The third illustration facing page 134 is interesting as representative of a type of coasting steamer introduced about the year 1855. She shows very well the simplest form of an iron ship propelled with a screw, and evinces sufficient resemblance to the dying sailing ship before the steamer had taken on a distinctive character of her own. In a word, here is the steamship not in her crudity, as in the case of the _Clermont_, but certainly in her elementary form without any of those extra decks and houses which were still to come, and which to-day give such distinct personality to the steamship. It will be seen that she is just a flush-decked vessel, with a central protection amidships for her engines and boilers. There is no forecastle, no poop, and in the development of type she stands at the beginning. She was built for the North Sea trade, and in bad weather must have been a singularly wet boat. She was only of 677 tons gross register, and the absence of any shelter would, when steaming to windward in a bad sea, cause her to be swept from end to end. Similarly, her stern being equally unprotected by either poop or quarter deck, she would be at the mercy of a bad following sea. It was not surprising that this elementary type soon gave way to those modifications that we shall see hereafter. In design of her body this present model illustrates again Scott Russell’s system of obtaining a capacious ship combined with the qualities of slipping through the water with the minimum of resistance. This will be especially noticeable by regarding the long straight middle body. She was propelled by oscillating engines, and a two-bladed screw, having also sails on her three masts.
