Bags of slate (OX14 (Caldecott))

I've got lots of bags of slate! All gathered from a garden area approx 3x5m give or take. It might benefit from being hosed as some of it's really clean while some of it is a little bit muddy.

I'm most of the way through collecting it all from my front garden - but I'm running out of rubble bags. I'll put the rest in trugs and buckets today, so whoever collects will need to think about how to transfer it. To add to that: I'd really like the rubble sacks back after it's been moved. I hope that's understandable and manageable.
