Succeeding previous report on "Tying Strings" and for the same purpose and test subjects stated therein, actual performances in wringing a handtowel were studied. During a test to perform the wringing at subject's discretion, two photographs were taken for analysis of manual postures respectively at the start and finish of the motion. Only one subject, a 6th grade girl, showed standard performance while those who performed nearest to the standard were 14% with increase according to the advance of grade. The rest of performances were varied and 6% of the total failed to perform the wringing.
