Showing figures given in Table II.

Showing from Pumping returns at Atalanta that a large increase of water was lifted with a small increase of coal burnt.

Fig. 4. Showing for London from 1886-1900 the population supplied, the water delivered, and the annual cost of maintenance and management. Attention is directed to the high amount of water supplied in 1895 due to the exceptional quantity used during a period of severe frost. The pumping expenses for the year do not rise in the same proportion, showing that pumping expenses are not necessarily in proportion to the quantity of water lifted.

Fig. 5. Showing in gallons per head per diem the water consumed in trade, municipal, domestic purposes and waste. Where there is a water carriage sewage system a certain amount of "domestic "must be allocated to "sanitary," leaving only a small proportion of the total consumption under the control of the consumer.
