There has been for some days much heavy rains & in my field & on field to village shallowy ponds on surface of grass-land. This water is slightly muddy — This may be in part due to castings — notice this of the flowing of old & recent water chalk castings, [Though:] new to case of above muddy water it = of course impossible to say that very heavy rain having not washed away some fine Earth from grass matted land.
