If it were built on the double intersection principle, the lattices would be double. Engineers take the position that it is much easier to calculate the direct stress on the members of a single intersection than to divide up the strains amongst the members of the double intersection.

As my hon. friend (Mr. Lennox) says, we are not now discussing who was at fault; but we have had one disaster, the most lamentable part of which was the great loss of Mr. GRAHAM.
life. We must provide against anything of that kind in the future. The question of safety might be divided into two periods. There is the question of safety after the bridge is erected-that is one thing that is most essential.
