Remarks on Results of Gaugings. The whole of the gaugings taken from the 12th of June 1870 to the 15th of July 1871 (a period of 399 days) have been calculated and tabulated, with the following results :

Town Sewage.The sewage received on the farm from the town of Romford during the above period has been

85,999,445 gallons =383,926 tons, and the number of days on which it has been delivered is 373, giving an average quantity of

230,562 gallons=1029 tons per day. This quantity does not, however, represent the total discharge from the town of Romford, because, from the middle of November 1870 to the middle of April 1871, the day-sewage only was delivered on to the farm, the nightsewage being allowed to run on to the meadows at Wybridge between the farm and the town; and for sixteen days in February and March the whole of the sewage was so disposed of, and there are no means of estimating the quantity during this period.

Respective flow of Day- and Night-sewage.--Since the 15th of April last, the new tanks being completed, and the sewage, with a few exceptions, being received continuously on the farm, it has been possible to calculate the respective flow of sewage during the working hours of the day and during the remaining period, and the following are the figures :

gallons.
Day-sewage (average time 10 hours).... 139,153 6211
Night-sewage (average time 14 hours) .. 143,645

tons.

Total... 282,798 1262 The day-sewage is calculated on the basis of gaugings in the sewer during the working hours of the day; the night-sewage is obtained by calculating the difference of quantities in the tanks between the times of stopping the pump one day and starting the next, allowing for the effluent water entering the tanks in the meantime.

By equalizing the time of day- and night-sewage (12 hours each) and computing the quantities on the basis of the above figures, the following is the result:

gallons.

tons. Day-sewage, 12 hours 163,329

729 Night-sewage, 12 hours 119,469 5331

282,798 1262 According to these latter figures the night-sewage would be to the day as 79 to 100, or the day to the night as 137 to 100.

It should be borne in mind that the night-sewage of Romford fluctuates very much, owing to the Brewery frequently sending down a large quantity of water after working hours; this is especially the case on Saturday nights, as a reference to the detailed records will show.

Diluted Sewage pumped.-- The diluted sewage pumped includes, as was explained in the last Report, a certain amount of efluent water, which flows into the tanks, and is there mixed with the sewage as it comes from the town. The engine has worked 366 days during the above period; the average time
