John, does this help?

You have two sides, one out in the field and one in. Each man that's in goes out, and when he's out he comes in and the next man goes in until he is out. When they are all out, the side that's been out comes in and the side that's been in goes out and tries to get those coming in, out. Sometimes you get men still in and not out.

When a man goes out to go in, the men who are out try to get him out, and when he is out, he goes in and the next man in goes out and goes in. There are two men called umpires who are all out all the time, and they decide when the men who are in are out. When both sides have been in and all the men have been out, and both sides have been out twice after all the men have been in, including those who are not out, that is the end of the game.
