ford, England, Sept. 4, 1873; more than twenty-four hours later another black rain fell in the same small town.
The black rains of Slains:
According to Rev. James Rust (Scottish Showers):
A black rain at Slains, Jan. 14, 1862—another at Carluke, 140 miles from Slains, May 1, 1862—at Slains, May 20, 1862—Slains, Oct. 28, 1863.
But after two of these showers, vast quantities of a substance described sometimes as "pumice stone," but sometimes as "slag," were washed upon the sea coast near Slains. A chemist's opinion is given that this substance was slag: that it was not a volcanic product: slag from smelting works. We now have, for black rains, a concomitant that is irreconcilable with origin from factory chimneys. Whatever it may have been the quantity of this substance was so enormous that, in Mr. Rust's opinion, to have produced so much of it would have required the united output of all the smelting works in the world. If slag it were, we accept that an artificial product has, in enormous quantities, fallen from the sky. If you don't think that such occurrences are damned by Science, read Scottish Showers and see how impossible it was for the author to have this matter taken up by the scientific world.
The first and second rains corresponded, in time, with ordinary ebullitions of Vesuvius.
The third and fourth, according to Mr. Rust, corresponded with no known volcanic activities upon this earth.
La Science Pour Tous, 11-26:
That, between October, 1863, and January, 1866, four more black rains fell at Slains, Scotland.
The writer of this supplementary account tells us, with a better, or more unscrupulous, orthodoxy than Mr. Rust's, that of the eight black rains, five coincided with eruptions of Vesuvius and three with eruptions of Etna.
The fate of all explanation is to close one door only to have another fly wide open. I should say that my own notions upon this subject will be considered irrational, but at least my gregariousness is satisfied in associating here with the preposterous—or this writer, and those who think in his rut, have to say that they can think of four discharges from one far-distant volcano, passing over a great part of Europe, precipitating nowhere else, discharging precisely over one small northern parish
But also of three other discharges, from another far-distant vol-
