There is located on 19th street, New York city, a large establishment devoted to the obtaining and preparing of infants for 'adoption.' This Temple of the Innocents is presided over by a Madam P----, and combines with the features common to the establishments elsewhere referred to, the new and novel feature of a 'nursery' in which the innocents are kept, nursed, and clothed, after a fashion, until they are 'adopted.' The babies are housed in a large and airy room, plainly but neatly furnished, and are attended by a corps of nice-looking nurses. Each babe has its own cradle, and a rattle or toy or two, and the little creatures are really well attended to, as it is evidently and directly the interest of Madam P----to have her stock in trade as healthy- looking as possible, in order to dispose of them rapidly and to advantage. Madam P----is a stout brunette, gaily dressed, and has made a great deal of money by the practice of her peculiar 'profession.' She possesses a large wardrobe of baby-dresses, in which the infants are attired when 'presented,' in order to look as captivating as possible; and the lady is a thorough 'artist' in her way. She has been 'assaulted' by the papers, and 'interfered with' by the police, but, nevertheless, the facts are stated as we have found them. "Another institution, located near that portion of the metropolis denominated Yorkville, is of a much more nefarious description. Here children are left by their unnatural parents to be 'disposed of,' and 'disposed of' they are--not killed outright, but neglected--given to suspicious characters, to mere strangers, and never heard from or thought of afterwards. A pensive-seeming, expressively-faced young woman clad in black, with a shawl thrown over her person, is engaged occasionally to appear as 'the mother'--'the poor, heart-broken mother' of the babies. By her appearance and well-feigned tears, she excites the sympathies of such ladies (few in number) as visit the establishment in good faith for the purpose of 'adopting' infants, and her bursts of maternal tenderness and grief when imprinting a 'farewell kiss, forever' upon the lips and cheeks of her departing darling, seldom fail to draw an extra fee from the benevolent pocket of the 'adopting' patron." Many mothers offer their children for adoption, simply to get rid of the trouble and expense of supporting them. Others part with them with tears and heart pangs, in the hope that the little one's future will be bettered by the change. Various causes are assigned for such acts. AN INCIDENT.
