Contractors 
	
	1795  
	Contractors John Bosville & Stephen Holland were employed to start at 
	Outmarsh near Semington, to dig out the canal foundations. 
	
	North 
	of Double Bridge, they met William Edwards who had started at Stanley and 
	worked his way south, excavating the locks and basins at Pewsham.
	
	1795 
	– 1799  John Bosville was also a bricklayer, and he was employed with John 
	Smith to build many of the structures:
	
	·      
	
	
	Swivel bridge at bottom of Naish Hill
	
	·      
	
	
	Double 
	Bridge
	
	·      
	
	
	Croker’s Bridge
	
	·      
	
	Three 
	locks at Pewsham
	
	·      
	
	The 
	towpath at Pewsham
	
	By 
	1797, the canal as a navigation had reached Melksham, the locks at Pewsham 
	were well under way, and the company of John Smith and John Bosville had 
	completed Derry Hill Bridge under the Chippenham – Calne Turnpike Road.
	
	
	1797-9  One wall of Pewsham Top Lock had to be pulled down and rebuilt, so 
	£50 was deducted from Smith & Bosville’s account.
	
	1797 
	– 1798  William Large and Joseph Camm were contracted to excavate the 
	Chippenham Arm (‘Ippy Cut’).
	
	
	1799     John Bosville and Stephen Holland puddled the Pewsham Locks and dug 
	out the foundations of the Lock Cottage.
