Sounds like normal terra cotta wall blocks to me. Here is more
information if you want:
http://www.oldhouseweb.com/stories/Detailed/14512.shtml

These were quite common building units, replaced by CMU today. I
have encountered several gypsum block walls which were similar,
but cast of white gypsum - not as strong as the terra cotta
blocks.

Anyone out there ever heard of "Kankakee Clay Partition"? They
are clay
building materials that are throughout an old (mid 19th century)
barn
building a group I'm part of is looking to purchase in Peoria,
IL.
There's a town called Kankakee not too far from Peoria but so
far I haven't
had time to do much digging beyond the internet.

The pieces appear to be extruded blocks where stacked one way
you see the
sides and they look solid but stacked the other way you can see
the open
structure. I can find some pictures to share if it would help
anyone out.

Thanks.
