Rev. E. Adrian Woodrufte- 
Peacock writes :—The soils between Thorne and Crowle are 
most varied. Many of them are purely artificial or of true 
human origin. The rock bed consists of the water stones of 
the Keuper, but it is all buried by sand and gravel of river 
origin, blown sand and peat. Phleum pratense maximum was 
only met with once, on old canal dredgings. MJyosotzs collina 
only as a road-side casual. Mypocheris radicata was con- 
spicuous on the peaty soils, but Crzcus arvensis was only found 
on dyke banks in shallow peat mixture. Chrysanthemum 
Leucanthemum was patchy in the same situation. An oat field 
illustrated what a combination of natives and aliens might be 
found on a rich, peaty, sand, alluvial soil :—Vzola arvensts, 
Spergula sativa, Anagallis arvensis, Lepidium campestre, 
Raphanus Raphanistrum, and Myosotis versicolor, Matricaria 
chamomilla were all found within a yard. A peaty sand 
pasture had the characteristic combination :—Agvostis vulgarts, 
Festuca rubra, Galium palustre, typica, though var. wztheringii 
was the commonest form, Polygonum amphibium, Myosotis palus- 
trts, Potentilla sylvestris, Hieractum Pilosella, Myosotis verst-
