35. Consistency tests were devised to compare collected quantities of 

 sand from traps placed in close proximity. Since the traps had not yet 

 undergone testing in the laboratory, it was necessary to obtain some indica- 

 tion of the reliability and reproducibility of results. In the consistency 

 tests, two traps were placed in the surf zone approximately 1 m apart. The 

 seaward trap was located a distance sufficiently downdrift of the shoreward
