By taking into consideration the non-simultaneity of break of all fibers in a bundle, and also the uneven distribution of the applied load in a fiber, Lord's data on fiber fineness, maturity, and bundle strengths at zero and 1/8-in. gauge lengths on 37 cotton samples have been analyzed. It is shown that all cottons have the same ideal strength at these two gauge lengths, and that the zero and 1/8-in. gauge lengths are interrelated. It appears that the fiber fineness alone is able to account for the drop in strength as the gauge length increases to 1/8-in.
