 depth. The furface of the flow, confifting of heath 

 and coarfe grafs, was torn away in large pieces, 

 which mil lie upon the furface of the new mofs, 

 fome of them from 20 to 50 feet long. But the 

 greater part of the furface of the flow remained, and

 flow or mofs feems to have fubfided about 25 feet*
