ON FOSSILIFEROUS DRIFT DEPOSITS AT KIRMINGTON, LINCOLNSHIRE. 273 
to 3 inches at a depth of 15 feet. It was found necessary to line the 
boring with tubes throughout. 
The section seen in the brickyard and proved in the borehole was as 
follows :— 
Surface soil (at 95 feet above O.D.) J 
Clay with foreign stones (see NoTH A) . : . 
Well-worn shingle, principally of battered flin‘s . : : 
Laminated warp with estuarine shells, and at its base a thin 
seam of peat associated with a sandy warp containing 
freshwater shells in one part of the pit (see NoTE B) mil 3) 
Clean yellow sand, with pebbles of chalk and flint 4 ee 
Red clay passing downwards into tough reddish-brown clay 7 
Purple clay, streaked with silt and loam, passing downwards 
into tough purple clay with small stones including some 
erratics (see NOTE C) . 0

Note A.—Among the erratic stones which this clay contains the following were 
identified: Basalt, porphyrites, rhomb-porphyry, grits, &c. 
Nore B.—Mr. Clement Reid records from this bed Serobicularia piperata, Rissoa 
ulve, Tellina balthica, Cardiwn edule, Mactra subtruncata, Mytilus edulis, and 
abundant foraminifera (see ‘Mem. Geol. Survey, Holderness,’ p. 58). 
Mr. Reid has examined the plant remains obtained by the Committee 
from the band at the base of the warp and reports as follows: ‘The 
plant remains obtained by Mr. Stather from the peaty warp belong to the 
following species :— 
Ranunculus sceleratus, Linn. Atriplex ? 
Bupatorium cannabinum, Linn. Zannichellia pedunculata, Reichb. 
Aster Tripolium, Linn. Scirpus setaceus, Linn. 
Lapsana communis, Linn. a maritimus, Linn. 
Mentha aquatica, Linn, i sp. 
Labiate (wuch crushed) Carex incurva, Lightf. 
‘The list is a small one, but it indicates estuarine conditions, and 
suggests a sub-arctic climate. With one exception the plants are still to 
be found in the neighbourhood of the Humber ; but one of them, Carex 
incurva, is a sea-coast sedge not now ranging south of Holy Isle. 
‘A striking peculiarity of the deposit is the abundant remains of the 
estuarine sedge, Scirpus maritimus, a plant which, growing out of a few 
inches of water, tends to form a thick belt through which few drifted 
seeds would find their way. In view of the abundance of this sedge in 
the bed now examined and of the like-growing reed, Phragmites communas, 
in the deposit which I searched some years ago, the small number of 
other plants yet detected is not surprising. Land plants are only repre- 
sented by two fruits of Zapsana, perhaps brought by birds. These fruits 
of oa as well as those of the sea-aster, are considerably smaller
