engineering assistance and instruments, to enable the Engineer to make any inspection 

 or measurement connected with the work. Templates for special surfaces, such as 

 the hollow quoins, must be cut out of zinc or galvanized iron, to be provided and shaped 

 by the contractor. 



63. Employees. The contractor will be required to employ a sufficient number 

 of capable and efficient employees who have had experience in the class of construc- 

 tion which they are to superintend. Any person employed by the contractor who, 

 in the opinion of the Engineer, is incompetent, disobedient, disorderly, or otherwise 

 unacceptable, shall at once be discharged by the contractor, at the request of the 

 Engineer, and shall not again be employed on the work. 



64. Machinery. The contractor will be required to employ a sufficient number 

 of appliances suitable for carrying on properly all portions of the work. 



65. Use of U. S. Ground. The contractor will have the privilege of using, during 

 the progress of the work, subject to the approval of the Engineer, any portions of the 

 land to which the United States has title on both sides of the river at the site (for stone- 

 yards, temporary buildings, etc.), which are not used or reserved by the United States. 

 It is understood, however, that the contractor shall, at any time during the progress 

 of the work, promptly vacate and clean up any part of the Government ground that 

 may have been allotted to, or been used by him, whenever such part is needed for 

 any purpose by the United States. The contractor shall keep the grounds and all the 

 buildings within the United States limit, which are occupied or used by himself or his 

 employees, in a cleanly and thoroughly sanitary condition. He will not be allowed to 

 rent or assign to other parties any buildings erected on the United States' land without 

 the permission of the Engineer. 



66. Work on Sundays, etc. In cases of extraordinary emergency, to be deter- 

 mined by the Engineer, work on Sundays or legal holidays may be required. With 

 this exception no Sunday work will be permitted, except for repairs to plant and work 

 of similar nature, nor will any night work be permitted which requires the presence 

 of an inspector. 



67. Failure to Prosecute or to Protect Work. The contractor shall use such methods 

 and appliances for the performance of all the operations connected with the work 

 embraced in these specifications as will secure a satisfactory quality of work and such 

 rate of progress as will, in the opinion of the Engineer, insure the completion of the 

 work within the contract time. If at any time the contractor shall refuse or fail to 

 prosecute the work, or to provide for carrying on the same as directed by the Engineer, 

 or fail to protect properly any part of the work, permanent or temporary, the Engineer 

 shall have power to employ men, to purchase or otherwise provide materials, tools, 

 machinery, etc., and to put the work in proper advancement or condition, and the excess 

 of cost of doing so shall be deducted from payments to be made under this contract.
