jygi. Mr D'oivnie''s chart/. 2-2^ 



The fiftiing banks upon the coast, the sunk rocks ana sands^ 

 Hot formerly noticed, and the ftielvings of the fhore^- 

 were first pointed out to his notice by the fifliermen on 

 the coast, from whom he took every pofsible information ; 

 they were tiien ascertained by himself, for the most part,, 

 by actual soundings and surveys. I have seen these surveys,, 

 and, without pretending to a profefsional fkill in matters 

 of that kind, but trusting to the approbation, as to accura- 

 cy, of those who are knowing in these matters, who had 

 examined and approved of them, I can safely say that I> 

 havesLcnno hydrographical chart, those of the Ganges and 

 Baramputer, by major Rennel, alone excepted, that gave 

 such a clear and distinct idea of the surface of the ground 

 below the water near the coasts, 



" This^work he dividers into four charts. The first is a ge- 

 neral chart of the east coast of Scotland, from Holy island 

 and the Staples to I^uncanfby-head, containing the true posi- 

 tion of the fhore, the form extent, and depth of water oa 

 the fiihing banks, with the depth between them and the 

 fliore. In the vacant spaces are charts of the harbours 

 of Aberdeen, Montrose, and Cromarty, on a larger scale. 



" II. A chart of the coast of Scotland, from St Abb's head 

 to the Red-head, in which the Edinburgh Frith is con- 

 tinued up as far as Aberlady bay, and the river Tay, up t3 

 Dundee, on a scale of above half an inch to a mile ; in this-. 

 chart the Cape or Bell rock, and tlie Carr rock, are exactly 

 aid down, with conspicuous land marks for avoiding each j 

 the depth of water on the outjide of the Bell rock, and 

 between it and the fliore, as also the depths near the 

 Carr, off the mouth of the Frith, and in St Andrews bay, 

 are carefully inserted, for a guide to fliips pafsing in th< 

 n'ght or in thick weather *.
