The Bass River Bridge. The fishing in its many branches not proving as lucrative as formerly, the young men sought employment elsewhere, and in 1870 the population was 3,269; in 1880, 3,288; and in 1885 it had decreased to 2,923. During this time many of the Cape industries were abandoned as unprofitable.
Fishing continued to be the principal industry of the town for three quarters of a century. In 1889 the fishing and coasting vessels registered from Dennis had a total tonnage of 6,955. The fertile Atlantic and other waters have furnished broad maritime fields of labor in which Dennis has increased its wealth and importance more than in agriculture, but during the past twenty years the bogs of the town have been redeemed for the cultivation of cranberries, and the town now has a high position in this branch of industry. The town still had in 1889 over sixty vessels of various tonnage, including nine three-masters, engaged in the coast and fishing trade. History of Barnstable County, Massachusetts Edited by Simeon L.
