starvation as a primary factor than fatigue which produced the re- 
sult noted. | 
We may infer from this trial that the fat of the body is easier 
carried into the milk than the fat from the food-supply, and this leads 
to the practical conclusion that for butter-cows high condition at the 
time of calving is advantageous, and this idea seems to receive sub- 
stantiation from the general sentiment current with dairymen. 
DuPLICATES. 
In plat work, the first thing to consider is the equivalency of du- 
plicates. It is evident that if a greater difference in yield exists be- 
tween duplicates than occurs between two plats differently treated 
that the difference in yield cannot, in logic, be a measure of the 
efficacy of the treatment applied. It is also equally true that if two 
plats differently treated yield alike, this fact cannot be considered 
as measuring equivalency when two duplicate plats afford great 
variation in yield. If this be correct reasoning, it seems essential 
that we shall have some method whereby we can be assured of the 
equality of the land as respects its evenness of fertility, and for this 
purpose the first thought that suggests is that the amount of the 
preceding crop may serve as a guide. Jor the purposes of testing 
_ the question, certain plats of a likeness in preceding crop were taken 
for a study, and.planted with the same variety of potato, the cut- 
ting of the seed, distances of planting, time of planting, and treat-_ 
ment during growth carefully planned to be alike.
