Mr. EISENBERG. The Exhibit Paine No. 2 is tied into a knot at this point. Can you tell us what kind of a knot that is? Mr. STOMBAUGH. This was a simple bow knot which I put into it. Mr. EISENBERG. You put it into it? Mr. STOMBAUGH. Yes, sir. Mr. EISENBERG. So the knot does not reproduce the knots as you found them originally? Mr. STOMBAUGH. No; they do not. Mr. EISENBERG. Mr. Stombaugh, I wonder if you could tie the demonstration piece of string you have been using into the granny knot and bow knot, in the manner in which you received it. Mr. STOMBAUGH. There is the granny knot and here is the bow knot. Mr. EISENBERG. You are not here trying to approximate the diameter or the circumference of the string, but only the knots? Mr. STOMBAUGH. No. Mr. EISENBERG. Mr. Chairman, may I admit this string as an illustrative exhibit? The CHAIRMAN. It may be done. Mr. EISENBERG. That will be 664, Mr. reporter. (The item referred to was marked Commission Exhibit No. 664, and received into evidence.) Now, Mr. Stombaugh, did you examine this blanket to determine its composition? Mr. STOMBAUGH. Yes; I did. Mr. EISENBERG. Can you give us your conclusions? Mr. STOMBAUGH. The blanket is composed of a very small percentage of brown and green woolen fibers; an average of about 30 percent to 40 percent of brown and green cotton fibers, and the remaining portion brown and green delustered viscose fibers. Mr. EISENBERG. When you say "a very small portion of brown and green woolen fibers," could you be more specific; was it in the neighborhood of 1 percent or 10 percent? Mr. STOMBAUGH. I was unable to obtain a definite percentage. This is a rather long, involved, and inaccurate method of determination because one would need a brand new blanket to get a good quantitative analysis. However, in the samples of the fabric that I made, I found approximately 1 to 2 percent woolen fibers, 20 to, I would say, 30, 35 percent cotton fibers, and the remainder of it viscose fibers. This is just an approximation from the microscopic slide that I made. Mr. EISENBERG. Would you have any reason to believe that the approximation was not made from a fair sample of the blanket? Mr. STOMBAUGH. No; I wouldn't. I took the sample myself. However, the blanket is very well worn. Most of the nap has been worn off of it. It has had a lot of use, and much of the original composition has been worn off. Now, whether or not this same percentage of composition is missing from use or not I wouldn't be able to determine, but I would say that the approximation that I had given is fairly accurate for the blanket in its present condition. Mr. EISENBERG. Mr. Stombaugh, could you explain to us briefly how you were able to distinguish the three fibers, cotton, wool, and viscose?
