by a shaft, provided with two eccentric wheels, which insured the solidity of this important part. And now for the first time the Great Eastern was to be steered by steam.
It was for this delicate operation that the engineers intended the engine which they had placed at the stern. The steersman standing on the bridge between the signal apparatus of the wheels and the screw, has before his eyes a dial provided with a moving needle, which tells him every moment the position of his rudder. In order to modify it, he has only to press his hand lightly on a small wheel, measuring hardly a foot in diameter, and placed within his reach. Immediately the valves open, the steam from the boilers rushes along the conducting tubes into the two cylinders of the small engine, the pistons move rapidly, and the rudder instantly obeys. If this plan succeeds, a man will be able to direct the gigantic body of the Great Eastern with one finger.
For five days operations continued with distracting activity. These delays considerably affected the enterprise of the freighters, but the contractors could do no more. The day for setting sail was finally settled for the 26th of March. The 25th still saw the deck strewn with all kinds of tools.
During this last day, however, little by little the gangways were cleared, the scaffoldings were taken down, the fly-wheel cranes disappeared, the fixing of the engines was accomplished, the last screws and nails were driven in, the reservoirs filled with oil, and the last slab rested on its metal mortise. This day the chief engineer tried the boilers. The engine-rooms were full of steam; leaning over the hatchway, enveloped in a hot mist, I could see nothing, but I heard the long pistons groaning, and the huge cylinders noisily swaying to and fro on their solid swing blocks. The muddy waters of the Mersey were lashed into foam by the slowly revolving paddle-wheels; at the stern, the screw beat the waves with its four blades; the two engines, entirely independent of each other, were in complete working order.
Towards five o'clock a small steamer, intended as a shore-boat for the Great Eastern, came alongside. Her movable engine was first hoisted on board by means of wind-
