Scanned from a print in my possession. Unfortunately here is no information regarding the event written on the reverse side of print. Perhaps the pontoon/ferry landing is heading for a scrap yard?
This is the River Tyne Port Sanitary Authority isolation hospital that was berthed on the Jarrow Slake. Built by Wood, Skinner in 1886. I think the photo shows it/her being towed away for scrapping in 1930.
