I used a post-hole auger west of London and it was great. The soil was

I borrowed it again and used it in Essex; utter waste of time. The
soil was sandy and gravelly, the auger wouldn't drill and the holes
collapsed. I found a long trenching spade to be easier.


+1. Auger is normally OK except in very sandy gravelly soils.

Precisely how do you use an auger through a layer of clay with many
massive embedded flints? Your exception clause is woefully inadequate, I
fear.
