86 STORMS ON THE COAST OF NEW SOUTH WALES. 
generally precedes the storm; they seldom last over three days, 
n the majority of cases the dangerous part of the storm does 
not last two days. The velocity of the wind seldom exceeds 40 
miles an hour ; but the down-pour of rain seems to add force 
to the wind, and makes hae air so thick that it is ae leaie to 
blows. The most terribl cks on o ast haye been in these

Erroneous opinions as to the cause of them, and the indiea- 
tions which mark their approach, have frequently been publish 
and I must confess that it is only a recent investigation ‘inti 
records of the Observatory which has made clear to my own 
mind what place we are to assign to our south- east storms. if,

For this purpose, I have taken the anemometer a other self- 
registered results in the atin. and I find that since 1870 
we have the following faets : 
During 1871 the igi te winds were very strong in the 
winter, and twice — — heavy gales om west, running up 
the daily number of miles to upwards of 570, took place, an we 
had no easterly gale. 
In 1872 the winter was marked by still stronger westerly 
winds, which twice in June reached over 500, and in July reached 
592 and 759 on s eparate days. These figures represent very 
heavy westerly gales, and we had no easterly gal 
In 1873 we find a very marked falling off in an force of the 
westerly wands; and in June, from Ast a o 19th, we had an

this year, another moderate S.E. gale broke on the co
