An electrical light - there are at least two more in a line in the photo........
Aha!
They are a form of carbon rod arc light called a "Moon Light." They were self-igniting (the fuse that got them started had to be replaced before they could be ignited the next night.)

LIFE EXPECTANCY
Carbon rods in the first Moon Lights lasted two hours.
In the 1890s the carbon consumption of the rods was slowed down considerably by enclosing the lamp in a gas tube, which increased the life expectancy of the carbon sticks fivefold – enough to make the rods last all night.
Later arc lights could burn for 100 to 150 hours (4 to 6 days) without replacing the rods.
