Among the earnings projection stories for Wednesday, Oct. 17, from The Associated Press:
_ CSX Corp. predicts its shipping volume will be relatively flat in the fourth quarter because demand for coal remains weak and the economy is growing slowly.
_ Fertilizer maker Potash Corp. of Saskatchewan Inc. said its full-year earnings will come in below the low end of its prior forecast mostly because of weaker-than-expected potash sales volumes due to contract delays.
