"Yes. Ride and ride hard. Even the lazy burros have got to get a move on. We must ride all night to-night, and when day dawns we must be in or near Forty-Mile Canyon. Then let those pirates find us if they can. They will find us sooner or later, in all probability, but by that time we shall be doing some stalking on our own account. You see, they will be expecting to find us here in the morning, but we shall be far on our journey by then," said the guide.

"What! Ride all night?" demanded Emma. "I'll die! I surely will."

"And probably all day to-morrow," nodded the guide. "I will start the Chinaman on his way the moment the sky becomes overcast, and we will follow an hour or so later. You folks will have that much longer to sleep. Good-night, folks." Hi got up abruptly and walked away to give his orders to Ping Wing.

THE WARNING

"Turn out!" It was Hi Lang's voice that summoned the girls from their tents, and a far from welcome summons it was, for they were sleeping soundly.

"Lieutenant, the ponies are saddled and ready," said the guide, halting at Hippy's tent. "Please give the Riders the tent equipment to carry and assist them to lash the stuff on. Everything else has gone forward."

"All right, old ma-an. Can't give me five minutes for a cat-nap, can you?" begged Hippy.
