They have been known to conquer lions; and yet, while they possess the most indomitable strength and courage, they are the gentlest of animals, suffering children to sit upon them, pull them roughly, and small dogs to snap and snarl at them. Confinement alone disturbs their temper. They are excellent guardians, and such is their deliberate coolness, that they have been known to walk quietly by the side of a thief without doing him an injury, merely preventing his escape. They will, however, suffer the rogue to go away, if he has not already purloined anything. It is well known that dogs love to be in a crowd of people, and this is frequently the temptation for them to enter churches. A number of dogs, in a village of Bohemia, had followed this practice, including an English mastiff, belonging to a nobleman who lived there. A magistrate who presided at a Court, observed upon it, and said, in an authoritative voice, "No dogs shall be allowed to go to church, let me not see one there in future." The mastiff was present, and seemed to listen with attention, not without effect, for on the ensuing Sunday, he, rising early, ran barking at the village dogs, took his station near the door of the church, killed the only dog that ventured in, notwithstanding the prohibition; and always posted himself as a sentinel on duty, before the church, but without ever afterwards entering it. An English gentleman, some time ago, went to some public gardens, at St. Germain, with a large mastiff, who was refused admittance, and the gentleman left him in the care of the bodyguards, who were placed there. The Englishman, some time after he had entered, returned to the gate, and informed the guards that he had lost his watch, telling the sergeant, that if he would permit him to take in the dog, he would soon discover the thief. His request being granted, the gentleman made signs to the dog of what he had lost, who immediately ran about among the company, and traversed the gardens, till at last he laid hold of a man. The gentleman insisted that this person had his watch; and, on being searched, not only his watch, but six others, were discovered in his pockets. What is more remarkable, the dog took his master's watch from the other six, and carried it to him. This is rather an old story, but it is an excellent example of the sagacity of the mastiff. The following anecdote has been sent to me while writing the above, by the gentleman who witnessed the occurrence, and, as Glaucous was half a mastiff, I insert it in this place:-- "An Irish gentleman, possessed a couple of immense dogs, male and female, half Newfoundland, half mastiff, which were celebrated for their sagacity, courage, and high-training. They were, in the most comprehensive sense, amphibious, and their home being near the sea, they spent many hours daily in the water.
