374 Mr. barker’s Regifter of the Weather . 
The falt-water, being again fet abroad, froze as before ; 
what remained fiill unfrozen was now become exceeding 
fait, but the ice, drained and diffolved, was little if at all 
brackifh. This agrees with what Captain cook men- 
tions in his late voyage, that in 6 i° 35 ' South latitude 
they filled their water cafks with frefh-water, melted out 
of ice found floating in the lea. By this experiment, if 
another time more fully repeated, it may be found to 
what degree the faltnefs of water may be increafed, by 
continuing to freeze away the frefh-water. 
May not the knowledge of this be of ufe to the fait- 
makers, efpecially in cold countries ? The Sun is flrong 
enough of itfelf between the Tropics to dry away the- 
fea-water into fait; and, I think, at the falt-works near 
Lymington, they increafe the faltnefs of the fea-water 
by drying it away in the Sun before they boil it into fait. 
And this leems to be another means of parting frefh- 
water from the fait, which would fave expence in boil- 
ing it away, and may be of ufe in the cold countries, and 
in winter*
