<<But that's the point, Doug. Florida grasses are quite different from those

yrs due to changes in grass types and....well...there must be SOME reason
but I'm not sure if the color of such chips might change over time. >>


There is also the effect of strontium 90 on chip color to be calculated and
considered along with the amount of atmospheric nuclear testing being done
during the time period being modeled. The ingestion of strontium 90 by cows was
a serious concern back in the 50's. Walter Cox
