In the city the sharp contrast between labor and recreation increases without doubt the appeal of the city to many. The factory system not only satisfies the gregarious instinct, it also gives an absolute break between the working time and the period of freedom. In so far as labor represents monotony, it emphasizes the value of the hours free from toil. This contrast is often in the city the difference between very great monotony and excessive excitement after working hours. It has been pointed out often that city recreation shows the demand for great contrast between it and the fatigue of monotonous labor. So great a contrast between work and play--monotony and freedom--is not possible in the country environment. In the midst of country recreations there are likely to be suggestions of the preceding work or the work that is to follow. It is as if the city recreations were held in factories. Country places of play are usually in close contact with fields of labor. Often indeed the country town provides the worker with very little opportunity for recreation in any form. In rural places recreation cannot be had at stated periods. Weather or market conditions must have precedence over the holiday. Recreation, therefore, cannot be shared as a common experience to such an extent by country workers as is possible in the city. Since the rural population is very largely interested in the same farming problems, even conversation after the work of the day is less free from business concerns than is usually that of city people. The difficulty of obtaining sharp contrast between work and play in the country no doubt is one reason for the ever-present danger of recourse to the sex instinct for stimulation. One source of excitement is always present ready to give temporary relief to the barren life of young people. Not only of the girl entering prostitution may it be said that with her the sex instinct is less likely "to be reduced in comparative urgency by the volume and abundance of other satisfactions."[10] The barrenness of country life to the girl growing into womanhood, hungry for amusement, is one large reason why the country furnishes so large a proportion of prostitutes to the city. "This civilizational factor of prostitution, the influence of luxury and excitement and refinement in attracting the girl of the people, as the flame attracts the moth, is indicated by the fact that it is the country dwellers who chiefly succumb to the fascination. The girls whose adolescent explosive and orgiastic impulses, sometimes increased by a slight congenital lack of nervous balance, have been latent in the dull monotony of country life and heightened by the spectacle of luxury acting on the unrelieved drudgery of town life, find at last their complete gratification in the career of a prostitute."[11]
