 taken to do the work in a first-class manner. 



Failure to Comply With Specifications.— In case 

 the contractor shall fail to comply with the specifica- 

 tions, or refuse to correct faults in the work as soon as 

 they are pointed out by the person in charge, the em- 

 ployer may declare the contract void, and the con- 

 tractor, upon receiving seventy-five per cent of the 

 value of completed drains at the price agreed upon, 

 shall release the work and the employer may let it to 

 other parties. 



Sub-letting Work, — The contractor shall not sub- 

 let any part of the work in such a way that he does not 

 remain personally responsible, nor will any other party 

 be recognized in the payment for work. 



Plans and Tools. — The contractor shall furnish all 

 tools which are necessary to be used in digging the 

 ditches, grading the bottom, and laying the tile. In 

 case it is necessary to use curbing for the ditches, or 

 outside material for covering the tile where sand or 

 slush is encountered, the employer shall furnish the 

 same upon the ground convenient for iise. 



All plans and figures furnished by the engineer, to- 

 gether with the drawings and explanations, shall be 

 considered a part of these specifications.
