Dec 13 1880 — I have been looking at old pasture land near Leith Hill. In ditch recently dug across part — mould everywhere 8 inches — so it was on a level crest — I begin to believe that mould often first portion is added to with extreme slowness, for worm burrowing seldom to the greater depth, & possibly they may use old burrows, the deposit sand, then castings, though I have never seen this, except in near surface in lower & dug ground.
