CHAPTER XIII

A STARTLING ALARM

Elfreda Briggs and Grace Harlowe did not give way to the panic that had seized their companions. Both had seen the mirage, each knew instinctively what it was, but when they saw Hi Lang overhaul the two leaders, Grace and Elfreda hurried in from their positions and joined their companions.

"Grace! Oh, Grace," moaned Emma as her friend rode up to them.
"Give me water or I shall die."

"Have courage, Emma dear. We are all suffering from thirst. Hand me your cup and I will give you a swallow. I don't dare trust you with the canteen."

Grace poured out about a tablespoonful of water, which Emma drank in one choking gulp. Each of the others got about the same quantity, but it was not much of a relief.

"Shall I return to my position now, sir?" questioned Grace of the guide. "Yes, please. I have told the others to do so at once. Hereafter, in no circumstances are you people to run away as you did just now. We must go on as rapidly as is consistent, until dark. I wish to reach a certain point before we stop for the night. We may find some relief there unless the storm has buried everything so deep that we cannot find the place," said Hi Lang.

"Do you mean water?" asked Elfreda.

"I am in hopes that it may be so, Miss Briggs."

"Alors! Let's go!"

The party broke up at once and rode to their positions, Emma Dean, red of face, her hair down her back, tear drops still trickling down her cheeks, leaving little furrows behind them, summoning all her courage and doing her best to regain control of herself.

The mirage had disappeared by the time the start was made, and did not appear again to tantalize the suffering Overland Riders. All the rest of the afternoon, eager eyes, reddened by the glare of the sun on the white desert, sought for water holes. None were found, not even dry tanks, but when darkness settled over the desert a faint breeze sprung up. They drank it in eagerly, taking long, deep breaths and uttering sighs of satisfaction.

Hi called the party together with a signal shot.

"How long before we make camp?" called Grace as she rode up.

"About five miles if my reckoning is right," answered the guide. "No need to look for water holes now that it is dark. We shan't find any unless we accidentally fall into one."

"You are about the most cheerful prophet I've ever known," declared Lieutenant Wingate. "Glad you weren't with us in the war."

"At least, Mr. Lang has made good all his forecasts. You must admit that," reminded Miss Briggs.

"He has, bad luck to him!" growled Hippy, which brought a grin to the thin, bronzed face of the desert guide.

It was nearly ten o 'clock when Hi finally ordered a halt. The Riders, upon looking about them, observed that there was considerable vegetation there, sage, cactus, dwarfed trees and shrubbery, scattered, twisted, misshapen things, all of them.

"Turn the ponies loose immediately," directed the guide. "They will get a little moisture from the green stuff. Never mind staking down. They will not run away. Ping, start a fire and cook something. Sorry, folks, but it will have to be a dry supper this time."

"Where is that relief you were promising us a century or so ago?" demanded Nora Wingate.

"Yes, Mr. Lang. We have been patient and borne our thirst uncomplainingly. Now, we MUST have relief. I don't want a dry supper, I want water!" cried Emma.

Anne said she feared that she too had about reached her limit.

"Be patient, girls. Mr. Lang is doing the best he can," urged
Grace.

"Yes, don't we know that?" agreed Miss Briggs. "He is splendid. I hope these unsolicited compliments do not turn your head, Mr. Lang," teased Elfreda.

The guide laughed silently.

"Come with me. We can pitch our tents later on," he directed, striding away. He led them through mesquite bushes, finally halting before a patch of odd, pumpkin-shaped cactus, that, with its grotesque shape, its spines and fishhooks, was far from being attractive-looking.

Hi's knife was out as he halted, and, with it, he laid open a cactus plant, revealing to the eager eyes of his charges a silver- white pulp glistening with water.

"This will relieve your thirst," he said, handing the white, moist mass to Emma.

"Oh—h—h—h!" gasped Miss Dean. "This is heavenly."

To each of the others Hi gave a handful of pulp.

"Nectar straight from Heaven," murmured Elfreda at her first taste. "Who would think that so much heavenliness could come from such a hideous plant, so hideous that, were I alone, it would give me the shivers to look at?"

Uttering exclamations of satisfaction and delight, the Overland girls ate and ate, soothing their throats and satisfying their thirst.

"Please tell us what this is, Mr. Lang," asked Grace.

"It is the bisnaga, sometimes called the 'niggerhead,' belonging to the cactus family, a plant that is ever hailed with joy by the thirsty traveler."

"It's a life saver," agreed Lieutenant Wingate. "Where is that
Chinaman? Doesn't he ever get thirsty?"

"Don't worry about him. He is out there in the bushes now, swallowing 'niggerheads' as fast as he can gulp them down. This is one of the secrets of the desert. There are others—but a man must know them before he can take advantage of them."

"Tell us about them. I just dote on secrets," exclaimed Emma, her good nature now fully restored.

"They might answer for an emergency, but nothing short of real food would answer for me," declared Hippy.

"Just the same a man might live on what we see before us here for a long time," replied the guide. "If you will examine those mesquite bushes you will find a bean pod on them. It is a rich and nourishing food. Then there are the pears of the tuna and the fruit of the sahuaro or giant cactus."

"We saw a forest of them on the Apache Trail," Grace informed him.

"Yes, I know. You will find all of these nourishing foods about you here, hideous, some of them, but furnishing food and water that have saved the lives of many desert travelers.

"Besides these food plants of the desert, we have the cat's-claw, mesquite and cholla shrubs for fuel; the bear-grass and yuccas for camp-building. Better than a mirage, is it not, Miss Dean?"

Emma flushed.

"I don't know about that. The sight of that lake that wasn't a lake made me forget for the moment that I was thirsty," answered Emma spiritedly.

The Chinaman's shrill call for supper sounded while they were still talking. The girls, now greatly refreshed, turned campward and sat down on the ground to eat "poisoned pig," as Hippy Wingate had named the bacon with its bitter alkaline taste.

"I fear we are forgetting that we still are without water," reminded Grace after they had finished their supper, feeling more like themselves than at any time in the last two days.

"Don't throw a monkey-wrench in the machinery," begged Hippy. "Let's live while the living is good, and die when we haven't anything else to do."

"Grace is quite right," agreed Anne. "I am worrying about to- morrow myself."

"I have been thinking it over," spoke up Hi Lang. "I believe I will go out early in the morning and ride until noon. I can cover a lot of ground in that time, and if I do not find water, the chances are against our getting any in the direction we are going. In that event we will head for the mountains and fight our way through. I never knew so many water holes to fail, but the storm is largely responsible for that condition."

"Why didn't we bring an artesian well with us? I have heard that one could have water anywhere with one of those. Are they very heavy to carry?" asked Emma innocently.

A shout greeted her question, and the guide brushed a hand across his mouth to hide his silent laughter.

"What's the matter? Have I said something funny?" demanded Emma, bristling.

"That would be impossible," answered Hippy. "No, Emma Dean, an artesian well would be no burden to carry at all if one were able to solve the problem of how to carry it. All the makin's are right here, too. Hi, why didn't you bring a medium-sized artesian well with you! I am amazed that you would neglect to find a way to bring one along," rebuked Hippy.

"You are all making fun of me. I think you are real mean," pouted
Emma.

"We're not," protested Hippy.

"Yes, he is, dear. Hippy, stop teasing Emma. She is worn out and irritable. By the way, Mr. Lang, what is an artesian well?" asked Nora, which brought down another shout of laughter, this time at her expense.

"I'm not irritable," objected Emma.

"An artesian well is a hole in the ground, Miss Dean," the guide gravely informed her.

"I'm going to bed!" announced Emma, getting up. "Am I to sleep in the open, or do we have tents to cover us to-night?" she asked with much dignity.

"Ping will pitch the tents. He is getting out the canvas now," replied Grace. "Before I turn in I am going out to eat some more 'niggerheads.' Any one going with me?"

All signified their desire to have more of the luscious white pulp, and in a few moments they were gorging themselves among the bisnagas.

The moon was now well along in its first quarter, and in the cool of the evening the Overland girls were in a frame of mind to appreciate and enjoy the scene.

"The desert has a strange and beguiling beauty all its own," murmured Grace.

"Yes," agreed Elfreda. "Such an evening as this makes one forget the awful heat, and lays hold of one's spirit. Then the silence— no whistling of wind, no rustling of leaves. Why, I find myself holding my breath so as not to break the silence."

"I had not observed it," retorted Grace, presenting a smiling face to her companion. "The camp should be ready by now. I move we go back and turn in."

"The mystery of it all, too," added Elfreda, turning to walk to the camp.

The guide told them not to be concerned at his absence if he did not get in until late on the following day, and the Overland Riders sought their blankets for a rest which all needed.

The night passed without one of the girls moving, so far as any of them could remember, when they were rudely awakened next morning.

Shouts and yells from Hippy Wingate, and a scream from Emma Dean, brought Grace, Elfreda, Anne and Nora to their feet, hurriedly throwing on sufficient clothing to make themselves presentable.

"Girls! Hurry, hurry!" shrieked Emma.

"Coming! Hold fast!" shouted Elfreda Briggs, running out ahead of the others.
