Salt marsh hay is still gathered on the North Shore today. The grass that grows between the upland and the marsh is cut. Traditionally the hay was stacked on staddles to raise it above the high tides.
In a northeasterly storm in December, 1786 Samuel Pulsifer and Samuel Elwell of Rowley were digging clams, got caught in the storm, and took refuge in a stack of salt hay for the night. In the morning they found they had been set afloat!
