privileged groups of society were stratified above and below it.

Following the diagram of levels was a most informing chart arranged like
a huge multiplication table. It gave after each level the words
"permitted," "forbidden," and "permitted as announced," arranged in
columns for each of the other levels. From this I traced out that as a
chemist I was permitted on all the industrial, workmen's and
intellectual levels, and on the Level of Free Women. I was permitted, as
announced, on the Administrative and Royal Levels; but forbidden on the
levels of military officers and soldiers' barracks, maternity and male

I found that as a chemist I was particularly fortunate for many other
groups were given even less liberty. As for common workmen and soldiers,
they were permitted on no levels except their own.

The most perplexing thing about this system was the apparent segregation
of such large groups of men from women. Family life in Germany was
evidently wonderfully altered and seemingly greatly restricted, a
condition inconsistent with the belief that I had always held--that the

Turning to my atlas index I looked up the population statistics of the
city, and found that by the last census it was near three hundred
million. And except for the few millions in the mines this huge mass of

for this population figure was more than double the usual estimates
