The stump is gone

Took about two hours in three sessions, quite a lot of digging, the use of both (borrowed; thanks rmc28) axe and mattock, and some blisters on my hands; I'm very thankful that leylandii don't have tap-roots, I'm not sure what I'd have done in that case.

Now all I have to do is fill in the hole where the stump was, and I'll never trip over it again. Is rotting wood a good fertiliser?
