This fact probably explains why common vegetable mould, which has all passed through the bodies of worms is not commonly acid, as far as I have observed. But in one part of my lawn, which part is not well drained & when moss & daisies chiefly grown grow, the mould was distinctly acid. I presume that decomposition of the humus acids had been here checked by air not having had free access
