Mr. Cadigan. I have marked it.

Mr. Eisenberg. Mr. Dulles, would you care to look at it?

Mr. Dulles. And—oh, yes—and they go over a good deal further than your circle?

Mr. Cadigan. Yes, sir.

Mr. Dulles. They run right across.

Mr. Cadigan. I might explain that these are made by a wheel in the paper-tape dispenser. [Referring to an object in the room.] It is not quite this size, but it is similar to this and it has horizontal markings running all around the wheel.

As you pull the operating handle that pulls the paper tape from the roll through the machine and over the wetting brush, the wheel, in the process leaves these markings on the tape.

Mr. Eisenberg. Excuse me, Mr. Cadigan, would this be in the type of tape dispenser which is operated not merely by a handle—by a handpull—to the tape from the dispenser, but is operated—that is operated by a lever?

Mr. Cadigan. Yes; a lever, a handle.

Mr. Eisenberg. And a given quantity of tape is dispensed, which you can cut off or not as you choose—if you want to, you can pull some more tape and cut it off, is that correct?
