seeing that I have suffered nothing by contact with it, I suppose no
harm will come to such as listen to the little I have got to say on the
subject.

A benevolent desire to launch far and wide the already well-spread
reputation of the New York rowdy impels the present writer to declare
his conviction, that, should Physiology offer a premium for the
production of a perfect and unmitigated specimen of _polisson_,
Experience would seek for it among the choice representatives of the
class in question,--ay, and find it, too. Nor would the ardor of search
be chilled by the suggestion of scarcity conveyed in the practical
sarcasm of the sly old cynic, when he scorched human nature with a horn
lantern by instituting a search with it on the sun-bright highways for
an unauthenticated type of man. And yet the rowdy, like many another
ugly and repulsive thing, may have his use. In the East Indies, it is
customary to keep a live turtle in the wayside water-tanks which are so
precious in that thirsty land, the movements of the animal, as well as
the industry with which it devours all noxious particles which chance
may have conveyed into the waters, serving to keep them in a condition
of purity and health. The rowdy is the turtle in the tank,--so far,
at least, as being an ugly beast to look at and a great promoter of
commotion,--by which latter service he keeps the community alive to
the presence of impure particles in the social element, if he does not
assist in getting rid of them. An alligator in an aquarium might furnish
a better comparison for him in other respects.

Of this class there are many branches; but the one with which I have to
deal at present is to be studied to most advantage by visiting some pier
of the great river-frontage of New York, to which excursion-boats rush
emulously at appointed hours, crossing and jostling each other with
