How long did it usually take to fill the barrel?
At this season of the year one or two weeks.

When was it emptied last?
A week ago, perhaps, the witness was not quite sure about the day, but it was either Monday or Tuesday of the preceding week.

And how often did the ashes from the fireplaces in Mr.North's and Mr.Gilmore's rooms find their way into the barrel?
Every morning he cleaned out the grates the first thing, and usually before Mr.North or Mr.Gilmore were up.
Again Moxlow paused and glanced over the room.

He must have been aware that to his eager audience the connection between Mr.North's and Mr.
Gilmore's fireplaces and the McBride murder, was anything but clear.
"Did you empty the ashes from the fireplaces in the apartments occupied by Mr.North and Mr.Gilmore on Friday morning ?" he asked.
"Yes; that is, I took up the ashes in Mr.North's rooms." "But not in Mr.Gilmore's ?" "No, sir, I didn't go into his rooms Friday morning." "Why was that,--was there any reason for it ?" "Yes, I knew that Mr.Gilmore's rooms had not been occupied Thursday night; that was the night of the murder, and he was at McBride's house," explained the witness.
"But you emptied the grate in Mr.North's rooms ?" "Yes, sir." "And disposed of the ashes in the usual way ?" "Yes, sir." "In the barrel in the yard back of the building ?" "Yes, sir." "Did you notice anything peculiar about the ashes from Mr.North's rooms on Friday morning ?" The witness looked puzzled.
"Hadn't Mr.North burnt a good many papers in his grate ?" "Oh, yes, but then he was going away." "That will do,--you are excused," interposed Moxlow quickly.
The sheriff was next sworn.

Without interruption from Moxlow he told his story.
