After placing two kinds of linen tapes at a certain interval and setting them not to sag, the writer examined the error(-)made by elongation by means of operating the tension(0.5~7kg) in the gradual decrease and the gradual increase, and also counted the error(+) caused by the sagging, illustrating each of the errors. The proper using method of linen tape can be shown by seeking the relations between the length of span and tension when these two cancel each other.
