Rh amount of 538,750 francs, for making new boilers for the screw; the second to the amount of 662,500 francs for general repairs, and fixings on board.

Before entering upon the last undertaking, the Board of Trade required that the ship's hull should undergo a strict examination. This costly operation accomplished, a long crack in her exterior plates was carefully repaired at a great expense, and the next proceeding was to fix the new boilers; the driving main-shaft of the wheels, which had been damaged during the last voyage, had to be replaced 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,
