Construction of the upper section of this railroad, be-side the rapids and to the top of the high bank in NiagaraFalls, was much more difficult and tedious. South of theold Buttery Elevator, at the terminus of the first yearswork, began almost vertical cliffs, extending from the topof the escarpment to the seething rapids below. Drillsand men were lowered over the cliffs to the first ledge,about ioo ft. above the grade line, and blasting operationscarried on mostly by hand. The blasts were fired usuallyat noon, when hugh quantities of rock were thrown into
