "Hold them firmly—these colts are apt to run under a loose rein."

Sarah felt a curious sense of power as she grasped the leather in her unpracticed hands. Conscientious to a degree, she did as she was bid and held the mustangs firmly. In her anxiety to do the thing properly, she overdid it, and the next moment the horses were tossing their heads angrily and backing with all their might. The bank of the stream just here was very high and steep, though just beyond was a ford where the road branched. The light buckboard offered no resistance to the spirited mustangs, and, in a second, before Blue Bonnet could grasp the reins, one hind wheel had slipped an inch or two over the ledge. For a second or two the girls were in grave danger. Blue Bonnet felt a swift overpowering fear; the half-broken colts were as apt to plunge backward as to advance if they felt the whip, and that meant a plunge down the steep bank. She looked about her helplessly. Sarah, with a faint shriek, shut her eyes and prepared for the catastrophe.

At that moment a horseman came suddenly up the bank at the ford, emerging as if from out the earth. At a glance he took in the situation, was off his horse, caught the near colt by the bit and brought both frightened animals to a standstill with the wheel a safe margin from the bank. Then without waiting to hear the faintly murmured thanks of the terrified girls, their rescuer turned at once to his own horse, which had seized the moment to make a break for freedom. The boy—for he was hardly more—had thrown the lines over the animal's head and now, with another of his incredibly swift movements, he caught them and in a second more had jerked the horse about. Then in a flash he was once more in the saddle. Blue Bonnet had just managed to catch her breath,—when it was taken away again. For before the boy had put his right foot in the stirrup, he was out of the saddle once more, lying all of a heap in the grass, while his horse with a wicked kick-up of his heels, vanished around a turn in the road.
