    neutral soap, free from resin, may be used and tlie hemp fiber retted without the use of the acid bath, the fiber being rinsed in soft water. Also the retting will be done in two to three days if the weather is warm, and there will be but little of the bad odor attending ordinary water retting. If this solution of soap and water is made hot, the retting will be done in twelve hours. If perforated steam l)ipes are inserted at the bottom of the tanks or vats and live steam turned in for boiling, the ret- ting will be complete in one to three hours, accord- ing to strength of solution used and the degree of fineness desired. If the hemp which has previousl} been water retted and broken is boiled for half an hour in such a saponaceous solution a uearlj* ])er- fect fiber results. After boiling and rinsing and drying, and the hemp has lain four to six weeks to mellow, ripen and gain nature and quality, it is run through the breaking machine, softened and baled, as is done with cotton.
