In 1925, this was the largest sardine factory on the Atlantic Coast, owned by L.D. Clark & Son. And Eastport was the "Home of the American Sardine," as that is where sardines were first canned in the United States, beginning in 1875. By this time the plants numbered 10. This factory was 250 feet long, employed 500 men and women, and packed 4,000 cases of 100 cans each daily when there were herring.

A weir is constructed each season by pounding in vertical piles, then crossing the piles with long straight sticks, then filling in vertical branches. When fish swim to the weir leader (the straight part that comes out from shore), they are diverted into the pound, where they swim around in circles. The seine net is set inside the weir to catch the herring.
Weir fishing was practiced by Maine's Natives, and was especially popular further east where big tides made putting a "Fence in the Water" relatively easy.
