If plants were not in this manner f up- 

 plied with moifturc, it were impoffible for 

 them to fubfift, under the fcorching heats, 

 within the tropicks, where they have no 

 rain for many months together : For thip 

 the dews are much greater there, than in 

 thefe more Northern climates 5 yet doubtlefs 

 where the heat fo much exceeds ours, the 

 whole quantity evaporated in a day there, 

 does as far exceed the quantity that falls 

 by night in dew, as the quantity evaporat- 

 ed here in a fummer's day, is found to ex- 

 ceed the quantity of dew which falls in the 



But the dew, which falls in a hot 

 fummer feafon, cannot poflibly be of any 

 benefit to the roots of trees; becaufe it is 

 remanded back from the earth, by the fol-

 ty of moifturc can have foaked to any con- 

 siderable depth. The great benefit there-
