(This was a linguistically `stripped` attempt
to poeticise the natural wonder of a canal
lock using an un-literate personna...I hoped
someone else might have had a go at it.......
How about now?)

canal-boat nudge
into hill
not budge

 

nose
into tall slot
back-gate close

 

 

water spill
from top
slot fill

 

boat
up and up
float

 

at top
of hill
boat stop

 

man shout
gate open
boat go out.

 

miracle?...Yup!
water come down
boat go up
