I tried to stop him by shouting that the Indians were Pawnees and our friends.

He did not hear me, but kept straight on, never stopping his horse till he reached the camp.
I knew he would tell General Carr that the Indians had jumped him, and that the general would at once start out with troops.

So as soon as the Pawnees rode up, I told them to remain there while I rode after my friend.
When I had reached camp, he had given the alarm, and the general had ordered out two companies of cavalry to go in pursuit of the Indians.
I told the general the Indians were only Pawnees, and that a joke had been put up on McCarthy.

I neglected to tell him who had put up the joke.

He was fond of a joke himself, and did not get very angry.
