Mr. Stombaugh. They were not mercerized.

Mr. Eisenberg. How common is cotton as a fiber, Mr. Stombaugh?

Mr. Stombaugh. Cotton is the most common fiber used.

Mr. Eisenberg. And what about nonmercerized cotton, as to commonness?

Mr. Stombaugh. You would find more unmercerized cotton in use than mercerized, because to mercerize cotton is an added production factor used in cotton.

Mr. Eisenberg. How great a variation do you get in degree of twist?

Mr. Stombaugh. You are referring to between mercerized and un——

Mr. Eisenberg. No; within unmercerized cotton.

Mr. Stombaugh. This would depend on the quality of the cotton and the length of the cotton also.

Mr. Eisenberg. But I mean as samples come across your desk in your office, or as you read about them in books, is there a great variation in twist or a small variation?
