nough to resist the action of the water, that we owe the 
ae of these higher plateaus in the midst of the surround- 
ing waste, where the land has been ground down and swept 
away by rivers and floods for ages; and no doubt the harder — 
and more durable Waterstones above referred to have assisted 
in preserving them from destruction. 
As to the nature of the soil traversed in the excursion, there 
is but little to say. At Misterton—the station before that of 
Haxey, from which our start was made—we passed over an 
_ exposure of the Upper Keuper, in which ‘thin flaggy sandstones 
with red and green Marls’ are laid down in the ‘ Surve 
Leaving Haxey Station, our route lay for some distance over 
sand and gravel, which, as we approached the higher land, gave 
place to Blown Sand, and this alternation of beds continued all 
round the elevated ground—Blown Sand fringing its higher 
slopes, and gravel and sand, with here and there some marshy 
peat deposits covering up the base. 
This Blown Sand, which forms a very interesting character- 
istic feature of this part of Lincolnshire, is derived from the 
low-lying lands on the west, whence the sand is carried by the 
force of the prevailing winds on to the higher ground, where it 
is laid down in drift-banks, dunes and hillocks. This process is 
still going on at the present day in many parts of the district. 
The hamlets of Park and Upperthorpe, through which we 
went, are built on exposed Marls surrounded by this Blown 
Sand. At Skiers Flash, where the peat beds are about four feet 
thick, and at other places we passed by, the Marl is visible in 
the drain bottoms. Beyond this, after crossing the sand and 
aes and the Blown Sand as before, we arrived at Epworth 
the top of the Keuper Hill; and on leaving it, as we 
approached Low Burnham, a fine section of the massive 
Riad Si 
The wer of the way continued on the Keuper Marls to 
Haxey village, where, descending the hill, we got on to the 
alluvial deposits once more—but this time in reverse order, the 
Blown Sand first and then the older sand and gravel—until we 
reached Haxey Station, our starting-point in the morning.
