Mr. Eisenberg.

We are putting in the sack and 364, the 10-day later sample.

Mr. Dulles.

Sack and 10-day later sample. Which is on which side?

Mr. Cadigan.

The Sack is on the left and the replica bag obtained On December 1 is on the right.

Mr. Dulles.

Yes. I find there that the sample obtained 10 days later, and the sack which is on the left, that the sample obtained 10 days later shows a lighter shade of purple than the sack, and that the tape shows a darker shade of, I would call it, almost gray as against almost white for the tape which is on the sack.

Mr. Eisenberg.

I have no further questions, Mr. Dulles.

Mr. Dulles.

Have you anything that you feel you should add, anything in this general field that would help the Commission?

Mr. Cadigan.

No, sir; not as it relates to this paper and these paper bags.

Mr. Eisenberg.

You will be called later for testimony on handwriting--I suppose you will be the person to testify?

Mr. Cadigan.

Whenever you want me I will be available.

Mr. Eisenberg.

Did you examine the tape for microscopic--to determine the morphiology of the fibers in the paper?

Mr. Cadigan.

No.

Mr. Eisenberg.

Can you tell us why?

Mr. Cadigan.

I didn't feel it was necessary.

Mr. Eisenberg.

I wonder whether you could do that, Mr. Cadigan, and send us a letter as to the results?

Mr. Cadigan.

Certainly.
(The letter referred to was later supplied and is set forth at the end of this testimony.)

Mr. Eisenberg.

And also, did you notice how the glue had been applied to the tapes?

Mr. Cadigan.

Yes; you might say glue was applied all the way across the tapes.

Mr. Eisenberg.

There are no discernible differences in them?

Mr. Cadigan.

The glue on the tapes would be applied with a brush at the time of manufacture.

Mr. Eisenberg.

Is there more than one way of applying glue?

Mr. Cadigan.

Oh, yes. On some tapes, if you look at them either before or after they are used you will see a continuous line running right down the tape where they have used a wheel applicator, merely a difference in manufacturing methods.

Mr. Eisenberg.

But you found a brush applicator?

Mr. Cadigan.

Yes.

Mr. Eisenberg.

Will the same manufacturer use two different methods?

Mr. Cadigan.

He might or might not.

Mr. Eisenberg.

In your experience, is it likely that he would use two different methods?

Mr. Cadigan.

I really couldn't say.

Mr. Dulles.

Mr. Cadigan, I thank you very much for your most interesting and helpful testimony.
(Whereupon, at 1:50 p.m., the President's Commission recessed.)

Hon. J. LEE RANKIN,

DEAR MR. RANKIN: During the testimony of Special Agent James C. Cadigan on April 3, 1964, before the President's Commission, Mr. Melvin Eisenberg of your staff orally requested Special Agent Cadigan to make a fiber analysis of
