Mr. Eisenberg.

the southeast corner of the sixth floor of the TSBD following the assassination, and which, for the record, is a bag which may have been used to carry this rifle, 139, which was used to commit the assassination. 677 is a sample of paper and tape---and parenthetically, tape was used in the construction of 142---677 is a sample of paper and tape obtained from the Texas School Book Depository on November 22, 1963, that is, the very day of the assassination.

Mr. Dulles.

Obtained by whom, by the FBI?

Mr. Cadigan.

This was obtained by the Dallas police.

Mr. Eisenberg.

And forwarded to you by the Dallas----

Mr. Cadigan.

By the Dallas police through our Dallas office.

Mr. Dulles.

It was obtained after the assassination on that date?

Mr. Cadigan.

Yes, sir; the night of November 22
At the same time, on November 23, we had an agent come in from Chicago with samples of paper from Klein's, with the possibility, it was thought, that the paper sack----

Mr. Dulles.

Identify Klein's just for the record.

Mr. Cadigan.

Klein's Sporting Goods Store in Chicago, from which the Italian rifle was bought.

Mr. Eisenberg.

That is Exhibit 139?

Mr. Cadigan.

Exhibit 139. The agent brought in these paper samples from Klein's for comparison purposes, and the paper tape, this manila gummed tape, had these knurl markings measuring 30 per inch.

Mr. Eisenberg.

That is the gummed tape you obtained from Klein's?

Mr. Cadigan.

Yes. It was not identical with this, but merely, you might say, illustrate that the markings will differ depending on the wheel, and if your wheel has 30 lines per inch and your other sample is 24 or 25 lines per inch, you know they didn't come from the same tape dispenser.

Mr. Eisenberg.

Mr. Cadigan, do these wheels differ as to their diameter across the bearing surface, the length across the rolling knurled surface?

Mr. Cadigan.

I imagine there would be a difference.
I have made no precise measurement but I imagine they vary within tolerances of a quarter- or half-inch in width.

Mr. Eisenberg.

Would the length of the lines produced on 142 be the same the paper bag---the same as the length of the lines produced on 677?

Mr. Cadigan.

Yes.

Mr. Dulles.

At what period in connection with the manufacture of the paper are those lines put on or----

Mr. Cadigan.

These are put on after the paper is complete.

Mr. Dulles.

After paper is completely manufactured?

Mr. Cadigan.

Yes, sir; that is right.

Mr. Dulles.

And put on by the dispensing machine?

Mr. Cadigan.

No; the individual buys gummed tape in rolls.

Mr. Dulles.

Yes.

Mr. Cadigan.

Three-inch rolls or inch-and-a-half rolls. He then puts it on a tape-dispensing machine.

Mr. Dulles.

In his particular organization?

Mr. Cadigan.

Yes; or his factory or shipping department or wrapping room.

Mr. Dulles.

I understand.

Mr. Cadigan.

Once it is in that machine then that wheel will mark the tape going through the dispenser just before it wets it and you paste it down.

Mr. Dulles.

Just before, generally just before it is used, then these markings are put on by the dispensing machine.

Mr. Cadigan.

Yes, sir.
After examining the papers, comparing them visually and under the microscope, I examined them under ultraviolet light. This is merely one additional step.
Here again I found that both of them fluoresced the same way.

Mr. Eisenberg.

Could you explain the meaning of that?

Mr. Cadigan.

Yes. Paper, along with many substances, has the property of absorbing or reflecting ultraviolet light rays differently. You can take two
