The same considerations, both of economy and humanity, apply to each of the results that appear in these tables of crime and punishment. No outlay of money for public purposes which any city or its inhabitants can make, repays itself half so well as its expenses for charities which prevent crime among children. CHAPTER XXXVII. THE CAUSES OF THE SUCCESS OF THE WORK. In reviewing these long-continued efforts for the prevention of crime and the elevation of the neglected youth of this metropolis, it may aid others engaged in similar enterprises to note in summary the principles on which they have been carried out, and which account for their marked success. In the first place, as has been so often said, though pre-eminently a Charity, this Association has always sought to encourage the principle of Self-help in its beneficiaries, and has aimed much more at promoting this than merely relieving suffering. All its branches, its Industrial Schools, Lodging-houses, and Emigration, aim to make the children of the poor better able to take care of themselves; to give them such a training that they shall be ashamed of begging, and of idle, dependent habits, and to place them where their associates are self-respecting and industrious. No institution of this Society can be considered as a shelter for the dependent and idle. All its objects of charity work, or are trained to work. The consequence is that this effort brings after it none of the bad fruits of mere alms-giving. The poor do not become poorer or less self-reliant under it; on the contrary, they are continually rising out of their condition and making their own way in the world. The laborer in this field does not feel, as in so many other philanthropic causes, doubtful, after many years of labor, whether he has not done as much injury as good. He sees constantly the wonderful effect of these efforts, and he knows that, at the worst, they can only fail of the best fruit, but certainly cannot have a bad result.
