The chief clerk’s absence was a vexatious delay. But, though it would hold up his work on the alibi for a day or two, he might begin on one of the other points which had occurred to him during the journey to Paris. There was, for example, the tracing of the carter who brought the cask from the Gare du Nord to the rue Cardinet. He would see what could be done on that. Accordingly he went out to the great Goods Station and, introducing himself to the agent in charge, explained his errand. The official was exceedingly polite, and, after some delay, the two porters whom Burnley and Lefarge had interviewed some weeks before were ushered into the room. La Touche questioned them minutely, but without gaining any fresh information. They repeated their statement that they would recognise the carter who had brought the cask were they to see him again, but were unable to describe him more particularly than before. La Touche then went to the Gare du Nord. He was fortunate in finding the clerk who had handed over the cask to the black-bearded Jacques de Belleville. But again he was disappointed. Neither the clerk nor any of the other officials he interviewed recollected the carter who had taken the cask, and none therefore could say if he was like the man who delivered it at the Goods Station. Baffled on this point, La Touche turned into a café, and, ordering a bock, sat down to consider his next step. Apparently Lefarge had been right to advertise. He recollected from the report he had had from the authorities that all the advertisements had appeared in, among other papers, _Le Journal_. He determined he would see those advertisements in the hope of discovering why they had failed. He accordingly drove to the office of the paper and asked leave to look over the files. A slight research convinced him that the advertising had been thoroughly and skilfully done. He took copies of each fresh announcement--there were nearly a dozen. Then, returning to his hotel, he lay down on his bed and looked them over again. The paragraphs varied in wording, type, and position in the columns, but necessarily they were similar in effect. All asked for information as to the identity of a carter who, about six o’clock on Thursday, the 1st of April, had delivered a cask at the rue Cardinet Goods Station. All offered a reward varying from 1000 to 5000 francs, and all undertook that the carter would not suffer from the information being divulged. After a couple of hours hard thinking La Touche came to the conclusion that the advertising had been complete. He saw no way in which he could improve on what Lefarge had done, nor could he think of anything in the announcements themselves which might have militated against their success.
