The following production table does not include an important factor,--the amount of clams dug by the summer people. An unestimable quantity is annually taken from the flats in this way, and is not included in the production statistics. Indeed, summer people have affected the clamming interests of several towns, as the selectmen have refused to place closed seasons, etc., on certain depleted flats in order to cater to the summer residents, who desire free clamming near their cottages. The total number of licenses issued by the boards of health of Boston and New Bedford for taking shellfish in their respective harbors are given as representing the number of clammers. In reality, however, only a few of these licensees make a regular business of clamming.
