138 Notes—Lepidopiera and Coleoptera. 
Hogsthorpe, containing a bed of hard, greyish silt, full of stones ; 
and those who were present at the first excursion of the Lincoln- 
shire Naturalists’ Union at Mablethorpe in 1893, will remember 
coming across a disused brick-pit near the coast at Theddle- 
thorpe, where stones were seen imbedded in the unworked clay 
on the pit sides, while a boulder of considerable size lay on the 
margin. This pit was thought at the time to belong to the 
boulder clay, and I so recorded it in a note after the meeting, 
but on reference to the Memoir and Map, I see that this was an 
error, and that the clays in it belong to the higher ‘post-glacial’ 
beds. 
These are two cases bearing on the question, and no’ doubt 
many others will be found when proper search for them is made. 
It will be interesting to add that on one occasion I picked up 
on the shore near Sutton, at low tide, a polished, oval, flint 
instrument, the surface of which is nearly covered by an incrust- 
ing Polyzoon (Membranipora lacrotxiz Hincks). This relic may 
have belonged to one of the old-world hunters in the submerged 
forest which once grew on this part of the Lincolnshire coast; 
the trees of which, extending for miles—some of them prone on 
the ground, and others with their broken trunks still standing 
where they grew—may be seen, skirting the shore when the 
tides are low.
