still intact. As a brace to the south wall it is ])lace(l iidvantagcously. 

 In excavation, nndcrpinnin^, and lillinfi in the conliactois have 

 exceeded tlie limitiitions i)rcscribed in the contract, and have therelore 

 performed an anioiuit of work for the remuneration of which there is 

 no provision. The following table shows the amount of work am hoi- 

 ized in each of the four items witli reference to which the contract was 

 drawn and the amount actually performed by coutractors:

From this it will be observed that, taking the rate of compensation 

 provided for in the contract as a basis, the coutractors have performed 

 work in excessof that authorized to the aniountof $6.38 [*li37J. Tiiey are 

 fully advised th.it there is no provision for the payment of this excess. 

 The requirements of the contract are, in my opinion, fully met in the 

 quality of material used and the work performed. 



The preservation of iheruin is incomplete. There are six places where 

 liutels have disappeared and not been replaced and a corresponding 

 number of cavities that should be tilled. Deeji seams have been cut 

 in the walls by the action of the elements, and unless far gi'eater jiro- 

 visioii is made i'or its jirotection the work already done will be of small 

 avail. 



At iTiany iilaccs where the debris came in contact with the wall dis- 

 integration seems to have resulted. At a slight touch it frequently 

 crumbles. Owing to this fact two sections of the wall fell during the 

 progress of the work when the d(''bris was removed — one from the east 

 wall, des(M-ibed above, and one from the south wall near the west 

 extremity. These breaches may be observed as shown in two of the six 

 accomi)anying photographs [plates cxx, cxxij. These photograi)hs
