It was, he says, not so extensive as the recent ones, but on that 
occasion the rain fell at Moonagie, near Cannonbar ; the River 
Bogan was dry throughout its course, except a waterhole at long 
intervals. The rain fell over only about a mile and a half of the 
‘river, and for only about one hour, but such a quantity of rain 
fell (we had no rain gauges then) that the river ran for seventy 
miles, into the long waterhole at Gongolgon. The rain was 
accompanied by large hailstones, which went through verandahs, 
and killed emus and kangaroos, and stripped all the leaves off 
the trees till they looked like English trees in winter.” 
GOOD SEASONS. 
Looking at the diagram, we find that there are as many good 
seasons as bad ones. Some of these recur with great regularity, 
for instance, the two years immediately before the commencement 
of A drought, and likewise the two years immediately following 
D drought. Then there are three good years together that come 
as arule four years after the centre of A drought; their regularity 
is made uncertain by the irregularity of the end of A drought.

In 1893 we had the lowest grass temperature on record, and 4

runs—on the coast— 
1893, heavy floods, lowest grass temperature on record. 
1874, many heavy floods. 
1855, no record of this year. 
1836, abundance of rain, snow fell in Sydney. 
1817, high floods on the coast and inland.
