important questions of size and form in tlie udder, and 

 Yield Marks, we are compelled, in the absence of evidence 

 to sustain his classification, to admit, and even to state, that 

 his " system " is an illusion, for the reasons already given 

 in detail. 



Moreover, the evident practical value of the Yield Mark 

 could never have been even established by complicated as- 

 sumption like that of Guenon, in which there is no rational 

 explanation of the duration of yield, or the drying of the 

 udder. There is not even a word of explanation in either 

 of the editions of his work before referred to, of the origin 

 of the escutcheon, correctly, Yield Mark, nor in any way 

 of its certain relation to yield ; a very strange omission, 

 which we have endeavored to correct, in the special chap- 

 ter, demonstrating the origin of the Yield Mark, or index, 

 and its certain relation to both the weight and quantity of 

 yield. The assumed or "created system" of Guenon, 

 while not explaining any important fact, really clouded 

 the subject in a fog of mystery, leading many to doubt, 

 instead of convincing them. 



Guenon is like the man who went a fishing and got a 

 good bite; but his line, or hold on the fish, was not strong 

 enough to draw the fish out of the water. So Guenon, 

 while tugging away at it, really never saw the fish ; never 

 knew in fact whether it was a fish or something else ; 

 hence, he never examined it, understandingly; and con- 

 sequently could not, and did not, explain what sort of a 

 fish it was, or whether it was a fish or something else, that 

 his line was too weak to draw out of the water. 



We again give Guenon credit of discovering the coin- 

 cidence between the size of the Yield Mark and the 

 quantity of yield. But while he only mystified the subject 

 of the Yield Mark by his "system" building, thus causing 

 doubt concerning it ; neither doubt on the one hand, nor 

 mystification on the other hand, can further shake or ob-
