Personal log, 169 p. + blanks at the end, with printed headings to the red ruled columns. Bound in spring back ledger style in half calf. The binding is worn on the spine ends and edges but strong. The wear is consistent with its daily cross-channel use. Page size 28.7x25.3 cm. Signed and dated on the front end leaf ‘C. N. Cobb T S Invicta 1908’ Written in ink in a single legible hand and recording his service on railway ferries Invicta, Riviera and Victoria. Most runs were the scheduled Dover-Calais-Dover or Folkestone-Boulogne-Folkestone sailings with occasional variations. The log shows that these early turbine powered vessels consistently made the crossing in under an hour, a timing comparable to the modern (but larger) ferries. The log covers the whole of the WWI period when the ferries were regularly employed in troop movements. It also notes events like the ferry Onward seen burnt and temporarily scuttled in Folkestone Harbour to douse the fire (p. 162) and docking for repairs. Invicta (built 1905 1,680 tons) was sold in 1923, scrapped in 1932. Riviera (built 1911, 1,674 tons) was requisitioned by the navy in 1914. She was converted to become one of the first aircraft carriers, picking up and lowering her seaplanes by crane. She was only returned to the railway in 1920. Victoria (built 1907 1,689 tons) later spent many years in the ownership of Isle of Man Shipping Company and was scrapped in 1957. Loosely inserted are several items of ephemera including his Registration Card under the 1918 Registration Act, two photographic shipboard portraits of Cobb in uniform and an undated printed tide table for the month of December.
