In other words, while a point two
inches, say, from the center is going
around a certain number of inches,
a point on the outer edge is going
around greatly increased number
of inches in exactly the same time.

A non-mathematicaI gentleman was
talking to a couple of Civil Service

In general clerical tests, to be

something .snappy,' if you want TO

But to get back to the monographs.
These instruments have been much

to say something disparaging about

used TO listening to nothing except the
Philadelphia symphony Orchestra.

Do you mean the music. or the way
it is played?
Many people, listening to a good fox
trot tune on phonograph. brand it as
Jazz" when there is nothing "jazzy"
about 1t in the world.
One word in defense of the fox-trot
tune.
II Mozart could come back and hear
a good fox-trot. with Its snappy rhythm
and general spirit OF motion and life. he
would like it.
So would Mendelssohn.
AS for Papa Haydn" he would clap
his great hands. swing with the tune,
and then go put some OF the new ef-
fects into a symphony In some of the
symphonies left to US by this old mod
ernist by the way. are to be found
some keen fox trots. although they
weren't called by that name then.
Surely the man who took native
delight in placing a sudden loud chord
in the middle of soft movement, as
Haydn did in his Surprise symphony"
would not fail to appreciate the tricks
of the modern saSophone.
