What did Mr. Powers do in response to his pledge?

From the text:

"Since making that promise a week ago I have had a good many things to think of," said the superintendent, "and among them is this: The company gives me the use of this room, and I am going to fit it up with tables and a coffee plant in the corner there where those steam pipes are. My plan is to provide a good place where the men can come up and eat their noon lunch, and give them, two or three times a week, the privilege of a fifteen minutes' talk on some subject that will be a real help to them in their lives."
