If the clam industry is not properly cared for, it will be totally ruined before many years. The clammers do not realize this, because of a mistaken impression that nature will forever furnish them with good clamming, and they have little thought for the future; while, on the other hand, the consumer is indifferent from lack of knowledge.
Scope of the Report.—The object of this report is to present in brief form the condition of the clam fishery in Massachusetts. For this purpose facts showing the present extent of the industry have been compiled, with the view of furnishing both the clammer and consumer with certain desirable information.
The report will consider: (1) general conditions of the industry of 1907; (2) a survey of the clam-producing area, illustrated by maps; (3) a plan of clam culture which will make productive many acres of barren flats; (4) the history of the clam industry, a comparison being made between the industries of 1879 and 1907; (5) a description of the industry.
Methods of Work.—The same methods as used with the other shellfish were pursued in obtaining the statistical data for the clam industry. The clam-producing areas were examined and the observations recorded. Town records, which were of some assistance with the other shellfish, furnished practically no clam data, compelling the Commission to rely upon the estimates of the clammers and clam dealers. While this method made it difficult to secure accurate detailed information, the statistics for each town were checked up in a variety of ways, thus furnishing as nearly correct figures as can be obtained.
In making an historical comparison of 1879 and 1907, the report of Ernest Ingersoll on the clam fishery of the United States, and the report of A. Howard Clark on the fisheries of Massachusetts, as published in the United States Fish Commission Report, Section V, volume 2, and Section II., respectively, were of great use, as practically all of the statistics for 1879 were obtained from these two reports.
In making the survey of the clam areas, records were made of: (1) soil; (2) food (a) in water, (b) on surface of soil; (3) rate of currents; (4) abundance of clams and localities of set; (5) barren flats that can be made productive. In the present report only the kind of soil, abundance of clams and area of barren flats will be given, the food problem being reserved for later publication.
Summary.—In the following summary the seacoast towns are arranged in geographical order from north to south. The number of men includes both regular and intermittent clammers who dig for the market; all others are excluded. In determining the production of any town it is impossible to obtain exactly correct figures, as the amount dug for home consumption is an unestimable quantity, and the clams are marketed in a number of ways, rendering it almost impossible to get complete statistics. The production statistics have been obtained in a variety of ways, and the final estimates have resulted from careful consideration of all facts. The invested capital includes the clammer's outfit and boat, but does not include personal apparel, such as boots and oil skins.
The clam flats are divided into two main divisions: (1) productive; and (2) barren. The barren areas are those where at present no clams grow at all, not even scattering; and areas yielding even a few clams are still considered productive flats, though to all practical purposes barren. It was necessary to make the division thus, as otherwise no decisive line could be drawn. The barren flats are divided into those sections that can be made productive and those that can never be made to grow clams. The productive flats, on the other hand, are divided into areas of good clamming and areas of scattering clams which do not support a commercial fishery. The normal production of the clam flats has been carefully estimated, in view of the previous experiments of the Fish and Game Commission, and the different classes of flats have each been given a certain valuation in computing the total for each town. The areas given of the clam flats are based upon calculations, as no engineering survey was made.
The price of clams varies in different localities, and chiefly depends upon the quality of clams and the method of marketing. In certain towns clams are "shucked" (removed from the shell),—a process which greatly increases their market value; while in other places they are sold only in the shell. These two facts account for the apparent variation in the value of the production in different localities, as each town is given its own market price.
