POMOWN A: Or, 
AND, as it has been proved, that in 21 Days near 26 Ounces were 
evaporated from one Circular Foot, therefore multiply 346 (the Number 
of Circular Feet in one Square Rod) by 26, (the Quantity evaporated 
from the Surface of a Circular Foot in 21 Days) and the Product will 
be 8996, which is very near the Quantity of Ounces that are evaporated 
from the Surface of one Rod in 21 Days. 
IF 8996 be divided by 16, (the Ounces in a Pound Averdupois) 
the Quotient will be 562 4, the Quantity of Pounds Weight evaporated. 
IF we admit, chat one Pound of Water is equal to one Pint, we may 
eafily reduce the 562 2 Pounds into Gallons : For 562 being divided 
by 8, the Number of Pints in a Gallon, the Quotient is 26 44, the 
Quantity of Gallons evaporated from one Square Rod in 21 Days. 
NOW by the Rule of Proportion : 
IF, in 21 Days, 8 996 Ounces be evaporated from one Square Rod, 
what Quantity is evaporated =e the fame Surface in 21 Days ? 
ANSWER. 428 Ounces, equal to 26 Pounds 12 Ounces, equal 
to three Gallons, one Quart, aad chxce Quarterns,

N.B. IF the judicious Gardener does well confider this, he will 
be eafily led into the Reafons of watering Plants in dry Seafons. 
NOW, fecing that we have obtained the daily Evaporation of one 
Rod, I will proceed to a further Enquiry, viz, What Quantity of 
Moifture is evaporated in the Space of a whole Summer ; which I begin at 
the 1 5th of May, and end at the 15th of Ofober, containing 154 Days. 
BLY the Rule of Proportion : | 
_~ TE, from the Surface of one Rod, 428 Ounces are evaporated in one 
Day, what Quantity will be evaporated from the fame Surface in 15.4
