8 10 THE POP-ULAR SCIENCE MONTHLY. 



other classes are taught. Children's books and papers are shown 

 in the library. In connection with the rearing of children it is 

 perhaps appropriate to mention a collection of photographs of 

 children whose mothers have gone through college, shown in the 

 British educational exhibit. This in refutation of the assertion 

 that college education unfits young women for motherhood. 



Ornamental needlework occupies much space at the fair, but 

 useful articles made with the needle are few. In the woman's 

 room of the Illinois Building is a large and attractively arranged 

 case of children's clothing, called the Lilliputian bazaar. Here and 

 in the Woman's Building are a number of women's inventions to 

 facilitate needlework. The women of Manitoba, together with 

 their embroidery and fancy work, send a creditable display of 

 plain sewing and knitted articles. A similar exhibit comes from 

 Uruguay, and, strange to say, is placed in the Agricultural Build- 

 ing, in the space assigned to that country. It is evident that sew- 

 ing is being made a subject of school instruction in many parts of 

 the United States and also in other countries. The various edu- 

 cational exhibits contain many samples of sewing and mending 

 done by schoolgirls, and the subject is mentioned in a large num- 

 ber of school programmes. Samples of simple millinery, as well 

 as of sewing, appear in the exhibit of the Workingmen's School, 

 of New York. Plain needlework may be seen in the educational 

 exhibit of Japan ; also in that of the Board Schools of London. 

 The exhibit of the Lette-Verein, already mentioned, includes plain 

 and ornamental needlework, dressmaking, and millinery. 



A few exhibits of a miscellaneous character remain to be men- 

 tioned. Three concerns show reversible window sashes, which 

 may be turned into the room, permitting the outside of the glass 

 to be cleaned without discomfort or danger. Among the women's 

 inventions is a wooden roller, covered with some rough material 

 like Turkish toweling, and designed to take up dust from carpets 

 or hard-wood floors. It may be attached to a carpet-sweeper or 

 trundled by a handle independently. With one of the exhibits of 

 domestic hardware in the Manufactures Building is a water 

 motor for driving sewing machines, fans, ice-cream freezers, etc., 

 in any house that has a water supply. Small electric motors 

 adapted to the same purposes are shown in the Electricity Build- 

 ing. These can be used wherever electricity is supplied for light- 

 ing, and some are made to be run by a galvanic battery. The 

 water motor can be set in motion and stopped by turning a faucet, 

 and the electro-motors by turning a switch. An interesting appli- 

 cation of a scientific principle is seen in a cooler for food, beverages, 

 and provisions, which the agent of a Belgian inventor has placed 

 in the Machinery Building. It is in the form of a high dish cover, 

 is made of tin, and covered with a cloth jacket. The jacket is kept
