This description comes from  "Haney's Base Ball Book of Reference" from 1867 by
Henry Chadwick.

The Model Base Ball Player

This is an individual not often seen on a ball ground, but he nevertheless exists; and as
a description of his characteristics will prove advantageous, we give a pen photograph of
him, in the hope that his example will be followed on all occasions, for if it were, an end
would at once be put to many actions which now give rise to unpleasantness on our ball
grounds.

His moral attributes

The principal rule of action of our model base ball player is, to comport himself like a
gentleman on all occasions, but especially on match days, and in so doing he abstains
from profanity and its twin and vile brother obscenity, leaving these vices to be alone
cultivated by graduates of our penitentiaries.

    He never censures errors of play made by a brother member or an opponent,  as
    he is well aware that faultfinding not only leads to no improvement in the play of
    the one who blunders, but on the contrary is calculated to have the very reverse
    effect.

    He was never known to dispute the decision of an Umpire, for knowing the
    peculiar position an Umpire is placed in, he is careful never to wound his
    feelings by implying that his judgment is weak.

    He never takes an ungenerous advantage of his opponents, but acts towards
    them as he would wish them to act towards himself.

His physical qualifications

    To be able to throw a ball with accuracy of aim a dozen or a hundred yards.

    To be fearless in facing and stopping a swiftly batted or thrown ball.

    To be able to catch a ball either on the "fly" or bound, either within an inch or
             two of the ground, or eight or ten feet from it with either the right or left hand or
         both.

    To be able to hit a swiftly pitched ball or a "slow twister" with equal skill, and
    also to command his bat so as to hit the ball either within six inches of the
    ground or as high as his shoulder, and either towards the right, centre or left
    fields.

To conclude our description of a model base ball player, we have to say, that his conduct
is as much marked by courtesy of demeanor and liberality of action as it is by excellence
in a practical exemplification of the beauties of the game; and his highest aim is to
characterize every contest in which he may be engaged, with conduct that will mark it as
much as a trial as to which party excels in the moral attributes of the game, as it is one
that decides any question of physical superiority.
