The dog, called Prince, was an (26) intelligent animal and, a slave to Williams. From morning till night, when Williams was at home, Prince never left his sight, practically (27) ignoring all other members of the family. The dog had a number of clearly (28) defined duties, for which Williams had (29) patiently trained him and, like the good pupil he was, Prince lived for the chance to (30) demonstrate his abilities.
      Williams was an engine driver. Over the years Prince got to know when his master would leave the house and return, and the dog did not waste this (31) knowledge. If Williams overslept, as he often did, Prince (32) barked at the bedroom door until he woke, much to the (33) annoyance of the family. On his return, Williams’ slippers were brought to him.
      A curious thing happened to Williams during the snow and ice of last winter. (34) One evening he slipped and fell on the icy pavement somewhere between the village and his home. He was so badly shaken that he stayed in bed for three days; and not until he got up and dressed again did he discover that he had lost his wallet containing over fifty pounds. (35) The house was turned upside down in the search, but the wallet was not found. However, two days later --that was five days after the fall--Prince dropped the wallet into Williams’ hand.  (36) Very muddy, stained and wet through, the little case still contained fifty three pounds, Williams’ driving license and a few other papers.
