Lucius Quintus Cincinnatus Lamar, Henderson Bridge Company v. McGrath…
“ The deeper you go, the harder the earth is to work.' Outside of the testimony of the witnesses, it is manifest that to dig earth on a surface rolling and broken, as the profile shows the surface to have been in this instance, for the sole purpose of constructing a level embankment, and without regard to the depth or extent or level of the pits thereby made, is a very different problem from the digging with the double view of the construction of such an embankment, and the making of a continuous ditch with prescribed directions and uniform bottom level for a length of more than four miles. ”
