#&$=:~.¨¨¨ ¨¨¨.~:=$
##&$=:~.¨¨ because the low friction between the ¨¨.~:=$#

¨¨¨¨¨¨¨¨¨¨ there will be trees on the side of the ¨¨¨¨¨¨¨¨¨¨
¨¨¨¨¨¨¨¨¨¨ rails, but not too close, or they will ¨¨¨¨¨¨¨¨¨¨
¨¨¨¨¨¨¨¨¨¨ be cut down by the railway janitors. ¨¨¨¨¨¨¨¨¨¨
.¨¨¨¨¨¨¨¨¨ there will be plains, and bodies of ¨¨¨¨¨¨¨¨¨.
