in mechanical analysis, since fine material is very difficult to disperse. Sample contains much phillip- 

 site, also plagioclase feldspar and serpentine (?). 



Sample 28. Coarse sand grades consist largely of broken fragments of pelagic foraminifera, with relatively 

 small proportion of unbroken shells, together with numerous benthonic foraminifera, fairly common man- 

 ganese grains and plant material, rare echinoid spines, sponge spicules and ostracods. Twinned crystals 

 and aggregates of phillipsite are very common in fine sand and silt grades. Finer material is quite floc- 

 culent. , 



Sample 29. Sand grades consist almost entirely of unbroken shells of pelagic foraminifera, some stained 

 yellowish brown; together with rare benthonic foraminifera (the shells of arenaceous species consist of 

 broken pelagic shells), ostracods, calcareous algae, bryozoa, unidentified remains of calcareous organ- 

 isms, and fragments of Crustacea. Silt and clay grades are very small in amount. 



Sample 30. Sand grades consist principally of rounded and angular aggregates of fine material; also com- 

 mon manganese and palagonite grains, some broken shells of pelagic foraminifera, and rare flakes of 

 muscovite and biotite.
