In a late article, we alluded to the prodigious amount of crime and bloodshed perpetrated in this State, and especially in New OrÃÃ©ans. The following article from the N. O. Tropic developes one great reason of this amount of crime - the utÃer ignorance of the mass of the people. No wonder the city needs an armed police. One hundred public scholars in 50,000 people! OÃ¼r Public Schools. - The very excellent public schools of the Second Municipality, were visited last week, by the Mayor of the city, and several intelligent and public spirited Aldermen of the First Municipality, accompanied by our worthy citizenand long and excellent public instructor, Mr. G. W. Harby, Principal of the Public Schools of the Third Municipality, with a view of ascertaining, by actual observation, whether the system adopted for their government, would advantage the First Municipality, in an eftbrt being made there to organize a more efficiÃ«nt system of Public Education; and we are pleased to learn from the respectable visitants, that nothing could be more satisfactory than the excellent state and condition in which they found these useful seminaries.More than one tbousand scholars are now in the Public Schools of the Second Municipality, out of a population of 25,000; while in that of the First, there are not more than 100 out of a population of 50,000!! Surely such a disparity ought not to exist, and we are right glad to know that the important subject has obtained the favorable attention of the ex-Attorney General, and now Alderman Roselius; himself thoroughly convinced of the great wants of his constituents, there is great reason to believe further and important irnprovements in it will speedily manifest themselves under his enlightened and energetic advocac y."
