BIBBY LINE. ] Meantime other continental nations were awakening to the advantages of steam navigation. On the 30th May, 1817, there was launched at Seville the ROYAL FERDINAND, the first steamer built in Spain. And, about the same date, Mr. Wesewelodsky, a man of great wealth, and owner of several rich mines in Siberia, built two steamers for navigating the River Kama. These vessels were 51 feet and 100 feet long, respectively. Mr. Wesewelodsky travelled with his steamers from his mines to Casan, a distance of 1,000 versts, and accomplished the voyage in 105 hours. [11]“England owes to David Napier the establishment of deep-sea communication by steam-vessels, and of Post Office steam-packets. As a first step, he endeavoured to ascertain the difficulties to be encountered. For this purpose he took passage at a stormy period of the year on a sailing packet, which formed one of a line, and the only means of intercourse between Glasgow and Belfast; a passage which often required seven days to accomplish what is now done by steam in as many hours. The captain of the packet found a young man, whom he afterwards knew as Mr. Napier, during one of his winter passages to Belfast, constantly perched on the bow of the vessel, fixing an intent gaze on the sea when it broke on the side of the ship, quite heedless of the waves and spray that washed over him. He only ceased from this occupation at intervals, as the breeze freshened, to ask the captain whether the sea was such that it might be considered a rough one, and, when told that it was by no means unusually rough, he returned to the bow of the vessel and resumed his study of the waves breaking at her stem. When the breeze began to freshen into a gale, and the sea to rise considerably, he again enquired of the captain whether the sea might now be considered a rough one, and was told that as yet it could not be called very rough. Disappointed, he returned again to his station at the bow, and resumed his employment. At last he was favoured with a storm to his contentment, and when the seas, breaking over the vessel, swept her from stem to stern, he found his way back to the captain and repeated his enquiry, ‘Do you call it rough now?’ The captain replied he could not remember having faced a worse night in the whole of his experience, a reply which delighted young Napier, who muttering, as he turned away, ‘I think I can manage if that is all,’ went down to his cabin. Napier saw
