In 1878 a peculiar act was passed, making it unlawful for any person to remove oysters from any grant, even his own, between the hours of sunset and sunrise. This act was necessary for the protection of the oyster planters, by preventing the stealing of oysters from the grant at night. Various efforts had been made to protect grants from such attacks, but the extreme difficulty of detection was always an insuperable obstacle to proper enforcement, and it was deemed expedient to prohibit all fishing at night. That this problem had become an important one is shown by the title of the law, which was styled "An act for the better protection of the oyster fisheries in this commonwealth." In 1884 an important act was passed, enlarging the limits of that territory which might lawfully be used for the cultivation of oysters. Practically all communal waters outside the jurisdiction of adjacent land owners was thrown open for oyster grants. In 1885 the institution of a public hearing was inaugurated. This was a concession to the hostile quahaug element, and allowed the public the opportunity of protesting against the granting of territory for oyster culture; nevertheless, the final power really remained in the hands of the selectmen. A further concession to this element was the law which called for the revoking of grants within two years if unimproved. The interests of the oystermen were also kept in sight, and legislation passed which was designed to protect grants still more from the depredations of outsiders. Provision was likewise made for the proper enforcement of these laws, and the penalties attached were increased. In 1886 an act was passed which was designed to do away with all possible outside monopoly. The danger of organized capital acquiring control of a large tract and excluding small individual planters had become apparent, and this means was taken to guard against it. The act prohibited the transfer of grants in any township to any person not a citizen of that township; thus, if any monopoly did exist it would be restricted to only one township. The limits during which fishing on grants might be carried on was lengthened two hours, so that it read from "one hour before sunrise to one hour after sunset." In 1892 the town of Yarmouth obtained a law requiring a permit for citizens to take oysters from native beds, not exceeding 2 bushels per week, from September 1 to June 1. This is now the only town in the Commonwealth to require such a permit from citizens.
