For this purpose, a vacuum system is used, making possible a more rapid evaporation with a smaller expenditure of fuel.

The greatly diminished atmospheric pressure in Mars will probably more than balance the loss of sun-heat in producing rapid evaporation.

But if the trees are so scattered as not materially to reduce evaporation from the ground, the effect of transpiration in diminishing the moisture of the soil is readily shown.

diameter automatically replenishes the ascertained mean evaporation of the lake during the year, the well containing 105,360 litres when nearly full, and the lake occupying a circle round the platform of 980 ft. diameter, with a depth of 3-1/2 ft.
