Character of Bottom 



Smooth mud, purer than pre- 

 ceding two lots, at beginning 

 and mud fairly free from sand, 

 more liquid than much of 

 that taken previously, at end 

 of haul. 



Mud rather liquid, like preced- 

 ing with many much stained 

 shells of Mac.oma and Card- 

 ium, together with shell frag- 

 ments. 



Soft, gray mud, slightly gritty, 

 not very tenacious, at begin- 

 ning and shelly, somewhat 

 muddy sand, at end of haul. 



Very muddy sand. 



Dark, fairly clean, medium 

 sand, with shell fragments, at 

 beginning and sand, with a 

 very little mud and many 

 shell fragments, at end of 

 haul. 



Clean, coarse sand and gravel, 

 stones of all sizes up to width 

 of hand, and 1 inch thick, 

 with many large and small 

 shells and shell fragments, at 

 beginning of haul; sand and 

 fine gravel, but no stones of 

 size taken at end of haul. 



Soft, tenacious mud, slightly 

 sandy, especially in spots, at 

 beginning and mud rather 

 variegated in color and com- 

 position, containing some 

 sand and many shells, at end 

 of haul. 



Sand and fine gravel with some 

 shell fragments; a few living 

 molluscs. 



Fine, uniform dark-grey sand, 

 which washed out very easily, 

 at beginning and tenacious 

 mud, streaked in color, with 

 sandy patches, at end of haul. 



Sand, shells, cinders and un- 

 burned coal. 



Sandy mud with many shell 

 fragments. 



Large stones (about a wash-tub 

 full) ranging to 20 lbs. in 

 weight, several bored by 

 molluscs.
