They raced madly toward the house. Bang! A shot rang out, and a puff of smoke came from one of the windows. Nort's hat went sailing away as though it were on a string. Bang! Nort saw the agent's pony falter, then recover and go dashing on. Now they were almost to the house. It had seemed as though one of them surely would be hit, for they were speeding across perfectly open territory and the occupants of the house were firing rapidly.

But, somehow, luck was with them. They reached the porch safely. And just as Hawkins was about to give the signal for Bud and the Kid to attack, he saw something that stayed his hand.

From the rear of the house a volume of black smoke was pouring.

CHAPTER XXIII

A RING OF FIRE

"Wait, Nort!" Hawkins yelled. "Stick close to the house! Get in close! Not the front--this way! This way!"

He pulled his horse over to one side and held him as near the side wall of the ranch house as he could get. Nort followed him, also hugging the wall. In that way they were protected from the bullets of Delton's men.

"See what happened?" the agent exclaimed. "The place is on fire! Now they've got to get out, and they'll run right into our hands. How I hope the Kid has sense enough to stay away and nab them when they come out!"

The smoke was billowing out in huge clouds, now. It was a frame house, and a firetrap if there ever was one. Now the flames licked through, and the boards started to burn as though they had been soaked with gasoline.

"Can you sneak around the corner and signal to Bud?" suggested Hawkins.

"Tell him to stay back. Wonder how in thunder this fire ever got going?"

Nort walked his mount toward the front, still keeping as close to the side of the house as possible. All gun-fire from within the burning place had now ceased, but the boy was taking no chances. There were but two windows on that side of the house, and their rooms were not occupied, so that as long as the ranchers kept hugging the wall they could not be shot at. The firing as they approached had evidently been done from an angle.

Hawkins's horse was prancing wildly about. His eyes were focused upon the tongues of flame that spurted out of the rear of the building.

"They can't stay in there much longer!" Hawkins yelled. "How about their ponies? Know where they keep them?"

"Easy to find out. Let's do it--quick. We ought to get around to where the Kid and Bud are and join forces. Ready?"

Hawkins nodded, and once more the two flashed across the open ground, this time away from the danger zone. But there was no need for such haste, for not a shot followed them.

"The horses!" Nort yelled as he rode up. "Get them, Bud, and Delton won't have a dog's chance!"

"Got 'em!" Bud answered. "Soon as we saw the fire I went to where they had them tethered and led 'em over here. There they are, by that tree.

Say, I wonder who started this thing?"

"What makes you think someone started it?" Hawkins asked, looking at him closely.

"Well, I figure it couldn't set itself--and it's not likely an accident would happen."

"Can't tell--like as not a lamp turned over. Wow, look at that roof go! Where can those birds be keeping themselves? What chance have they got now?"

"Probably trying to put it out from inside. Foolish thing to do, but they know as soon as they come out they're finished. I wouldn't deliberately set the place on fire, but it sure solved our problem for us."

As the fire raged more fiercely, the ranchers looked at each other.

What had happened to Delton? Could it be that he determined to stick it out until the last moment, and risk a horrible death? Surely he must realize that in peaceful surrender lay his only hope.

Suddenly Bud uttered a cry.

"Here comes someone! Out of the cellar! Look!" Running toward them was a bedraggled figure. Clothes torn, face blackened with smoke, it presented a truly pitiful picture. As it ran it waved its arms wildly.

Something in the appearance, or possibly its gesture, caused Bud to exclaim:

"Say, he looks familiar! Kid, Nort--know who that is?"

The boys looked curiously at the wretched man. Now he was almost upon them, and they could see his eyes glaring wildly. He reached them and fell to the ground, exhausted. Bud dismounted quickly and bent over him.

"Get up!" he commanded. "Let's have a look at you!" The man dragged himself to his feet. At a sight of his face, blackened as it was by the smoke, all started back.

"Well, what do you know about that!" the Kid cried. "It's our Mexican cook!"

"What are you doing here?" Nort asked sharply. "You with Delton? Hey?

Tell the truth now or I'll hit you!"

"He can't talk!" Bud protested. "Give him a chance. He's all in.

Come here, Mex." The boy held out his arm and the Mexican seized it and steadied himself. "Were you with Delton?" Bud asked.

The Mexican shook his head negatively. Then he pointed to the burning building and waved his arms wildly.

"Steady up!" Bud commanded. "Take it easy!"

The man took a deep breath and regained control of himself. But his gestures were still inexplainable. After a minute of vain gesticulating the Kid suddenly exclaimed:

"I think I get it! Mex, listen here: Did you set that fire?"

A vigorous nod of the head. The boys looked at each other in surprise.

"What for?"

The Mexican pointed to himself, then held up two fingers. Then he pointed to the house, and shook his fist.

"Be means his brother!" the Kid said. "What about him, Mex? Did Delton get hold of him?"

Another nod, and more furious gestures.

"I see!" cried the Kid. "He means Delton put his brother up to some dirty work. That right, Mex?"

Eagerly the man signified yes.

"And he did this to get back at him. But where is Delton, Mex? Why doesn't he come out? He'll be burned to death in there!"

The fire had eaten its way through to the front of the house and now the whole upper story was ablaze. It seemed impossible that any living creature could withstand those flames.

"Where's Delton, Mex?" the Kid persisted.

The cook pointed to the house then to the ground.

"The cellar!" Bud cried. "He means they're hiding in the cellar!
