ORSBRIDGE, Lieut. Philip. A Survey of the Mouth of the River Humber and Spurn-lights, as intended to be erected is most humbly presented to Sir George Saville, Bt....April 1764. Manuscript chart of Spurn Head, ink and wash, on paper, 550 x 760mm.

An interesting series of charts drawn up for the Trinity Corporation of Kingston upon Hull. The problem of erosion and deposition of sand on Spurn Head, and the shifting sands on the estuary, made navigation particularly difficult. The 1764 chart shows one of the earlier 1761 Spurn Head lights washed away. (4)
