Great reforms are seldom accomplished over night. They are usually the outcome of a slow but unfailing evolution due to prolonged educational effort, sometimes coupled with the vigorous enforcement of new measures. By reason of the gradual appearance of the changes brought about, evidence of actual reforms is often difficult to secure when it is sought at too frequent intervals. This is likely to lead to discouragement at times, unless the searcher takes occasion to let longer periods of efforts at improvement pass in review so that the total accomplishment can more readily be envisaged.
