Alnmouth Marine Algce. By Andrew Ainory. 267 



Whether Uthyr really was the brother of Aurelius Ambrosias, or whether 

 the latter really was the Nathan Llwycl of the Welsh accounts or not, 

 does not matter to the geography of Uthyr's career; the line he was fighting 

 on would naturally be about the centre of the country, in the hills of York- 

 shire and Selkirkshire. The dates of the Saxon advance westward are 

 tolerably well-known. 



These heroes, Uthyr and Gwynn, are so utterly homeless, such mere 

 wandering phantoms, not even ghosts, in legend and history, that if they 

 once were powers in the land, human entities of great energy and import- 

 ance, it is of no small consequence to history to find anything that fixes 

 their local habitation. The places they should occupy as to date are better 

 known; about a.d. 500 for Uthyr, and for Gwynn about 580. It is not 

 unlikely that Gwynn returned to the south of Scotland when Gwalchmai, 

 that is Gawaine, succeeded his uncle Arawn in Dumbartonshire. 



The name of the Cameron Burn, a very small stream which runs down 

 the south side of Minchmoor, is very suggestive of Cambrian ; and that 

 suggests analogies elswhere ; especially as the name of Wallace's Trench 

 near it is not probably that of the Guardian of Scotland, as poetically 

 supposed by Sir Walter Scott, but that of his paternal race.

 named, by your accomplished member, Edward Batters, Esq., P.L.S., for 

 whose kind assistance I am much indebted.

In the early days of October 1885 we had some rough weather, and an 

 enormous quantity of sea-weed was cast up at Alnmouth. Amongst the 

 bewilderiug mass of beautiful forms torn from the deep, I discovered my
