Castor
Castor is one of Lord Saltash's two ancient pointers which are the Viscount's nearly permanent companions. While barred from certain rooms such as the breakfast room and drawing room, they will nonetheless lay with their noses over the threshold and slowly try to sneak more of their bodies inside the room.
When the Viscount is in his study or the gun-room, or the estate office, his presence may be located by the rather asthmatic breathing of the aforesaid pointers. One or other of them is generally to be found asleep with its head resting somewhat heavily on his Lordship's foot.
