"Q. 8. Have you in mind--if so, you may state as near as you recall--the rate of increase of any number of those which you have looked up and remember, giving their titles, if you recall them; and, if not, in general?--A. The sales of some of the pieces have doubled within the last two years--double what they were for the four years previous. I have traced up about 20 pieces of that sort to get these figures from which I stated the comparison above. I know when I desire to get new music for my family I call on the operator or performer of some of the stores that handle the music rolls. They often give me a list of the pieces. I usually purchase that. I have a list in my pocket of perhaps at least 20 pieces that I have been recommended to purchase. They have been recommended to me by one of the young men who has charge of that department--music rolls--in one of the stores; pieces I had never heard before. "Q. 9. I understand you mean by your last statement that the pieces that you are recommended to purchase are so recommended by persons who have opportunity to hear them played by means of the perforated rolls?--A. Yes, sir. "No cross-examination." "WALTER LUTZ, witness, called on behalf of defendant, being duly sworn, deposes and testifies as follows: "Direct examination by Mr. BURTON: "Q. 1.

Yes; I have had people come in the store and ask for music which they had heard from the various players. "No cross-examination."
