BIGELOW: COAST WATER EXPLORATION OF 1913.: 229 
ranging from .14 knot to .5 knot, greatest when the flow was south- 
westerly and northwesterly. The total drift was about 1 knot to- 
ward the northwest. These three sets were planned to cover the last 
half of the ebb, and the first half of the flood. But the observations 
show that the flood current had begun to run one to two hours earlier 
than the time of low tide at Barnegat. Hence, the set must have been 
confined to the flood, and therefore can not show whether there was 
any dominant drift. To remedy this defect it would have been 
necessary to continue the set for six hours more, but this was impracti- 
cable, owing to a sudden squall. Consequently a third set of current 
measurements was made the next day at Station 10074, so timed as to

jluring the last of the flood. It then veered gradually through north- 
\vest, north, and northeast to east, in which direction it was running 
with a velocity of .3 knot at the end of the set. The velocities were .6 
mot for the first two hours; .1 knot to .4 knot after that. The total 
\et drift was about 1.5 knot to the northwest. 
| The bottom readings were less satisfactory than those on the surface, 
ecause of the weakness of the current. In general the flow was
