"The advisability of putting down an inclined shaft in preference to the vertical type should be carefully considered before a definite choice is made. One, of course, presupposes the existence of a dipping ore body that is to be prospected or developed for subsequent mining. Unless a vein has been previously developed there is no certainty that it maintains the same degree of pitch for any great distance below surfaces. If straight, the proposed inclined shaft may depart considerably from the downward course of the vein with the result, that, at least some of the anticipated advantages of the shaft have not been realized. On the other hand a shaft which changes its dip is apt to prove either very costly in construction or inefficient for hoisting purposes"--Merits and Demerits, page 1.
