PLATE V. 



(Page 48.) 



This is a veiy instructive picture to every young farmer, and there 

 are a good many old ones who may make of it a valuable study. 

 Many persons are not aware that the age of a suckling calf, week by 

 week, can be told by examining the teeth. Look at these drawings 

 and see how easy it is to learn the art — an art which every farmer's 

 boy should understand. So the age of a cow, as well as a horse, 

 can be told from year to year, by looking at tlie teeth, more cer- 

 tainly than by the horns. For this purpose this plate possesses 

 great value ; but it has a greater one in the illustration of what is 

 now well known as the "milk mirror," which is described at ^ 54, 

 and much more fully in Guenon's work, from which the theory is 

 derived. Li this plate the mirror is represented by coloring the pic- 

 ture so as to show the field of upturned hair around the udder in its 

 most fully developed form upon No. 1, and quite defective in No. 4. 

 By studying these, and comparing them with living cows, something 

 of the theory may be learned. It is very fully illustrated in Flint's 

 work ui)Ou milch cows and dairy farming. It is a subject worthy 

 of the attention of all farmers.
