seqiiently the deposition of moisture under natural circumstances 

 would most likely be confined almost entirely to the few outer 

 layers of a patch of these reeds, thus materially diminishing the 

 average amount of moisture deposited. In all probability the effect 

 of a fog or mist on reservoirs is mainly beneficial as a check 

 on evaporation. 



Again, as both iron and vegetation are good radiators of heat, it 

 follows that under a calm, clear sky a certain amount of dew would 

 be deposited during the night, thus complicating matters still further, 

 unless special observations were made and daily readings taken. 



The nett result of the experiments seems to be that it has been 

 proved that a deposit of water takes place on growing plants during 

 the prevalence of the " South-Easters," probably sufficient for their 

 nourishment during the dry season, although it is possible that the 

 plants would thrive equally well in a humid atmosphere, from which, 

 however, no actual deposition of moisture took place, as on the 

 lower slopes of low hills during the prevalence of a sea breeze. As 

 far as actual quantitative results are concerned, the problem is as far 

 from being solved as before these experiments were undertaken.
