"Never mind; we'll trim the mixed outfit after we get more of the bunch out," answered the cowboy, riding back into the herd.

While doing the cutting out the men also drove out the few cattle that had strayed into the herd earlier in the journey.

For three hours this grilling work had kept up, the perspiring cowboys yelling, their ponies squealing under the terrific punishment they were getting from both riders and steers.

But in the excitement of their own work, the Pony Riders had had little time in which to observe what the cowmen were doing.

Tad thought of a plan by which he might assist them further. So he galloped his pony over to the edge of the main herd and waited until the foreman dashed out with two red, fighting steers, which he gave a lively start on their way to join the mixed herd.

"Mr. Stallings, may I cut back some of the Diamond D animals in the mixed herd?" he asked.

"Think you can do it, kid?"

"I can try."

"All right. Go ahead. Be careful that you don't turn back any of the other brands, though. Above all, look out for yourself."

Tad galloped back to his companions, his face flushed, the dust standing out on his blue shirt, turning it almost gray.
