Moral and spiritual search-lights are needed to warn and illuminate the
soul, just as the search-lights noted here are used to help the mariner
as he approaches land.
“It has been announced,” says _The Electrical Review_,
“that one of the features of the Lewis & Clark exposition
will be a large search-light surmounting Mount Hood. This
will be used to good effect for illuminating the snow-capped
mountain-peaks within one hundred miles of the light. It is
also said that the beam thrown from this search-light will
be visible to vessels one hundred miles off the coast. This
statement suggests that the search-light might be used as a
valuable aid in lighthouse service, for warning vessels when
they are approaching land. The ordinary range of visibility
of a lighthouse is about twenty or twenty-five miles. For a
lightship it is somewhat less, as the light is lower. Now, a
powerful search-light can throw a beam upward which will be
seen thirty or forty miles, under favorable conditions. It is
probable that a powerful ray thrown vertically upward from a
lighthouse would be visible long before the direct rays of the
lighthouse could be seen. A somewhat similar scheme has been
tried on railroads, where a beam from the electric headlight of
a locomotive was thrown upward as a warning to the engineers of
other locomotives.”
