Thus I began my systematic though half-bewildered tour of Innsmouth's narrow, shadow-blighted ways. Crossing the bridge and turning toward the roar of the lower falls, I passed close to the Marsh refinery, which seemed to be oddly free from the noise of industry. The building stood on the steep river bluff near a bridge and an open confluence of streets which I took to be the earliest civic center, displaced after the Revolution by the present Town Square.
