a protractor. This may require some time to work 

 out, if the children have never measured angles 

 before, but it is not too difficult if the teacher 

 wishes to undertake it. 

 XII. Magnetizing a piece of soft iron by means of the earth's 

 magnetism (See Gilley, or Miilikan and Gale.) Test 

 poles with a compass and with magnetized needle. 

 Discovery that steam-pipes in the room are magne- 

 tized by the earth's magnetism. 



In handling so large a class, very little individual assistance 

 could be given except in the case of a few who especially needed 

 help. The pupils made their own laboratory manuals, and 

 every laboratory lesson except the first, was discussed before- 

 hand and specific directions for performing the experiments 

 were worked out as a class exercise and copied from the black- 

 board; also suggestive questions to be answered. The recita- 

 tion period following laboratory work was spent in discussion 

 and in writing up the experiments. Simple sketches were made 

 to supplement the brief notes. 



Contrary to our expectations the girls have been as much 

 interested as the boys and have done fully as good work. As 

 the last question of a test, they were asked to state which they 

 had enjoyed more, their study of magnetism or of dairying, — 

 the favorite topic of the fall term. All but two voted for magne- 

 tism, and these were girls. 



In choosing between the various topics, or experiments, 

 most Hked best the dipping needle. As on<e boy expressed it: 'T 

 liked the dipping-needle best, because it took a good deal of 

 patience but when we succeeded in making it we found it 

 something worth while. It had to be almost perfect else the 

 experiment was a failure. Taking it as a whole, I like the topic 

 of magnetism very much. Of course there is quite a bit of it 

 supposed, but one does not care always to study things that 

 have been proven by every body; that is, it's something of 

 which you have a right to express your own opinion or else try 

 to prove what others have tried to prove." 



A girl wrote: 'T have enjoyed most the working out of the 

 fields of force, because it brings out some things invisible and it 

 seems almost magical the way the filings take their positions. 

 It was very interesting to experiment with the magnets in differ-
