QUEBEC, April 11.--Wholesale trading in young and innocent girls for purposes of prostitution has come to the notice of the authorities. Disreputable houses in Chicago, New York, Boston and other cities in the United States have agents here, who ingratiate themselves with young women and induce them to go to the states, where they are drawn into a life of infamy. The trade has been carried on to an alarming extent, sometimes fifteen girls being shipped in a week. The prices paid to agents depend on the looks of the girls, and vary from $20 to $200. It is stated that over fifty girls have been sent to one Chicago house within a year.--”Daily Press.”
