"Not a thing. The equipment has been securely packed. I had Ping put the rifles in a sack and stand them upright in a hole in the ground so we may find them after the storm. Without weapons we should be in a bad way, especially if our friends, the pirates, return, but I reckon that what's left of that crowd will be pretty well sanded. This storm is going to pile right up on the range that we left behind us."

A distant, menacing roar now became audible to the two men, such a roar as one can hear by placing an ear to the opening of a conch shell, but magnified perhaps a million times.

The cool breeze, that had shortly before warned Hi Lang, now became a chill blast, moderate, but plainly thrust ahead by a mighty force behind it.

"Good night!" exclaimed Lieutenant Wingate. "That breeze must have been born up in Iceland. Talk about your heat on the desert! Perhaps we shall have some cool weather here after the storm passes."

Hi Lang laughed.

"Don't fool yourself, Lieutenant. It will be hotter than ever to- morrow, blistering, sizzling hot; and the water courses probably will dive deeper into the earth and give us no end of trouble to find them. I—-"

"It is coming, isn't it?" questioned Graces who had been awakened by the breeze and had come up behind Hippy and Mr. Lang without their hearing her.

"It's well on the way, Mrs. Gray. Perhaps it might be well to awaken the young ladies. Knock down your tents and sit on them or you won't have any tents left. Reckon we'd better do the same, Lieutenant."

It was plain that the storm soon would be upon them and all haste was made to prepare for the blow. The tents were laid flat, weighted with such equipment as might be expected to hold them there, and the Overland Riders stood or crouched a little fearful in this new mystery of the desert.

"Getting closer!" announced the guide.
