A view down the river Welland showing a vessel and in the distance a building with a large chimney that would be the Holbeach Road, Hunt & Jennings Steam Bone Mill (Artificial Manure Manufacturers & Bone Chrushers) (Bones had been imported post 1815, both human and inhuman from the battlefields of Europe, all of the places where the principal battles were fought have been swept alike of the bones of the hero and horse which he rode and thence forwarded to the bone grinders for the purpose of reducing them to a granulated state for the farmer to manure his land). Part of an account from ‘The Observer’ 18th November 1822. I found two vessels had arrived in Spalding with bones from Hamburg in 1848 & 1851 in shipping records.
