Koohii stories:

1) [nolusu] 7-8-2007(154): The strata have piled up in an ever increasing pile of dirt. As the geologists go down the rocks, they flag each stratum with the name of the corresponding era.

2) [PacifistGod] 12-4-2007(135): Archaeologists at a dig site place small flags marking layers or strata of rock. Each of these layers was formerly the top layer. (This is not increase! Hseige keeps messing up).

3) [AndamanIslander] 5-5-2008(93): Formerly, in Japan, each social stratum had to wear specific types of clothes to flag their social class and caste. Of course, these days Japanese society isn't so regimented anymore.

4) [stehr] 2-10-2007(42): Everyone being worried about the earth's upper stratum (greenhouse gases and holes in the ozone) has caused an increase in red-flags warning of this.
