I denies them to be fir trees, suggesting the 
i querie, whether there may not possibly grow 
I trees even under the ground, as well as other 
' thinss. There are in Cumberland, on the 
sea-shore, trees sometimes discovered at 
low water and at other times, that lay 
buried in the sand; and in other mossy 
places of that shire ’tis reported the people 
frequently dig up the bodies of vast trees 
without boughs, and that by direction of 
the dew alone in summer, for they observe 
it never lies upon that part under which 
those trees are interr’d.”^ 
In Cornwall the valleys in and around the 
granite districts, have been carefully examin¬ 
ed for tin pebbles in the process called tin 
streaming. In these lonely barren regions 
the delicate pink heath, (erica tetralix) now 
springs up amidst the mosses, the fairest and 
largest representative of the vegetable king¬ 
dom ; but the traveller who pauses to w atch the 
primitive-looking miners in the stream work, 
may perceive by the side of their excavation.
