So Barbara Oakes now understands about the patterns. Miss James had some books to show the girls, too. They looked up in the encyclopedia about printing of materials and about the other things they wished to know about patterns. Barbara says to her the most wonderful thing is the way in which the warp threads of the loom can be controlled by the Jacquard pattern cards and other devices. The shed of the warp as it is raised for each filling thread is governed by the devices, and a different set of threads bobs up for each shuttle throw. EXERCISES AND PROBLEMS 1. Mount on strips of cardboard, samples of material made: _a._ By weaving, plain, stripes, diagonal, etc. _b._ By printing, resist, discharge, machine, block, stencil; _c._ By embroidery. 2. Look up in the encyclopedia or other books the subject of cotton printing. 3. Try to find pictures of modern looms and more primitive ones in which pattern is controlled by the harness which raises the warp threads and makes the so-called shed. REVIEW PROBLEMS I. Look over the fashion pages of your magazines at home and find: 1. A young woman suitably dressed for business. 2. A girl dressed for outdoor sports. 3. A girl in a party gown. Tell why you think each is "well dressed." If not, why? II. What textile tests would you suggest when buying a silk dress. Mrs. Stark expects to have one next summer. How will she be able to judge if it will wear? III. Can you make another middy at home. Perhaps you are so expert you can take an order for one. THE ELLEN H. RICHARDS HOUSE [Illustration: _Courtesy of Mr. R. J. Planten._ FIG. 150.--The Ellen H. Richards house.] You will be glad to know that all the townspeople in Pleasant Valley were delighted with the year's work in homemaking in the new schoolhouse. Mr. Roberts, the President of the Pleasant Valley Bank, was so pleased with the results both at school and in the homes of the valley that he gave the house that you see in the picture (Fig. 150), to be used for homemaking work by the girls, and for the boys' clubs as well. The house was named for Mrs. Ellen H. Richards, the great and good woman who lived in Boston, Massachusetts, but whose friends are found all over the world, and who helped to develop the teaching of home economics everywhere.
