By Rudolph Blackenburg.

Report on Existing Conditions with Recommendations to the Honorable Rudolph Blackenburg Mayor. “Our report is addressed to sane, serious minded men and women who desire to better conditions in our own city; it is not addressed to those who take no interest in the subject, who think the least said and done the better, or who flippantly dismiss it.”
