"Scientific American Supplement, No. 433, April 19, 1884"

In addition to this there would also be
a number of belts of "low" centers, which would complicate the thing
threefold at least. At all these different centers the winds would be
blowing from all points of the compass at the same time. Such winds
would not be apt to bring the "meteoric dust" from Java to the United
States, either in an easterly or westerly direction. But, it is said,
"dust" has been gathered.
How high from the surface of the ground has this _dust_ been
gathered--at what elevation?
There is undoubtedly a little dust in the air most of the time, but I do
not think that it extends very high. Where it would be the highest and
most perceptible would be on the arid plans of Africa and Asia, when
the _simoom_ is passing, or in the track of a tornado. But from the
multiplicity of these storm centers and the varied winds they would
produce even this dust could not travel from Java to America.
Again, all clouds, no matter how high or how low, are affected by the
low centers, as the movement of clouds prove, and travel from the "high"
to the "low," from and to all points of the compass.
