The physician looked grave when he saw the unnatural pallor of Edith's face, and noted her heart action.

"It is well Miss Bright brought you to me at once, Edith," he said.

"You need immediate medical attention. I wish you could remain with us a few days."

But she insisted upon returning with her teacher.

After a due amount of rest and refreshment, they started homeward, leaving Miss Gale at her boarding place. Then the two approached the ford again. The stream was higher than on the preceding day, and the waters raging.

Once more the spirited team dashed forward. Once more the carriage swung with the current; only, now, it was swifter and stronger than on the day before.

"Oh, this is terrible!" said Edith, grasping her companion's arm.

"Keep up courage, Edith," said Esther. "I think we'll make it."

But she noted the deathly whiteness of the girl's face.

"Steady, Rocket! Steady, Star!" said the teacher. Her own face grew tense and white.

She felt the carriage swing with a sudden lurch, and it began to dawn upon her that the horses might lose in the struggle. She lifted the reins, and called out above the roar of the waters:

"On, Rocket! On, Star! Once more, my beauties! Bravo! Oh, G.o.d, give them strength! On!"

She rose in her excitement, and swung the reins.

The n.o.ble animals struggled madly. Could they gain the opposite bank?

She was filled with sickening fear.

"On, Rocket! On, Star!" she urged again.

At that moment, the exhausted animals gained the mastery, sprang up the embankment, and stopped suddenly on the level beyond, quivering from their terrific struggle.

Esther gave the reins to Edith, and springing from the carriage, she stepped to the horses' heads, patting and stroking them. Her voice trembled as she said:

"Rocket, my brave, Star, my beauty, we owe our lives to you."

They whinnied as if they understood.

She put her cheek to their noses, she laughed, she cried.

"I believe they understand," she said.

"I feel sure they do," answered Edith.

When Esther climbed back into the carriage, she found Edith had fainted. She waited till her patient regained consciousness, and then they started homeward.

"Do you know," said Edith, after they had gone some distance, "we have had a very narrow escape? A little more, and we'd have been swept down the river."

"I didn't realize the full danger until we were in the midst of the torrent," said Esther. "There was no choice but to go on. I thank G.o.d that your life is safe, dear," she added, drawing the girl affectionately to her. "I hope our troubles are over now, and that you'll feel no ill effects from the fright."

They had covered miles of the return journey, and had reached the canyon road leading directly to Gila. Here, for a short distance, the canyon stream spreads wide, flowing over a pebbly bottom. The water sparkled in the sunlight like a stream of diamonds. In the shallows, the bed of the stream seemed jeweled with rubies and emeralds, opals and amethysts, as the pebbles below the crystal water shimmered in the late sunshine.

They were within a mile of Gila when they heard the sharp, shrill cry of wolves. Esther tightened the reins, and the horses fairly flew.

"Have we a gun with us, Miss Bright? We ought to have one. I always feel safer when I have a gun. You never know what you may meet on these mountain roads."

"Can you shoot?" asked Esther.

"Oh, yes; father trained me to shoot. Oh, those terrible wolves!" she said, as the shrill, mournful cries came nearer.

"On, Rocket! On, Star!" urged Esther, again.

The animals made a sudden lunge, and sped onward like mad. Around jagged turns they flew, as if inviting death; near precipitous cliffs they swung, till the driver was filled with sickening terror. On they raced, the wolves in hot pursuit.

"Oh, dear!" said Edith, looking back. "One large wolf is far in advance, and close upon us."

Quick as a flash, she stooped, took a great haunch of venison Dr.

Brown had sent to her father, and flung it behind them. Then she watched in intense excitement.

"Oh!" she exclaimed, striking her hands together, "the wolf has discovered the venison, and has stopped!"

With that, she took the whip, and gave the already excited animals a stinging blow. They leaped and plunged madly forward. Esther doubled the reins around her hands, and called in low, insistent tones:

"Steady, Rocket! Steady, Star!"

They had gained upon their pursuers, and the horses were running at furious speed.

"The she-wolf," said Edith, looking back, "is again following; but the smaller wolves are snarling over the venison."

"Ow-ee-ow," came the wolf-cry, shriller, sharper, nearer. Esther shuddered. She urged the horses on. Edith grasped her arm in terror.

"The wolf is just behind us!" she said.

Suddenly there was the report of a gun. Esther glanced back, and saw the wolf fall in the road. She glanced ahead, and, at first, she saw no one. Then, out from the shade of a group of pines, rode Kenneth Hastings.

"Whoa! Whoa!" he called, as he leaped from his own horse, and caught Rocket by the bits. With a sudden lurch, the team came to a standstill.

"Whoa, Rocket! Whoa, Star!" he called soothingly, as he held and quieted the team.

"Oh, thank you, thank you, Mr. Hastings!" said Esther. "When did you reach Gila?"

"We're _so_ glad to see you!" said both, as he stepped to the carriage and extended a hand to each.

"But how did you happen to be here?" asked Esther.

"I came in this morning. Mrs. Clayton told me you had gone to Carlisle, and would be back about this time. I have felt anxious about you ever since I heard you had undertaken this journey."

Again both repeated their grat.i.tude for his timely a.s.sistance. He could see they were trembling.

"Your horses were running away," he said. "They are nervous creatures, and are still frightened."
