In 1895 legislation was passed relative to the proper definition of the boundaries of grants. This was rendered necessary because of the haphazard methods hitherto pursued in giving grants with very indefinite boundaries. Mean low-water mark was fixed as the shoreward boundary of grants, while mean high-water mark was defined as the limit to which shells might be placed to catch the set. This, however, was dependent upon the owners of the adjacent property, and their consent was held necessary before this territory between high and low water could thus be utilized. In 1901 special legislation was passed, restricting the catching of oysters in contaminated waters except for bait. In 1904 authority was granted to proper officials to develop the oyster industry by planting shellfish, or by close season. In 1905 the Fish and Game Commission was authorized to expend a sum not exceeding $500 per annum for the investigation of the oyster, by experiment or otherwise, with a view to developing the industry. The development of the oyster laws has been by a process of evolution. They have kept pace with the growth of the industry, and have been in fact the logical outcome of that expansion. The various acts which go to make up the bulk of this legislation have been passed from time to time to fill the immediate demands of the hour, and consequently lack that unity and consistency which might otherwise characterize them. Changing conditions have called for alterations in the legal machinery, as the industry has expanded, to meet new requirements. These additions have frequently been dictated by short-sighted policy, and the Commonwealth as a whole has often been lost sight of in the welfare of the community. Of all the shellfisheries, the oyster industry is most hampered by unwise legislation. It is the most difficult to handle, because it presents many perplexing phases from which the others are free. Clams, quahaugs and scallops flourish in their respective territories, and legislation merely tends to regulate their exploitation or marketing. With the oyster, however, other problems have arisen. The areas in the State where oysters grow naturally are few in number and relatively of small importance. The clam, quahaug and scallop grounds are to be compared with wild pastures and meadows, which yield their harvests without cultivation; while the oyster grants are gardens, which must be planted and carefully tended.
