The Contractor, however, will not be required in such cases to excavate the mud or other soft material to a greater *epth than two feet below sub - grade. All filling shall be done with sand or good sound earth. The embankments shall be carried up in horizontal layers, not to exceed one foot each in thickness, and the teams shall be made to travel as evenly as possible over the whole surface of each layer, going and coming.
