From VALERIE WALKER
I found your article ‘The physics of muesli’ (26 May) very interesting.
I now understand why, in spite of removing every large stone in my flower
border every time I weed, I find just as many to take their place within
a month. As this has been happening for 15 years, is there hope that I will
not be confronted with yet another crop of stones?
