wrecks on this coast. For the most part these gales appear to be 
partially spent cyclones, which come in from north-east or east, 
and travel down the coast until they begin to recurve to the 
eastward, 
The warning of their coming is usually very short; it consists 
_ of a sudden increase in the sea on some northern part of the coast 
with wind from east to south, and falling barometers, while the 
high pressure over Victoria and South Australia becomes inten- 
sified and progresses into the Tasman Sea. The south-east circula- 
tion about this anticyclone increases in force with the increasing 
barometric grade, and also by the wind circulation about the 
cyclone, and the effect of the two causes acting together is to 
produce a most serious gale. Rarely, these storms originate in 
a ee es 8 eee ee

travelling eastward intensifies on the east coast. Heavy rain is.

and rarely if ever extends inland. 
The storm selected to illustrate this type was a very severe one, 
and began on September 23rd, 1892, about 6 p.m. ‘The barometric
