    Eelation of Area to Flow—continued. At Swadlincote, the sewage from a population of 12,000 drains on to an area of sixty acres, giving 200 persons per acre. The geological formation is Bunter sandstone and di-ift, and we get a good efBuent. [Barwise, 4022.] Would you expect a satisfactory effluent to be produced from a small area of clay land with the high rate, say, of 1,000 population to the acre after chemical treatment and precipitation ?—Certainly not. I do not think that more than iiOO per acre is as much as ever ought to be pat on. [Latham, 4667 ; see 4670.] You do not know what the proportion of population per acre is to the Beddington Farm; 600 acres are under culti- vation?—I suppose there would be about 90,000 people draining into that outfall at the present time. [4676.] (Colonel Harding): You use each acre in turn; you turn the whole of your daily flow on to each acre, such daily flow being 350.000 gallons ?—That is so. [Edson, 5333.] At the end of the twenty-four hours you give that bed eleven days' rest, during which time the sewage passes on right through. [5334.] (Colonel Harding): Then do you think the time is coming when one day in twelve will be too much to give them ?—Yes, I think so. [5357.] You have a table to hand in to the Commission?— I have, it is as foUows :— [Table—Approximate Aeeas.
