_Scope of the Report._--The object of this report is to present certain information concerning the scallop industry which will be of use to the scallop fishermen, and of interest to the general public and the consumers. While the scallop is well known as an article of food, the majority of people know little about the animal. It will therefore be necessary in the following report to give brief descriptions of the various methods used in the capture of this bivalve, in order to make clear the more technical portions. The first part of the report considers the general results of the survey, the history of the industry, the scallop laws, the methods of scalloping and the statistics of the industry. The second part gives a more detailed description, the following points being considered under each town: (1) survey; (2) statistics of industry; (3) town laws; (4) history. _Methods of Work._--Several difficulties stand in the way of procuring exact information concerning the scallop industry, especially in regard to historical data which should show the improvement or decline of the fishery. The town records are incomplete, lost, or furnish but slight information. Little has been written about this industry, and we were thus forced to rely upon the scallopers for information concerning the history and former production of each town. Fortunately, the scallop industry is of recent origin (thirty years), and the information is very nearly correct. By the use of town records, market reports, records of express shipments, personal surveys and estimates by the various scallopers, and by all other methods at our command, the facts of the last few years have been obtained in an approximately correct form. The area of the scallop territory was obtained by personal inspection and calculated by plottings on the maps. In designating the area suitable for scallops in any town by a certain number of acres or by plottings on the map, it does not mean that scallops are found each year over all this territory. Allowances must be made for the uncertainty of the scallop supply. Some years there will be no scallops; in other years, plenty. Even when scallops are plentiful, they rarely cover the whole territory, but are found only in certain parts in different years. The designation of an area as scallop territory means that scallops have been found in the past over this territory, and that the natural conditions of the territory appear favorable for scallops. _The Decline._ The most important questions which first come to mind when considering the scallop industry of to-day are these three: (1) Has there been any decline in the industry? If so, how extensive? (2) What are the causes of the decline? (3) How can the fishery be improved?
