VEITCH: RAISED BEACHES. 
amongst the vegetable remains. One of these trunks of oak is 
preserved in the Albert Park, Middlesbrough, and when placed there 
it weighed eleven tons. 
Thinking it possible that the deposit might extend inland, that 
is, to the west at Stranton, I obtained the following section from 
borings made in search of a water supply : — 
Boring at the West Hartlepool Ironworks : — Passed through 50ft. of 
gravel and clay before penetrating the new red sandstone. 
Boring at the Seaton Carew Ironworks, half-a-mile to the south of the last 
boring : — Passed through 60ft. of gravel only, before reaching the 
new red sandstone. 
Attention will now be drawn to four sections which will throw 
some hght upon the probable time at which this mass of vegetable 
matter was formed. In clearing away matter to form the central 
dock, at West Hartlepool, the following notes were taken : — 
FEET. 
Gravel ... ... ... ... ... 3 
Peat with numerous trees i/i si^zt... ... ... G to 8 
(This bed thickens towards the timber ponds where it 
becomes 40ft. thick)

We must now go to the Saltholme boring of Messrs. Bell Bros., 
where we have feet.

Passing on to the south of the river Tees to the Middlesbrough 
Graving Dock, there is

A section near Lackenby, beginning 9ft. below high water 
mark, gives 
FEET. 
Sand and Silt ... ... ... ... ... 22 
Blue Clay ... ... ... ... ... 3 
Into Red Clay, no doubt Boulder Clay. 
* It is most probable that the thickening of the bed at this point is due to 
the gradual dissolving and washing out of the permian Hmestone below it during 
the growth of the forest, as it is here that the magnesian limestone crops out 
from under the new red sandstone.
