Mr. Stovall.

mapping, and actually all we do is set words, letters, and figures. We have no correlation of what they refer to.

Mr. Jenner.

It's charting of coastal areas, sea bottoms, and some land areas or what?

Mr. Stovall.

Yes; and some foreign areas, too.

Mr. Jenner.

That is, other than continental United States?

Mr. Stovall.

Yes; right.

Mr. Jenner.

Was any of this work done in the department or area to which Lee Oswald had access while he was employed by your company?

Mr. Stovall.

Not in the department at all. Whatever secret work we might have been performing, we do it with the persons who had been cleared by the regular procedures and they are the only eyes who view this. •

Mr. Jenner.

So, anything that is classified is done only by employees of yours who have been cleared by an appropriate Federal agency?

Mr. Stovall.

Yes, sir.

Mr. Jenner.

And then, I gather that as far as Lee Harvey Oswald is concerned, he had no part in it nor access to any of this work?

Mr. Stovall.

This is correct.

Mr. Jenner.

And that your company is at pains to see that no one other than those who are cleared have access to it?

Mr. Stovall.

That is correct.

Mr. Jenner.

And that was true while he was working for you?

Mr. Stovall.

Yes. In fact, at such times as we have any secret work going, even at the point of being rude, we see that no one has access to any of this material. I won't say--rude but we strictly enforce it.

Mr. Jenner.

Well, you make it pretty firm, which is right?

Mr. Stovall.

Right.

Mr. Jenner.

Do you do any lithography work?

Mr. Stovall.

No.

Mr. Jenner.

Do you do any printing of advertisements, papers, newspapers, periodicals?

Mr. Stovall.

No.

Mr. Jenner.

You set type, of course?

Mr. Stovall.

We set type. The only printing we do is a proving process, and that should we do an ad, let's say some of the Savings Bond Committee and ship one hundred mats, we would also ship one hundred proofs.

Mr. Jenner.

You pull off proofs but your presses .are proof presses, and that's all?

Mr. Stovall.

Right; we have no printing presses in this regard.

Mr. Jenner.

I take it you do a lot of camera work?

Mr. Stovall.

Considerable; yes.

Mr. Jenner.

But it is commercial camera work?

Mr. Stovall.

Right;it isn't even photography. It is only the part of reducing and enlarging printed material that we set in our type shop. It has to be re-sized and we also make screen veloxes.

Mr. Jenner.

Explain for the record what that is.

Mr. Stovall.

A velox is a photographic print that has been screened by a dot press to separate the tone values in order that a camera can shoot them in black and white or in any group of colors, but it breaks it down into minute units that a camera will recognize.

Mr. Jenner.

That's like half tones for newspaper printing?

Mr. Stovall.

Right.

Mr. Jenner.

Do you do any plate work other than the mats?

Mr. Stovall.

No.

Mr. Jenner.

Is the term "microdot printing" or lithographing familiar to you?

Mr. Stovall.

Lithography is--microdot printing is not.

Mr. Jenner.

And you don't do any work of that nature and character?

Mr. Stovall.

No.

Mr. Jenner.

Other than the preparation of or use of dot work as you have already described it?

Mr. Stovall.

Yes.
