HOME ECONOMICS FOR SOUTHERN SCHOOLS. 19 



LESSON 31. 



Problem. — To prepare oil dusters and equip a cleaning closet 

 There should, if possible, be a cleaning closet accessible to the girls 

 on each floor of the dormitory or of the home. If this is already 

 equipped, the equipment should be carefully gone over and put in 

 order. The girls should be responsible for seeing that it is kept in 

 order. This furnishes a splendid opportunity for the study of equip- 

 ment for cleaning. 



Points to be brought out. — Time is saved in cleaning and the work 

 is better done if good apparatus is provided. A cleaning closet is 

 desirable for then we know where to find our cleaning appliances.

 (1912), No. 23. 



Correlation.— English : Write a description of and estimate the cost 

 of equipping a cleaning closet. List costs of improved cleaning appli- 

 ances — dustless dusters, carpet sweepers, and hand vacuum cleaners. 

 Would the gasoline engine used on milk separator and washing 

 machine run a vacuum cleaner ? How ? (Get catalogues and prices.) 



LESSON 32. 



Problem. — To make vinegar. 



Points to be brought out. — Microorganisms are not always harmful 

 in the household. By controlling them properly we may make them 

 useful. We may use them in the making of vinegar.

Supplementary topic. — English: Beekeeping, a vocation for farm 

 women. (Secure Farmers' Bulletins, catalogues.) 



LESSON 33. 



Problem. — A summary of the uses to which we may put micro- 

 organisms in the home. 



Points to be brought out. — The importance of microorganisms in the 

 ripening of cream and cheese, and in bread making. 



Excursion.— Visit the school dairy or a near-by creamery and see 

 how the milk is ripened with a starter, and, if possible, watch the 

 process of cheese making. 



Correlation. — English: Write an account of the excursion. 



Supplementary topic. — Methods of organizing cooperative cream- 

 eries. What household work might be handled cooperatively? 

 Could washing? (See Journal of Home Economics.) 



LESSON 34. 



Problem. — Make short-process bread, using compressed yeast if 

 available. If there is a bakery in the vicinity the yeast can usually 

 be procured there, which grows very rapidly when the yeast is fresh.
