Dark Satanic Exclamation Marks

On the second part of our walk around Halifax in the 1930s, note the snow around Halifax Parish Church (nothing changes, does it?), and the black spire of the town hall punctuating the smoke-stacked atmosphere. And note the mills, as dark and satanic as any Blake poem, punctuating the life of the town, their chimneys creating an endless pattern of exclamation marks.
