A. By boarding up the front end to make it as near air tight as possible
and using a barrel or a petticoat pipe in place of the stack, wiring it
fast to the smoke-arch. Where a portion of the stack is inside the
smoke-box the engine might steam without the barrel or petticoat pipe.

90. Q. What should be done if the frame is broken between the main
driver and cylinder?

A. Either give up the train and come in light, or disconnect the engine
on that side and come in with reduced tonnage, depending on how badly
the engine pounds when working steam.

91. Q. If the frame is broken back of the main driver?

A. Do not disconnect and do not try to pull a heavy train; it is safer
to come in with light tonnage.

92. Q. In case of broken side rods, what should be done?

A. Take down the broken rod and corresponding rod on the other side of
the engine.

93. Q. What can be done if the intermediate side rods were broken on a
consolidation engine having the eccentric on the axle ahead of the main
wheel?

A. In this case the engine must be towed in. It is possible when the
main pin is broken, so that all rods on one side are taken off, to leave
the rods up on the other side and move the engine with her own steam,
