INVESTIGATION OF THE SEVERAL BREEDS OF Datry CATTLE. 
“In some scientific books the opinion was confidently put forth that 
if you increase the quantity of fat in the fodder you increase the rela- 
tive quantity of butter inthe milk. Itisa matter of some consequence 
to know these things. When we have made four or five series of care- 
ful experiments in which we have weighed the milk in all its parts, the 
fat, caseine, the sugar and salts, separately, and have weighed the food 
in all its parts in the same manner, so that we know exactly what went 
into the cow and what came out of her, we areina position to say what 
are the facts. Itis not my opinion or your opinion; is is not a case 
of “I guess so,” or “It can’t be otherwise;” all that has little real 
value unless there be behind it an evident basis of impregnable 
fact.”— Prof. Samuel W. Johnson, Yale College, Conn., 1873. 
The above quotation is from an address given many years ago 
by one to whom agricultural science in America, at least, is more 
greatly indebted than to any other of the hundreds who have ably 
contributed to its advancement; and since the above-quoted 
remarks were made very many investigations, more or less com- 
plete, have been undertaken, looking to the solution by careful 
experiment of the comprehensive question suggested by this emi- 
nent scientist. 
Less specific but of the same tenor were those words of Sir - 
Humphrey Davy who said that “nothing is more needed in 
agriculture than experiments in which all the circumstances are 
minutely and scientifically detailed. This art will advance with 
rapidity in proportion as it becomes exact in its methods.” 
Nothing that I can say could add to the words of these eminent 
authorities, and those engaged in the work of investigation will 
be most successful who follow most closely “oi general and 
specific instructions above recorded.
