'' At three o'clock as arranged , M. Vulfran rang for Perrine and they drove off in the phaeton to make the customary round of the factories , for he did not let a single day pass without visiting the different buildings . Although he could not see he could at least be seen , and when he gave his orders it was difficult to believe that he was blind ; he seemed to know everything that was going on . That day they began at the village of Flexelles . They stayed some time in the building and when they came out William was not to be seen .
