Nov. 10th 1877

Worms

After very violent rain & strong wind, the castings on lawn seemed blown over to leeward, but Horace suggests that part of appearance may be due to the windward side having been washed down. He suggests splashes with mud wd be carried to leeward, bits have soil I think too adhesive. On steep bank below Terrace walk the castings have I think certainly slided much down hill.

Horace asks what wd be effects of subsidence of solid mass of larger of mould on hill side as holes collapse, we know not whether as is probable they go in vertically to vegetable mould or to centre of Earth.

Nov. 12 On steep bank below Terrace I think certainly some castings have flowed downwards.
