In other cases the remains of the gangways or bridges connecting the settlements with the shore have been discovered, but often the village appears to have been accessible only by canoes.
Gangways are left between adjoining rows of tanks, and an overhead travelling-crane facilitates the removal of the electrodes.
Cars may thus be run through long adits or through branch gangways to some central point for making up into trains.
It is also advisable to wash all woodwork and gangways annually with a weak solution of formalin, or other inodorous germicide.
Reducing the risk to health and safety - no more blocked gangways!
