One afternoon, the commandant of Bathurst was quietly reading, when he heard a violent squeaking and hissing in the room below him, which was even with the ground, and contained stores. He took the key, and followed by his servants armed with sticks, went to ascertain the cause. On opening the door they beheld a rat and a venomous serpent engaged in mortal combat. Nothing could be more beautiful than the action of both animals; the rat had retreated for a moment, and stood with flashing eyes; the head of the serpent was reared to receive a fresh attack; again and again they closed and separated, but the reptile, although much bitten, gained the victory; the rat fell, foamed at the mouth, swelled to a great size, and died in a very few minutes. The serpent glided away, but was afterwards discovered in her nest with several young ones, in a crack of the store-room wall, close to a staircase, which we were in the habit of descending daily, and where, in fact, I had often seen the serpents' heads peeping out, and had waited till they were withdrawn. Of the brown rat Mr. Jesse tells the following story:--"The Rev. Mr. Ferryman, walking out in some meadows one evening, observed a great number of rats in the act of migrating from one place to another, which it is known, they are in the habit of doing occasionally. He stood perfectly still, and the whole assemblage passed close to him. His astonishment, however, was great, when he saw an old blind rat, which held a piece of stick at one end in its mouth, while another rat had hold of the other end of it, and thus conducted his blind companion." The amount of destructive force possessed by rats, cannot be better exemplified than in the report given to the French Government, relating to the removal of the horse slaughter-houses, situated at Montfaucon, to a greater distance from Paris; one great objection being the disastrous consequences which might accrue to the inhabitants of the neighbourhood, if these voracious creatures were suddenly deprived of their usual sustenance. It is well known, that the mischief which they occasion is not confined to what they eat; but they undermine houses, burrow through dams, destroy drains, and commit incalculable havoc, in every place and in every thing.
