Freezing concentrates sugar (maple sugar), alcohol, and salt solutions as efficiently as heating distils water or alcohol from solutions. Open pans of maple sugar can have the surface ice removed regularly (each day) until a sugar concentrate remains. Salts in water, and alcohol in ferment liquors can be concentrated in the same way.

Wilderness is not a luxury but a necessity of the human spirit, and as vital to our lives as water and good bread. A civilization which destroys what little remains of the wild, the spare, the original, is cutting itself off from its origins and betraying the principle of civilization itself.
Edward Abbey
With their tinted windows up, the cars of the rich go like dark eggs down the roads of Delhi. Every now and then an egg will crack open-a woman's hand, dazzling with gold bangles, stretches out an open window, flings an empty mineral water bottle onto the road-and then the window goes up, and the egg is resealed.
Aravind Adiga
In a battle, as in a siege, the art consists in concentrating very heavy fire on a particular point. The line of battle once established, the one who has the ability to concentrate an unlooked for mass of artillery suddenly and unexpectedly on one of these points is sure to carry the day.
Napoleon Bonaparte
All these soft kinds [of stone] have the advantage that they can be easily worked as soon as they have been taken from the quarries. Under cover, they play their part well; but in open and exposed situations the frost and rime make them crumble, and they go to pieces. On the seacoast, too, the salt eats away and dissolves them, nor can they stand great heat either.
Vitruvius
The last best hope of earth, two trillion dollars in debt, is spinning out of control, and all we can do is stare at a flickering cathode-ray tube as Ollie ''answers'' questions on TV while the press, resolutely irrelevant as ever, asks politicians if they have committed adultery. From V-J Day 1945 to this has been, my fellow countrymen, a perfect nightmare.
