At that time Grady exhibited a piece of soap which contained an impression of a key-hole in the lock of the Adams Express car.

In the course of the conversation which ensued at that time, Grady said that there were two messengers who looked after the Adams Express cars alternately, one on each alternate night.

He said that the most careless of the two messengers was named Moore, and that his evenings from New York were Tuesdays, Thursdays and Saturdays.

Grady said he thought any one of those evenings would be the best to select for the purpose of committing the robbery.
"Some time afterward, on a night when Moore had charge of the express car, I got on the train at Forty-second street, and went into the smoking car.

There was a man there busy making a fire in the stove, and in a few moments Grady came into the car, and in order to signalize to me who Moore was, slapped the man on the back, saying, 'Billy Moore, you don't know how to make a fire.' "The place which I selected as the proper point for throwing off the safes was between Coscob Bridge and Stamford.
