Newton's rings effects which are produced where sjjherical pigment 

 granules come in contact with the outer transparent layer. The pig- 

 ment also has the very important function of absorbing light not re- 

 flected to the eye as metallic color. The colors seen without a micro-

Wisconsin Arbor and Bird Day Annual, 1904. Compiled by Maud 

 Barnett. Issued by C. P. Cary, State Superintendent. 



This hundred page magazine is prepared with special reference to 

 the school children, with pictures, sketches of birds and trees, selec-

 stimulate nature study among the children for whom it was intended.

 will respect the rights of these birds to life, liberty and the pursuit of
