On calling upon Mr. Arnold the next day, we found him in the room at the Mission, with his head bowed upon the table, as though in prayer. Looking up at us with blazing eyes, exclaimed: 'Sir, what is to be done about this?' 'About what?' we asked. 'These poor girls,' he replied. 'I have been thinking and praying, and praying and thinking over it all night, but I can see no light. Sir, (pressing his head between his hands,) I shall go mad.' There are about forty dance-houses in Mr. Allen's neighborhood; that is to say, within a half mile square, of which No. 304 Water street is the centre. The average number of girls in each of these houses, the season through, is ten, making four hundred in them all. So that, to feed this half mile square of infamy requires eighty fresh girls per annum. To feed the entire city, requires an average of two thousand one hundred and ninety-four a year, _which is a trifle over six a day, Sunday included!_ Six fresh girls a day from the Sabbath-schools and virtuous homes of the land, to feed the licentious maw of this metropolis of the western world. THE WATER STREET REVIVAL. The result of the publication of Mr. Dyer's article, was to centre upon John Allen an unusual share of public attention. Certain clergymen in the city, thinking the occasion a proper one for endeavoring to create a religious awakening amongst the worst classes of the city, determined to endeavor to induce John Allen to abandon his wicked ways, and lead a better life, hoping that his conversion would have a powerful influence upon his class. They went to work. On the 30th of August, 1868, John Allen's house was closed for the first time in seventeen years. A handbill posted on the door, contained the following announcement: THIS DANCE-HOUSE IS CLOSED. "No gentlemen admitted unless accompanied by their wives, who wish to employ Magdalenes as servants." On the next day it was announced that Allen had abandoned his infamous vocation, never to resume it. In order to do justice to all parties, we give the following, which states the case of the originators of the revivals in their own words. The paper is signed by J. M. Ward, M.D.; Rev. H. C. Fish, D.D.; Rev. W. C. Van Meter; A. C. Arnold; Rev. W. H. Boole; Rev. F. Browne; Oliver Dyer; Rev. Isaac M. Lee; Rev. Mr. Huntington. The facts are as follows:
