The great national work was opened to the public on Wednesday last, with all the ceremonies befitting such an important occasion. The Duke of Wellington, Mr. Huskisson, Sir R. Peel, Prince Esterhazy, and Mr. Holmes were guests of the Committee, together with almost every person of consideration in the neighbouring counties. The project of establishing a correspondence by railway between two of the most populous and important towns in the kingdom, was not started till 1824, when a Mr. James proposed it. The rate of travelling is spoken of as being likely to average about sixteen or eighteen miles an hour. Several of the passengers of the Northumbrian got out to walk on the railway, and among them was Mr. Huskisson. He was discoursing with Mr. J. Sandars, one of the principal originators and promoters of the railroad, when the Rocket engine came slowly up, and as the engineer had been for some time checking its velocity, so silently that it was almost upon the group before they observed it. In the hurry of the moment all attempted to get out of the way. Mr Huskisson hesitated, staggered a little, as if not knowing what to do, then attempted again to get into the carriage. As he took hold of the door to do this, but the motion threw him off balance, and before he could recover he was thrown down directly in the path of the Rocket. Mrs. Huskisson, who, along with several other ladies, witnessed the accident, uttered a shriek of agony, which none who heard will ever forget.
