the final line of stitching will come on the right side. Instead of a 
band a flat, fitted binding or yoke about 2 inches wide may be used 
around the top. 
References.—Same as in Lesson 90. . 
Correlation.—English: Write description of the different kinds of 
plackets and their uses. Compare cost of home-made and ready- 
made underwear. Is woman’s home work worth money ? 
LESSON 99. 
Problem.—Cereals and their value in the diet. 
Points to be brought out.—Cereals contain all the necessary material 
for the formation of the new plant. The outer layers contain the 
largest proportions of mineral matter, and also of plant fiber; the 
inner sections are richest in energy-yielding starch. 
Reference.—U. S. Dept. Agr., Farmers’ Bul. 249. 
Correlation.—English: Look up the countries in which the different 
cereals are grown and list them. Could any new cereal be introduced 
into your community ? 
LESSON 100. 
Problem.—To finish the bottom of the drawers, make buttonholes 
and sew on buttons. 
Points to be brought out.—¥inish the bottom of the drawers in the 
same way as was done with the neck and sleeves of the gown. The 
traditional finish, a ruffle, is not only more work in making and 
difficult to launder, but is objectionable in that it gives an excessive 
amount of fullness at a point where fullness is not desirable. 
References.—Handy and Pract. Farm Libr. [Missouri], Mo. Bul., 13 
(1915), No. 2, pp. 70, 71; clothing text. 
Correlation.—English: Discuss simplicity in dress. How far is 
the elaborateness, which means extra work, justifiable in woman’s 
dress ? 
LESSON 101. 
Problem.—Wash a wool sweater. 
Points to be brought out.—A neutral soap must be used, since an excess 
of alkali injures the fiber. The water used should not be too hot, 
and the successive waters should be of uniform temperature, for rapid 
expansion and contraction of the fibers tend to cause felting and 
shrnking. Too much rubbing also tends to felt or mat the fibers. 
Reference.—Any good book on home laundry work. 
Correlation.—English: Find cost for power-driven washers of 
various types—cost per week. (Consult catalogues for laundry 
equipment. ) 
LESSON 102. 
Problem.—To prepare tapioca, macaroni, and spaghetti. 
Pownts to be brought out.—These are often prepared in an unappe- 
tizng way. We should aim to season them well and not allow them
