At Bristol, on Wednesday, an iron bar was thrown across
the Avon,
at the place fixed upon for the suspension bridge. The height from the river was 900 feet. A car was attached to she bar, in which the engineer, Mr. Brunel, was to cross from rock to rock. After the rod had been drawn across, an unfortunate aceident occurred, while the workmen were engaged in fastening it in the rock. By the cutting through of a rope attached to the rod, some scaffolding gave way; and the rod itself fell to the bottom of the river, by which fall it was much bent. One of the workmen was seriously hurt by the fall of the scaffolding. By great exertions the rod was replaced on Thursday, and Mr. Brunel was to exhibit himself in the ear to-day. In the course of Monday morning, Mr. Pocock exhibited several of his cars drawn by kites on Durdliam DOVVII, for the amusement of the savans and a numerous assembly of the Bristolians.
