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. 
Reference.—Watson, Rules for Cleaning, Cornell Reading Courses, 1 
(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.
