552 MR. PRESTON’S NOTES ON THE NORFOLK FLOOD. 
without intermission for a further 15 hours, the intensity had 
greatly decreased, and only '75 in. fell during that period, of 
which but little, it is said, fell after 4 a.m. The total rain 
gauged by me in the 29 hours between 4 a.m. of the 25th and 
9 a.m. of the 27th was the unprecedented amount of 7'34 ins. 
To show how extensive the storm was, at the foot of this paper 
I give a list of the totals of the various stations of the Norfolk 
Rainfall Organisation (with one or two additions) for the 29 
hours ending 9 a.m. August 27th. It is understood that the 
gauges at Dilham and Acle overflowed, which accounts for the 
totals given at these places being so much less than at other 
stations at no great distance. It will be seen from this list that 
all the localities where over 7 ins. of rain were measured were 
in an area between Hethersett on the west and Moulton (near 
Acle) on the east, Sprowston on the north, and Dunston on the 
south, and that the greatest rain occurred at Brundall (8'09 ins.), 
which is about the centre of this area. 
According to the particulars given by Dr. H. R. Mill in his 
interesting and exhaustive paper read before the Royal 
Meteorological Society on the 20th November, 1912, rain 
began to fall as early as 1 a.m. in the neighbourhood of 
Colchester, and the storm centre travelled at the rate of about 
20 miles an hour. In his computation of the total amount of 
rain which fell over Norfolk generally, Dr. Mill stated that the 
2,044 square miles of the county had a mean rainfall of 5'08 ins., 
corresponding to 150,242,000,000 gallons, or a total weight of 
670,720,000 tons. With regard to the amount of water carried 
by the rivers, he stated that a calculation had been made which 
showed that the River Yare at Yarmouth drained an area of 
about 1,200 square miles, of which the total volume of water 
was 102,752,000,000 gallons, which weighed 458,714,000 tons, 
and it was interesting to notice that the Yare and Wensum 
above their junction carried almost exactly one-third of this 
amount. The Yare below the junction of the Wensum, and 
including the Waveney, also carried one-third, and the Bure 
also carried one-third of the total quantity of rain. The 
interesting fact connected with this was that the area of highest
