NOW feeing that the Sun-Flower imbibed the Moifture with very near 
three times the Velocity that the Sun evaporated it, 2%. as 10 is to 29, 
which is very near as one is to three; when we water the Sun-Flower in 
very dry Seafons, we fhould allow four times the Moifture that is eva- 
porated by the Sun, which before was proved to be near 27 Pints to 
one Red, viz. 108 Pints, which is equal to 13 Gallons + per Diem. 
And the like of all other Vegetables, in Proportion to their different 
Powers of Perfpiration. | 
TF all the beft Kinds of Fruits were planted in Pots, and cover'd 
with Lead, as in the Experiment of the Sun-Flower, we might very 
eafily know theit different Powers of imbibing and perfpiring : But then 
Care muft be taken to proportion the Magnitude of the feveral Plants, 
as near equal as can be, and to make the Weights of the feveral Pots 
and Earth equal ; that by giving cach Plant an equal Quantity of Water, 
we may every Evening fee the Quantities perfpired, by the Difference of 
their Weights. 
TO be very accurate in thefe Experiments, ‘tis neceflary to make 
Experiments on Plants of one, two, three, four, five, Cc. Years 
G that we might difcover with what different Force they im- 
owt 
And when we are thus inform’d of the different Powers of Perfpiration, 
we may, by comparing their Magnitudes with the Magnitudes of other 
Plants, know their Perfpirations alfo. 
AND fince that the Perfpiration of Plants will be found to be as 
different as the Degrees of Heat and Cold ; *twould be well worth our 
~ while to place Thermometers againft our Plants, to know what De- 
grees of Heat caufed fuch and fuch Perfpirations: And if againft thofe 
feveral Degrees were placed the Perfpirations of thofe Plants, we might 
at all times afterwards behold and account for thofe very great and won- 
derful Operations of Nature, which will be a continual Entertainment, 
: as well as a Directory alfo, teaching us when and how we are to relieve 
our curious Plants and Fruits, in hot and dry Seafons. 7
