He laughed again, and his laugh was so infectious that the three laughed with him.

"I know most people in Texas," rumbled the Ring Tailed Panther, "though there are some Mexican families I don't know. But I've heard of the Urreas, an' if you want to go with us an' join in tearin' an' chawin' we'll be glad to have you."

"So we will," said Ned and Obed together, and Obed added: "Three are company, four are better."

"Very well, then," said Urrea, "I shall be happy to become one of your band, and we will ride on together. I've no doubt that I can be of help if you mean to keep a watch on Cos. My horse is tied here in a clump of chaparral. Wait a moment and I will rejoin you."

He came back, riding a fine horse, and he was as well equipped as the Texans. Then the four rode on toward San Antonio de Bexar. They found that Urrea knew much. Cos himself would probably be in San Antonio within a week, and heavy reinforcements would arrive later. The three in return gave him a description of the fight at the mound, and they told how the Texans afterward had scattered for different points on the border.

They were not the only riders that night. Men were carrying along the whole frontier the news that the war had begun, that the death struggle was now on between Mexico and Texas, the giant on one side and the pigmy on the other.

But the ride of the four in the trail of Castenada's flying troop was peaceful enough. About three hours after midnight they stopped under the shelter of some cottonwoods. The Ring Tailed Panther took the watch while the other three slept. Ned lay awake for a little while between his blankets, but he saw that Urrea, who was not ten feet away, had gone sound asleep almost instantly. His olive face lighted dimly by the moon's rays was smooth and peaceful, and Ned was quite sure that he would be a good comrade. Then he, too, entered the land of slumber.

The Ring Tailed Panther stalked up and down, his broad powerful figure becoming gigantic in the moonlight. Belligerent by nature and the born frontiersman, he was very serious now.

He knew that they were riding toward great danger and he glanced at the face of the sleeping boy. The Ring Tailed Panther had a heart within him, and the temptation to make Ned go back, if he could, was very strong. But he quickly dismissed it as useless. The boy would not go. Besides, he was skillful, strong and daring.

The Ring Tailed Panther tramped on. Coyotes howled on the prairie, and the deeper note of a timber wolf came from the right, where there was a thick fringe of trees along a creek. But he paid no attention to them. All the while he watched the circle of the horizon, narrow by night, for horsemen. If they came he believed that his warning must be quick, because they were likely to be either Mexicans or Indians. He saw no riders but toward daylight he saw horses in the west. They were without riders and he walked to the nearest swell to look at them.
