232 The Nature-Study Idea 



lections of root-crops and vegetables might 

 be made, not with the idea of keeping them 

 in the school for a long time, but as one of 

 the best means of teaching children to become 

 familiar with the common things of their 

 farms. 



(/) Flowers and weeds. These can be 

 pressed and used as the basis for the school 

 collection. Begin with the most common 

 plants and enlarge the collection slowly. 



(k) Leaves of trees. Press the leaves 

 of some of the most common trees, adding 

 to the collection slowly enough for the chil- 

 dren to learn as they go. 



(/) Fibers: wools of different kinds, 

 cotton, flax, hemp; ropes, twine (particularly 

 binder twine), bagging, fabrics, etc. 

 10. Teach the Babcock milk test. Some 

 schools have demonstrated the use of this test 

 before grange meetings. Complete milk-test- 

 ing outfits suited for school use are manu- 

 factured at small price. Write to dairy supply 

 house for catalogues, and get information from 

 your college of agriculture.
