Excavation^ levelling, and rejilling. — The trench for the foundation walls 

 of the central building shall be excavated to a depth of four feet six inches,

 below the present surface of the ground, at the centre of the north side of 

 the building. 



The trench for the foundation walls of the principal central front towers 

 and the central rear tower shall be excavated to a depth of eight feet (8 feet) 

 below the above line; and for the campanile, octagonal, and all the lesser 

 towers, to a depth of six feet (6 feet) below the above line. 



The trenches for all the partition and interior walls, and for all the foun- 

 dations under pillars, &c., shall be excavated to the same depth as those 

 for the outside walls Avith which they are connected. 



The earth between the wall trenches, in both wings, both connecting 

 ranges, and the great lecture-room, shall be excavated to a depth of 5 feet 

 below the same line under the whole building. 



The earth between the foundation trenches of all the towers and the 

 space on the north front between the central towers will be excavated to a 

 depth of G inches less than the trenches of the walls. 



All remaining excavation for areas, coal slides, sess-pools, sinks, <fcc.,

 be directed by architect.
