(the limit of accuracy of the current meter). On 2nd August and on the 
morning of the 3rd it was calm, and currents were very slight, indicating, 
either that currents produced by the storm of the previous day had died 
away very rapidly, or that the storm had not continued long enough to 
produce steady currents. Probably the former is the correct explanation. 
A moderate but steady wind blew on the afternoon of the 5th and on the 
6th. Currents in the same direction as the wind were recorded down to 
depths of 25 feet. At 45 feet there was a fairly strong current, but 
unfortunately no direction was recorded by the meter. We may assume,

however, with some certainty that it was?a return current. On the 7th 
there was again a very strong current at 50 feet, with very variable 
direction, and also on the 9th. On 10th August there was a calm, and only 
very slight currents were recorded. On the 14th and 16th, though the 
wind was steady the currents were slight. On the 18th and 19th there 
were strong westerly winds, and on the 19th strong currents were recorded 
at all depths. Below 30 feet, i.e. below the direct surface current, the 
directions were very variable. The velocity of the current was strongest 
at 45 feet — 6 centimetres per second — and the following were the recorded 
directions 2 S. 10 E., 1 S. 70 E., 1 N. 50 E., 1 N. 60 E., 1 N. 30 W * Strong 
winds continued on the 20th, and again the current was of greatest strength
