Roger and Ernest were at work on this task one morning when Gustav returned with a barrel of water from the ranch. Before driving back with the team he came excitedly round the corner of the engine house.
"The alfalfa vas up already!" he shouted. "A little shadow of green on yellow sand. Lieber Gott! vat a country! And the kleine Felicia almost eating it like a little rabbit. And Dick talks like it vas golt. And he vas vorried. He says a sand storm vas coming to-day. Look!"
Gustav pointed down the valley to the south. A gray blue haze, not unlike a sea fog, was slowly advancing.
"Fasten up the tents. I go back mit the horses," said Gustav, disappearing as abruptly as he had arrived.
"If any one thinks a little thing like a sand storm can stop work on the plant, he's mistaken," grunted Roger. "Anyhow Dick said one wasn't due for six weeks."
Ernest looked from the approaching gray cloud to Roger's obstinate mouth, shrugged his shoulders and daubed another brush full of hot asphaltum over a crack.
Suddenly a hot blast of air took their hats off. The tent gave a boom. The window-sash resting against the engine house wall fell with a tinkling crack. Without a word the two men ran to close the tent. When they had finished, the whole world was a swirling dust cloud through which they could not perceive each other when ten feet apart.
"Make for the engine house!" roared Ernest. "I'll fetch the old lady."
He was better than his word for he brought not only the madam, but her rocking chair and a book. Certainly no one could have accused their visitor of being a trial. She took the storm with the utmost philosophy and spoke scarcely a hundred words until the storm was over.
When he had stowed Mrs. von Minden and her rocker inside Ernest slammed the door shut and turned the button. "If Gustav tries to get back through this, he'll lose his way, without fail," said Roger.
"How long do you suppose it'll last?" asked Ernest.
"The Lord knows! Have you got any tobacco with you?" Roger sat down on a box of window glass and took out his pipe. For half an hour they sat listening to the howl of the wind while Madam read.
"Evidently it doesn't intend to quit for a while," said Roger finally. "Guess I'll make up my diary and write some letters. I understand now why Dick was so insistent on this adobe. You take a look at the cook tent and I'll see if the house tent is still standing while I get some paper."
