Various works of a more or less imperfect character were carried out, such as the bridging over in 1637 of the Drainage.
It was hoped that the assembly of the attacking troops in the restricted zone opposite the crossing point, the rapid bridging of the dry canal, and the pushing forward of guns to cover the farther advance, and of reinforcements, ammunition and supplies to support it, could all be carried out with the necessary speed and security, although the difficulties to be faced were very great and the possible causes of contretemps numerous.
In 1763 the first North Bridge, connecting the Old Town with the sloping ground on which afterwards stood the Register House and the theatre in Shakespeare Square, was opened; a little later the Nor' Loch was partially drained, and the bridging of the Cowgate in 1785 encouraged expansion southwards.
Thus Ultramontanism is not to be conceived as a theological movement, but as the programme of a party whose principles are in fundamental opposition to modern culture, modern education, modern tolerance and the modern state - a party which seeks to carry out its campaign against the society of to-day, not by bridging the gulf betwixt creed and creed, but by widening it, by awakening religious fanaticism, and by closing the way to a peaceful co-operation of Catholics and non-Catholics in the highest tasks of culture and human civilization.
Now it is well understood that in many positions this system is the simplest and most economical method of bridging.
