1909-10.] Current Observations in Loch Garry. 
at 45 feet, and was variable in direction 2 S. 20 W., 1 S. 30 W., 1 S. 10 W., 
1 S. 60 E., 2 N. 70 E. On the 21st, strong currents, again of variable direction, 
were observed from 75 to 100 feet. On the 28th moderate currents were 
observed down to 75 feet. The current was strongest at 60 feet, and 
variable in direction : — 1 S., 1 S. 70 E., 1 E., 2 N. 80 E., 1 N. 80 W. 
The most notable feature about the observations at the end of the loch 
was the great variability of the currents. The direct surface currents were 
fairly uniform, but no very definite return current was observed. Currents 
were strongest in the neighbourhood of the temperature discontinuity, but

they were nearly always very variable in direction. The diagrams on fig. 1 
represent the observations on 19th August, the directions of the currents 
at the various depths being shown by dots on the compass diagrams. 
Practically all the observations were made during a west wind, and so 
were made at the lee end of the loch. On the 19th a strong west wind 
was blowing, but the general trend of the currents for depths between 15 
and 60 feet is easterly, and the variation in direction and the velocity are 
greatest near the discontinuity. Observations on the 19th will be referred 
to later. 
Observations at the Centre of the Loch. 
Series of observations were made at the centre of the loch on fourteen 
days, and some isolated observations were also made. The most notable
