but if this rain is lying around, in a kind of a general
way on the ground, it is then definitely located,
it is DOING SOMETHING--that is, RESTING (which is one
of the German grammar's ideas of doing something), and
this throws the rain into the Dative case, and makes it
DEM Regen. However, this rain is not resting, but is
doing something ACTIVELY,--it is falling--to interfere
with the bird, likely--and this indicates MOVEMENT,
which has the effect of sliding it into the Accusative case
and changing DEM Regen into DEN Regen." Having completed
the grammatical horoscope of this matter, I answer up
confidently and state in German that the bird is staying
in the blacksmith shop "wegen (on account of) DEN Regen."
Then the teacher lets me softly down with the remark
that whenever the word "wegen" drops into a sentence,
it ALWAYS throws that subject into the GENITIVE case,
regardless of consequences--and therefore this bird stayed in
the blacksmith shop "wegen DES Regens."

N.B.--I was informed, later, by a higher authority,
that there was an "exception" which permits one to say "wegen
DEN Regen" in certain peculiar and complex circumstances,
but that this exception is not extended to anything
BUT rain.

There are ten parts of speech, and they are all troublesome.
An average sentence, in a German newspaper, is a sublime
and impressive curiosity; it occupies a quarter of a column;
it contains all the ten parts of speech--not in regular order,
but mixed; it is built mainly of compound words constructed
