Where is Hewetts Burn?

[stanmapstone]

From the OED Staithe; A landing-stage, wharf; esp. a waterside depôt for coals brought from the collieries for shipment, furnished with staging and shoots for loading vessels.
Etymology: in districts where Scandinavian influence is strong, the word probably represents (or has coalesced with) the cognate Old Norse stǫð feminine ( < *staþwō) landing-stage

The OED really has "shoots" ?   It may be a southern affectation,  but I would normally write "chute"  for any kind of sloping hole that I shovel stuff down.

[stanmapstone]

From the OED. Chute;  A steep channel or enclosed passage down which ore, coal, grain, or the like is ‘shot’, so as to reach a receptacle, wagon, etc. below. In England, usually shoot.
Etymology:  Here there appears to be a mixture of the French chute fall (of water, descent of a canal lock, etc.), and English shoot n.1 The former appears to have been adopted in North America in sense 1, and the application gradually extended to include senses which originate with shoot n.1, and are still commonly so spelt in England.
