This apparatus being then arranged, the engineer, after having sent his companions to a distance, filled the hole, so that the nitro-glycerine was on a level with the opening; then he threw a few drops of it on the surface of the rock, above which the mass of iron was already suspended.
El ingeniero hizo alejar a sus compañeros, llenó la mina de modo que la nitroglicerina sobresaliese un poco de la abertura y derramó algunas gotas por la superficie de las rocas debajo de la maza de hierro ya suspendida.
