because, also,
storm-winds are easterly and fair winds westerly, and the former veer from
east around to west, on one or both sides in many cases, there are few
storms which can not be represented as whirlwinds, by a proper _selection_
of _reports_, a corresponding _location_ of the _center_, and an
_extension_ of the lines of supposed gyration, so as to include the
_preceding_ winds, the actual winds of the storm, and the _lateral_, and
_succeeding_ fair weather ones.
But, again, Mr. Redfield is right in saying there is, in such cases, "an
extended stratum of stratus cloud," and it is always present. But why does
he say this _covers the storm_? Is it distinct from it, and if so, what is
it doing there? What power placed it there, and for what purpose? Has this
extended stratum of cloud, which forms the canopy of a vast chamber--five
hundred to one thousand miles in diameter, and less than two miles in
vertical depth, while the earth forms the floor--any agency in producing
the whirl that is supposed to be going on within it, and if so, what? Has
the earth any agency, and if so, what? If neither the ceiling nor floor of
the chamber have any agency in producing it, what does? Are we to consider
the _storm-scud_ as possessing the power, and as waltzing around the
aerial chamber, carrying the air with them in a hurricane-dance of
devastation? _What, in short, is the power, and how is it exerted?_
To these questions, Mr. Redfield's essays furnish no comprehensive answer.
There is an intimation that the cause of storms will be, at some future
day, developed. One attempt, and but one, has thus far been made, and that
I quote entire:
"We have seen that the two Cuba storms, as well as the Mexican
northers, have appeared to come from the contiguous border of the
Pacific Ocean.
"Now, are there any peculiarities in the winds and aerial currents of
those regions, which may serve to induce or support a leftwise
rotation in extensive portions of the lower atmosphere, while moving
on, or near the earth's surface? I apprehend there are such
peculiarities, which have an extensive, constant, and powerful
influence. First, we find on the eastern portion of the Pacific, from
upper California to near the Bay of Panama, an almost constant
prevalence of north-westerly winds at the earth's surface. Next, we
have an equally constant wind from the southern and south-western
