g 2 ILLINOIS STATE DAIRYMEN'S ASSOCIATION. 



getting ready to teach balanced rations in our public schools, probably 

 not just as he outlined them, but in a rational way, and the Teachers' 

 Association of Illinois has been preparing the way for teaching that very 

 thing. It provides' that besides the regular recitations in Physiology, 

 Botany and Zoology, special recitations for the whole school shall be 

 given each week in observation work from these and kindred agricul- 

 tural and horticultural subjects, in which are taught composition and 

 food value of plants for animal and human use, and composition and value 

 of animal products for food. This year Prof. Davenport, dean of agricul- 

 ture, of the University of Illinois, is furnishing lessons on animal hus- 

 bandry, which assures us that the proper matter will) be taught. Very 

 few county superintendents or teachers now neglect thisi work. It has 

 advanced more than any other improvement in the whole public school 

 system, and well it should, for does not our future existence on the earth 

 depend on our ability to produce our food. Dairy products and high- 

 class lean meat (steak) are the choicest food of the highest types of civ- 

 ilization. The dairymen of Illinois should be very much interested in 

 the management of her public schools, from teacher to State Superinten- 

 dent. As much depends on the sympathy that those in charge have for 

 agriculture and the dairymen's interests. 



I shall call your attention now to some of the matter now being 

 taught in our public schools as relates to balanced rations for milk and 

 meat production. The chart here was prepared by one of our school 

 teachers. It is not perfect in all details, but will help us to understand 

 the use of physiology to the dairymen. 



At the top of the chart we have the outward form of the $2,700.00 

 Jersey cow of the T. S. Cooper sale last May. Opposite is) the same out- 

 line showing the circulation of the blood through the entire system. 

 The upper lines from the *ieart represent the arteries earring the blood 

 out; the lower ones, the veins returning it again to the heart. You no- 

 tice that these arteries are small to the head, limbs, loins, etc., but 

 much enlarged to the udder to carry supplies for the numerous glands 

 in the udder that change it into milk.
