MODEL OF HAYLE HARBOUR. 



was a branch of it, and he now suggested to Mr. Henry 

 Harvey methods for deepening and improving it. A 

 rival company of merchants and engineers, known then 

 as Sandys, Carne, and Vivian, after many fights had 

 recourse to law on the question of the course of a stream 

 which had been changed by alterations during the 

 making of wharfs and channels for ships. 



Trevithick made a model in wood, movable layers of 

 which indicated changes of level caused by workmen at 

 different periods, giving a different course to the river 

 bed. Mr. Harvey's counsel, since known as Lord 

 Abinger and Sir William Follett, complimented Tre- 

 vithick on the facility of understanding the case by 

 reference to the model. The writer having carried the 

 surveying chain, was present at the trial at the Bodmin 

 assizes in 1829. 



" ME. GILBERT, " HAYLE FOUNDRY, September 14th, 1829. 



" Sir, I expected to have seen you before this, but am 

 detained by Mr. Harvey's attorney to settle the Foundry Quay. 

 As I made the drawing and model of the disputed ground, and 

 was examined in evidence in court, it was thought proper that 

 I should be present at the time that Mr. Peters came to deter- 

 mine the boundary line between the two companies. This 

 cannot be concluded for ten days. 



" As I have been so long detained I wish to await your arrival 

 in Cornwall for the purpose of trying the new engine while you 

 are down, and will thank you to inform me when you intend to 



be with us. 



" I remain, Sir, 



" Your very humble servant, 



"KicHARD TREVITHICK."

 to Trevithick's engine more than twenty years before, 1
