Won.DE'T Break—The testpug of the tena city of the suspension rods for the Petersburg bridge was an interesting experiment. After the rod had borne the full test of the vast weight without breaking, all the pig iron about the establishment waa piled on it, and stlß it held. This is pleasant to know when people have to go over the bridge. It is projier in this connection to say that the delay in the construction of the bridge arises from the failure ol the sub-contractors to sup ply the timber. Mr. Strong has made arrange ments for prompt delivery In future, and now that it is under the charge of able engineers, it win go on rapidly.
