But its convenience in defining legislative districts is obvious.

_To make justice cheap and accessible._ It is well in many ways, as we have seen, to have in every town, village, and city, courts of limited jurisdiction.

But to _establish justice_ in any generous or satisfying sense there should be within the reach of every citizen a court competent to try _any_ difference between individuals regardless of the amount in controversy, and able to punish any crime against the laws of the state.
To bring such a court within the reach of every one was the original reason for the establishment of the county, and remains today the greatest advantage derived from its existence.
Establishment .-- Counties are established by the state legislature.
In thinly settled parts of a state the counties are much larger than in the populous parts.

A county should be large enough to make its administration economical, and yet small enough to bring its seat of justice within easy reach of every one within its boundaries.

In the ideal county a person living in any part thereof can go to the county seat by team, have several hours for business, and return home the same day.
County Board .-- The administration of county affairs is in the hands of the county commissioners or supervisors.
