E. T. Quayle: 



Gulf is about 19 miles wide, though, owing to coastal irregu- 

 larities, the two places are about 28 miles apart. Point Lowly 

 and Point Germein are 12 or 13 miles apart on opposite sides 

 of the base of a narrow triangular water area, the apex of which 

 is 45 miles further north. Owing to the way Pt. Lowly pro- 

 jects into'the Gulf, it is only about 30 miles from Pt. Pirie, in a 

 north-westerly direction. All four stations are practically at 

 sea level. ' The wind directions were determined from the 9 a.m. 

 weather charts, and it was, therefore, necessary to deal with the 

 total wind change in 24 hours, which, of course, varied consid- 

 erably. These total variations were grouped as follows : Winds 

 veering (a) from north through west to south by west, (b) 

 from north through west to west-south-west, (c) from between 

 west-south-west and south by west, (d) winds with an easterly 

 component (e) indeterminate, as in purely cyclonic circulations. 

 Seven years' daily records were used, and the results for each 

 year (1911-1917) are shown in the following table: —
