Mr. STOMBAUGH. I would say no significance at all as far as the sole identifying characteristic goes, whether or not this cotton of this cotton has the same twist. The twist we use is for identification purposes only, supplementing other identifying characteristics. Mr . EISENBERG. That is the only purpose I am interested in. Mr . STOMBAUGH. Yes; that is the only purpose. Mr . EISENBERG. But in getting to that, how valuable is it for identification purposes? I am curious as to how many--how much a twist can vary. As you pick up a random fiber, and put it under your microscope, I am interested in how much the twist can vary. For example, if there are only two possibilities, then it isn't too helpful that you get a match in twist, but if there are great variations in twist in cotton fibers as they come under your microscope, it would be helpful in making your identification. Mr . STOMBAUGH. I see what you are getting at. There are great variations. Sometimes in a cotton fiber, the twist will be rather far apart. Other times it will be rather close together. This piece---- Mr. EISENBERG. So that the fibers, the cotton fibers, to begin with, matched in twist, that is, the cotton fibers you found in the paper bag matched the twist of the ones that are contained in the blanket, and you said they also matched in color? Mr. STOMBAUGH. Yes, sir. Mr. EISENBERG. I would like to ask you the same question as to color that I asked you as to twist. How many different shades do you think you can distinguish under the microscope in a green cotton? Would the range be just 2 or 3 different shades, or do you think you could distinguish between 20 or 30 different types of green cotton if you laid them next to each other under the microscope? Mr. STOMBAUGH. No; the range in green cotton fibers, for that matter in any color, is tremendous. This could go to 50 sometimes 100 different shades which you can distinguish under a microscope. To the naked eye, it would look as if it is just green. But you could take, say five different fabrics of the same type that have been dyed exactly the same color or rather you think they are the same shade, and put the individual fibers under the microscope and there will be a big difference noted in shades. Mr. EISENBERG. Now were the green cotton fibers in the blanket uniform as to shade between themselves? Mr. STOMBAUGH. No; these varied. Mr. EISENBERG. To what extent? Mr. STOMBAUGH. They go from a green to a very pale green. Mr. EISENBERG. So that the---- Mr. STOMBAUGH. Might be seven or eight different shades. Mr. EISENBERG. So when you say there is a match, you mean the green cotton fibers you found in the paper bag were within the spectrum of shades that are laid out in the green cotton fibers from the blanket--is that correct?
