Harlson had an odd fad over which we had many a debate.
It occurred usually upon the street cars.

He would make a study of the women in the car when we were together--it seemed to amuse him--and tell me whether they were married or not.

He would not look at their hands--that would be a point of honor between us--but only at their eyes, and then he would say whether any particular woman were married or single, and we would leave it to the rings to decide.
Sometimes he would lose, but then he would only say: "Well, if she didn't wear a wedding ring she should have done so," and would pay for the cigars we smoked.
He had some sort of fancy about their eyes which I could never quite understand.
