The older brother went through a career of thieving and burglary. We have not an accurate catalogue of his various offenses, but he undoubtedly made away with property--wasted or destroyed it--to the amount of two thousand dollars. [We recall three lads who, in one night, broke into a house in Bond Street, and destroyed or made away with property to the value of one thousand three hundred dollars.] He was finally arrested and tried for burglary. It would be safe to estimate the expenses of the trial and arrest at one hundred dollars. He was sentenced to five years in Sing Sing. Allowing the expenses of maintenance there to be what they are on Blackwell's Island, that is, about twelve dollars and fifty cents per month, he cost the State while there some seven hundred and fifty dollars, not reckoning the interest on capital and buildings; so that we have here, in one instance, the very low estimate of two thousand eight hundred and fifty dollars as the expense to the community of one street-boy unreclaimed. Had the Lodging-house taken hold of him five years earlier, he could have been saved at a cost of fifteen dollars. His brothers have added to the wealth of the community and defended the life of the nation, and are still honest producers. He has already cost the State at least two thousand eight hundred and fifty dollars, besides much immorality and bad example, and he has only begun a career of damage and loss to the city. PREVENTION AND PUNISHMENT COMPARED. Our criminals last year cost this city, in the City Prisons and Penitentiaries, about one hundred and one thousand dollars for maintenance alone. Our police cost apparently over six hundred thousand dollars. The amount of property lost or taken by thieves, burglars, and others last year, in New York city, and which came under the knowledge of the police, was one million five hundred and twenty-one thousand nine hundred and forty dollars; but how many sums are never brought to their notice! The expenses of the arrest and trial of two criminals, Real and Van Echten, are stated, on good authority, to have been sixteen thousand dollars for the first, and twenty thousand dollars for the second.
