Half Hitch
THE BLACK WALL
The Black Wall, known by many as the chair hitch, is used by the Steeple Jack while working in the chair up or down; stopping to rest or work, reach through the rope of your chair, grab the fall line by the right hand, pulling it through between yourself and the rope of your chair. At the same movement turning the rope from left to right making a loop in this movement, reach up and set it on the hook of the block at the chair; while doing this reach with the left hand and hold your four lines tight together. This prevents you from going down while making the Black Wall or chair hitch, as it is commonly known.

TANKS, TOWERS AND STANDPIPES
Water tanks, water towers or water standpipes are an easy matter to work on as far as the rigging is concerned, but not as much money is to be made as on smokestacks, church steeples and flagpoles. Nevertheless, they are worth soliciting.
Take, for instance, a water tank. A water tank consists of only the tank itself sitting on a flat roof or ground. Water tanks vary in size.
