The vegetable matter (No. 3) in this section was very soft and 

 spongy, easily pierced by the boring-tool, and quite unlike that found 

 in any of the pits or bores made on the shore, which was particularly 

 difficult to bore through ; in fact No. 3 is more like the soft peaty 

 deposit which occupies the flat ground in St.-Bees valley. Two 

 years ago a great length of drains was cut in this peaty matter ; 

 and I had then a good opportunity of ascertaining the nature of it. 

 It, however, was nothing like the vegetable matter which occurs on 

 the shore, being much more spongy, and containing a far larger 

 quantity of water, and altogether having more the appearance of peat, 

 which in fact it is. The vegetable matter on the beach contains very 

 little, or almost no water, notwithstanding that it is covered twice 

 every day by the tide. Another difference between the two deposits 

 is that the one on the shore is quite laminated, whilst that in the 

 valley is totally devoid of lamination. About eighteen months ago 

 Pow Beck, during a freshet, diverted its course just where it passes 

 on to the shingle of the beach (see Section A B, fig. 13). In the 

 new course a large patch of peaty matter, similar to that in the 

 valley, was exposed. After seeing that, I had no doubt whatever 

 that the vegetable matter found in borehole No. 2 was the same, and 

 not at all like that found on the shore. 



Maryport Deposit. — About halfway between Allonby and Mary- 

 port, and about one third of the range of the tide from low-water 

 mark (PI. III. fig. 1), there is another vegetable deposit ; but it 

 is not very well exposed. 



I have not dug through this deposit, and therefore cannot say 

 what is below it ; and the soft silt, which covers the shore in 

 the neighbourhood, prevents any information on that head being 

 obtained. It has the same external appearance as all the other 

 deposits, besides being laminated and very much more compact than 

 peat. It contains a large number of seeds about the size of gun- 

 shot, and a quantity of rush-like leaves, as well as pieces of hazel 

 and alder wood. The wood is in every case flattened as if by 

 pressure. 



There is another and similar deposit about a quarter of a mile 

 further on the shore towards Allonby ; but only the upper surface of 

 it can be seen. Near Beckfoot, I am told, there is another ; but that 

 I have not yet visited; nor have I seen one which occurs at Cardunock, 

 on the Sol way. 



All the deposits described, whether on the sea-shore or inland,
