A Canadian agent has gone to England to arrange with Peto, Brassey&Co., for the construction of the Trunk line of railway.— The contractors are to get about $40,000 a mile; and the road is to be of a very surperi- or character, with tubular bridges, such as have never been constructed on this conti nent. The Manager ot the Electric Telegraph Company at Glasgow, Scotland,, states that the transmission ot intelligence over the wires was suspended in consequence of an aurora borealis, which prevailed at the time.
