Rural School Leaflet 967 



children would be glad to know about it. We should also like to have 

 photographs of your school showing the improvements that you have 

 made, or of something that you have added to give life and interest, 

 such as window-boxes, a nature-study corner, a terrarium, an exhibit, 

 a tree-planting, or bird-houses. By the way, when you build a bird-house, 

 try to make the roof water-tight, because if the house gets wet inside 

 it does not dry out readily as does the nest in the tree and it is not 

 so pleasant for the birds. Do not fail to read the article by Mr. Allen 

 on page 955. 



Only a word more: I want all the boys and girls who receive these 

 leaflets and who are my friends to become each day more bright and happy 

 and kind and generous. And I want every one of you to honor his or 

 her word, to feel responsibility. One of the finest things in the world is 

 a person who can be absolutely depended on to do a piece of work, do it 

 without watching, and do it well. You want to be such a person. It 

 takes patience and thought and care, but it is well worth while. 



In March I shall send another letter. Meantime, do not hesitate to 

 write to me freely about yourself, and about all the things that interest 

 and occupy you. 



Your friend,

Certified milk is milk that is produced under a legal contract between

 mission is usually appointed by the medical society of a county. Certi- 

 fied milk is milk that is produced under the most cleanly conditions 

 possible. There is a popular belief that certified milk is milk that has 

 gone through a certain process, but this supposition is incorrect. The 

 conditions under which certified milk must be produced vary somewhat 

 with the different commissions having the matter in charge, but the 

 commissions all have regulations that are more or less similar. For 

 example, most of the commissions require that the cows shall be tuber- 

 culin-tested, and that the milk shall be cooled to a certain temperature 

 as soon as it is drawn from the cow. The employees working around 

 the barn and dairy must be in the best physical condition and must
