ss of a mainland, the explanation "up from
one place and down in another" is always good, and is never overworked,
until the instances are massed as they are in this book: but, upon this
occasion, in the relatively small area of Jamaica, there was no
whirlwind findable--however "there in the first place" bobs up.

_Monthly Weather Review_, August, 1898-363:

That the government meteorologist had investigated: had reported that a
tree had been struck by lightning, and that small water-worn pebbles had
been found near the tree: but that similar pebbles could be found all
over Jamaica.

_Monthly Weather Review_, September, 1915-446:

Prof. Fassig gives an account of a fall of hail that occurred in
Maryland, June 22, 1915: hailstones the size of baseballs "not at all
uncommon."

"An interesting, but unconfirmed, account stated that small pebbles were
found at the center of some of the larger hail gathered at Annapolis.
The young man who related the story offered to produce the pebbles, but
has not done so."

A footnote:

"Since writing this, the author states that he has received some of the
pebbles."

When a young man "produces" pebbles, that's as convincing as anything
else I've ever heard of, though no more convincing than, if having told
of ham sandwiches falling from the sky, he should "produce" ham
sandwiches. If this "reluctance" be admitted by us, we correlate it with
a datum reported by a Weather Bureau observer, signifying that, whether
the pebbles had been somewhere aloft a long time or not, some of the
hailstones that fell with them, had been. The datum is that some of
these hailstones were composed of from twenty to twenty-five layers
alternately of clear ice and snow-ice. In orthodox terms I argue that a
fair-sized hailstone falls from the clouds with velocity sufficient to
warm it so that it would not take on even one layer of ice. To put on
twenty layers of ice, I conceive of something that had not fallen at
all, but had rolled somewhere, at a leisurely rate, for a long time.

We now have a commonplace datum that is familiar in two respects:

Little, symmetric objects of metal that fell at Orenburg, Russia,
September, 1824 (_Phil. Mag._, 4-8-463).

A second fall of these objects, at Orenburg, Russia, Jan. 25, 1825
(_Quar. Jour. Roy. Inst._, 1828-1-447).

I now think of the disk of Tarbes, but when first I came upon these data
I was impressed only with recurrence, because the objects of Orenbur
