The cab had stopped at the top of the Rue Denfert-Rochereau, at a short distance from the former outer Boulevard. A big gray wall stretched out, the frigid façade of a State establishment, and it was through a quiet, simple, unobtrusive little doorway at the end of this wall that La Couteau went in with the child. Mathieu followed her, but he did not enter the office where a woman received the children. He felt too much emotion, and feared lest he should be questioned; it was, indeed, as if he considered himself an accomplice in a crime. Though La Couteau told him that the woman would ask him nothing, and the strictest secrecy was always observed, he preferred to wait in an anteroom, which led to several closed compartments, where the persons who came to deposit children were placed to wait their turn. And he watched the woman go off, carrying the little one, who still remained extremely well behaved, with a vacant stare in his big eyes. Though the interval of waiting could not have lasted more than twenty minutes, it seemed terribly long to Mathieu. Lifeless quietude reigned in that stern, sad-looking anteroom, wainscoted with oak, and pervaded with the smell peculiar to hospitals. All he heard was the occasional faint wail of some infant, above which now and then rose a heavy, restrained sob, coming perhaps from some mother who was waiting in one of the adjoining compartments. And he recalled the "slide" of other days, the box which turned within the wall. The mother crept up, concealing herself much as possible from view, thrust her baby into the cavity as into an oven, gave a tug at the bell-chain, and then precipitately fled. Mathieu was too young to have seen the real thing; he had only seen it represented in a melodrama at the Port St. Martin Theatre.[7] But how many stories it recalled--hampers of poor little creatures brought up from the provinces and deposited at the hospital by carriers; the stolen babes of Duchesses, here cast into oblivion by suspicious-looking men; the hundreds of wretched work-girls too who had here rid themselves of their unfortunate children. Now, however, the children had to be deposited openly, and there was a staff which took down names and dates, while giving a pledge of inviolable secrecy. Mathieu was aware that some few people imputed to the suppression of the slide system the great increase in criminal offences. But each day public opinion condemns more and more the attitude of society in former times, and discards the idea that one must accept evil, dam it in, and hide it as if it were some necessary sewer; for the only course for a free community to pursue is to foresee evil and grapple with it, and destroy it in the bud. To diminish the number of cast-off children one must seek out the mothers, encourage them, succor them, and give them the means to be mothers in fact as well as in name. At that moment, however, Mathieu did not reason; it was his
