to the yearly normal or its continuation. It will be seen 

 that the yearly wind resultants which coincide with the 

 direction of the normal, have no disturbing influence; every- 

 thing remains normal, and the extent of the disturbance 

 occasioned by others is proportionate to their deviations 

 one way or the other from the average mean. The result 

 of this comparison is recorded in Table IX., and illustrated 

 in Diagram F (Plate V). The mean line of the diagram is 

 the normal or average for all the years, and the deviations 

 west and east are shown respectively above and below.

Prom a meteorological point of view it would seem of 

 interest that the first half of the curve, up to 1895, is nearly 

 all beloiv the average, while the remainder is nearly all 

 above. This means that during the former period, the 

 winds had a greater tendency off the shore than latterly. 



The second period coincides with the great Australian 

 droughts (1895-1903 and 1904), and it is evident that for 

 the sanie reasons as the winds blow on to the coast in the 

 summer and away from it during the winter, so does also 

 in dry (hot) years, the whole atmospheric drift have an 

 exaggerated westerly (inland) tendency. This as will be 

 seen afterwards, has a direct bearing upon the fisheries.
