Farnham Bishop, Panama, past and present (1916)
“ There are one hundred of these steam-shovels on the Isthmus, and more than fifty of them in the Gaillard Cut, and to see them all purring and rooting together, more like a herd of living monsters than a collection of machinery, is one of the most wonderful spectacles in the world. Sometimes steam-shovels will be caught and buried by a "slide," an avalanche of rock or a river of mud brought down by some weakness in the banks. Wrecking trains and powerful railroad-cranes are always kept ready to go to their rescue. ”
