in Yeast. — Preservation of Grain. — M'to Institution. 



Add pui'e water from time to time as the liquid evaporates, 

 that the oxide may be constantly covered an inch deep. Af- 

 ter two hours continued trituration, a great part of the liquid 

 being allowed to evaporate, the mixture begins to change from 

 black to brown, and then quickly to red. No more water is 

 to be added, but the trituration should be continued. The 

 mass will acquire the consistence of a jelly, and the red be- 

 come still more briUiant with great rapidity. When it has 

 attained its highest perfection, the cup should instantly be re- 

 moved from the flame, or the red will be quickly turned to a 

 dirty brown colour. • 



YEAST. 



The following methods of making yeast for bread are both 

 easy and expeditious : — Boil one pound of good flour, a quarter 

 of a pound of brown sugar, and a little salt, in two gallons of 

 water for one hour; when milk-warm, bottle it and cork it 

 close : it will be fit for use in twenty-four hours. One pint of 

 this will make 1 8lb. of bread. — To a pound of mashed pota- 

 toes (mealy ones are best) add two ounces of brown sugar, and 

 two spoonfuls of common yeast ; the potatoes first to be pulped 

 through a cullender, and mixed with warm water to a proper 

 consistence. Thus a poimd of potatoes will make a quart of 

 good yeast. Keep it moderately warm while fermenting. — This 

 recipe is in substance from Dr. Hunter, who observes that 

 yeast so made will keep well. No sugar is used by bakers, 

 when adding the pulp of potatoes to their risi7ig. — Yorkshire

PRESERVATION OF GRAIN, &C. FROM MICE. 



The following effectual method to prevent mice from eating 

 the grain in stacks or mows, and cheese and other articles, can- 

 not be made too generally known : — 



Mr. Macdonald, of Scalpa, in the Hebrides, having, some 

 years ago, suffered considerably by mice, put at the bottom, 

 near the centre, and at the top of each stack or mow, as it was 

 raised, three or four stalks of wild mint, with the leaves on, 

 gathered near a bi'ook in a neighbouring field, and never after 

 had any of his grain consumed. He then ti'ied the same ex- 

 periment with his cheese, and other articles kept in store and 

 often injured by mice, and with equal effect, by laying a few 

 leaves, green or dry, on the article to be preserved.
