DISCUSSION ; The storage boxes of carded core samples can be kept in work 

 offices, and large numbers of cards can be laid out on a desk or table for 

 study. Continued restudy can be made with a minimum of effort. Also, the 

 cards readily fit under a standard light binocular microscope for detailed 

 examination and estimation of mean grain size or abundance of certain grain 

 types or organisms. Duplicate core cards can be easily sent through the 

 mail to a colleague for collateral study and the cards can be photographed 

 for inclusion in analysis reports.
