ANSWER. 65912 Ounces, wget to 4119 Pounds 4, equal to 
514 Gallons, + Pint, equal to 14 Barrels, 10 Gallons, « Pint. 
NOW to find the Quantity of Moifture evaporated from one Acte, 
in the fame Time, proceed by the fame Rule; viz. 
IF from the Surface of one Rod, 65912 Ounces are evaporated in 
154 Days, what Quantity will be evaporated from the Surface of an 
Acre (vz. 160 Rods) in the fame Time ? 
ANSWER. 10545920 Ounicés, equal to 659120 Pounds, equal 
to 82390 Gallons, equal to 2316 Barrels, 14 Gallons. 
- NOW, as we have made this Calculation, let us proceed a little 
further, and enquire what Depth of Water is evaporated from’ the Sur- 
face of the Earth every Day, whereby fome Proof may be given fot 
the preceding Calculation. 
“ NIC. Crugnius (as Mr. Hales obferves, p. 55.) N° 381. of the 
& F bi epics} Zi Pata at found that 28 Inches Depth evaporated in 
role.-Xeartrom Water, 4..¢. 73 of an g Jah each Pie at a mean 
a —- “Bae he —— in a Summer ~ ae 
© Inch; fo the Evaporation of -a Surface of Water isto he Evaporation 
“ of a Sickie of Earth in Summer, as ten is to three.” 
FOR fince that = of an Inch is evaporated daily (ee Water; ‘bie: 
- fore, in twelve. an there will be one entire Inch in Depth evaporated ; 
and confequently in 144 Days, (which as much about: the Length of a 
Summer) one entire Foot in Depth, -provided that Rains were “not, or 
do not fall in that-Time, From this we may eafily account for the 
Wate of Wotan in mage ee Canals, Qe: 
“BUT fince eae the Earth doth; evaporate but 75 of an ae ina Biny, 
therefore one entire Inch in Depth cannot be evaporated under 40 Days. 
“/AND as the firft Cubical Foot of Earth, in the preceding Experi- 
ment, had wafted 194 Cubick Inches of Water, which render’d the 
F | Earth
