If any keeper of a ferry shall fail to perform any of his duties under the two preceding sections, he shall forfeit to the county $10 for each day during the continuance of such failure. If such failure be continued for the space of three weeks, or if the ferry shall be abandoned, disused or unfrequented for the space of six weeks, the county board may, on complaint, notify the proprietor thereof to show cause why his license should not be revoked, and the county board may, if the cause is proved to their satisfaction, revoke such license.
