DUNKIRK GRAVELLY CLAY LOAM. 
The Dunkirk eravelly clay loam is a small type, and 
occurs typically developed near the western border or the 
Dunkirk clay. This soil was formed under lake influence. 
It is a yellow to a light brown loam, four to six inches 
in depth, underlain by a yellow loam changing to silt and 
mottled clay, below which is boulder elay. From fifteen 
to thirty rive per cent of gravel is vresent. the fine 
earth of this soil consists of silt and clay into which is 
mixed a considerable portion of sand and gravel. It owes 
its origin to a set of peculiar conditions in that at the 
Same time that clay was being deposited, sand and gravel 
were also brought in and de »osited. Boulders are rare in 
this type, the stony material being ail rather fine, not 
more than two or three inches in diameter, and well worn 
both by glacial action and by water. 
In color this type is not very unlike the Dunkirk clay, 
but its texture is very different. The soil is rather 
loose, and well drained except in places where the subsoil 
comes very close to the surface. In adaytation it ls 
similar to the Dunkirk clay. Or course it is easier to 
handle, and in its cultivation so much attention does not have 
to be given to determine if it be in right condition. When 
very wet this soil becomes yuite like quiek sand. On side
