1) For 'landstaithe'.
There are several examples of ‘stay’ as a form of ‘staithe’ in minor place-names. The comon stay in Bawtry was said by Smith to derive from an Old English word for ‘pool’ but it abutted on the River Idle and seems certain to have been the common staithe. Staithgate in North Bierley is known as Staygate locally and was formerly the way to the coal staithes. The word ‘land-stay’ appears frequently in connection with bridges about the time that ‘land-staithe’ occurred as ‘land stare’ and it seems to have replaced it. In the 1579 contract for the building of Elland Bridge this spelling occurred several times, most relevantly in a reference to the foundations of the said jewels and landstayes. More explicitly, a report on the bridge at Conistone in Wharfedale in 1684 mentioned the excessive charge of new Oake Timber of which they made Fraimes for Lying under the Pillers and Landstays. The flood that destroyed Cam Gill Bridge in Kettlewell in 1686 left part of the landstayes … standinge but in danger to be carried away by the violence of the streame. Timber remained an important bridge-building material: 1708 Charge of wood for the Landstays wearing, Bolton Bridge but no doubt parts of the abutments were already of stone.
