MODERN SEAL

Cast lead two-part bag seal, used for flour, made up of two circular discs joined by a rectangular connecting strip with embossed lettering on both discs. The obverse reads: J.H. TREVITHICK & SONS above ROLLER MILLS HAYLE in three lines; and the reverse reads: ONE AND ALL with each of the three words alligned with the outside of an angle of an equilateral triangle, and an 'X' in the centre of the triangle. On one edge there are two smaller rectangular slots for a string to pass through the centre of the seal, and on the opposite edge there is one, larger slot.John Harvey Trevithick (1807-1877) was the second son of Richard Trevithick, the famous innovator, and the grandson of John Harvey who formed the foundry Harveys of Hayle. J.H. Trevithick & Co. had a store, flour and grist mill in Harvey's in Foundry Square, Hayle, as part of the retail trading and milling company that also included the shipping line to Bristol, Cardiff and Liverpool, from 1852. So the seal probably dates from after this time and before 1890 when John Harvey Trevithick's second son Richard (1842-1930) formed a partnership with W. Hosken & Son and J.S. Polkinghorne to become the largest milling firm in Hayle: "
