The coal bin sat in the basement like a cage. Wooden slats nailed together to make a box and the box held coal and the coal heated the building. Every tenement had a coal bin. The coal bin was the gas tank of the nineteenth century. The coal bin was the battery before the battery.

The coal man came once a week. He backed the truck up to the cellar door and the chute went through the door and the coal slid down the chute and hit the bin and the sound was thunder in the basement. The whole building shook. You knew the coal man was here the way you knew a train was passing. The coal delivery was the heartbeat of the block in winter.

My father shoveled coal from the bin to the furnace every morning at five. The shovel was the alarm clock. The sound of metal on coal woke the building. He said the trick was to keep the fire steady. Too much coal and the building was a sauna. Too little and the pipes froze. The coal bin was not storage. The coal bin was a negotiation between warmth and waste.

The coal dust got into everything. Into the walls. Into the clothes. Into the lungs. The coal bin turned the basement black and the black never came off. You could paint over it and the black came through the paint. The coal bin left a stain on the building that outlasted the coal. The basement remembers what heated it.

They converted to oil. Then gas. The coal bin was emptied and the bin became storage. Christmas decorations. Old furniture. The ghosts of warmth. Some buildings still have the coal bin in the basement. Empty. Black. The wood still smells like sulfur if you put your nose to it. The coal is gone but the bin keeps the memory. The building does not forget what kept it alive.
