nark

That the "nark," with his mean tricks, is a nuisance to wandering beggars is seen in a very short time.

All true wanderers hate him; even the drunken, domineering grinder is treated with civility in a house where beggars see a "nark."

Another "nark" was a drunken drover, who left a saucepan on the fire while he went out for a drink.

By the way, the sight of a pepper-box in a lodging-house kitchen is always a sure sign that the man behind it is a "nark."

Moreover, a few strokes more would interpose the strange sub chaser between her and the Nark, and whoever was aboard would escape.
