first made, that one ton of burnt lime or two tons of ground 
limestone to the acre be applied once in six or eight years, 
is apparently ample under average conditions. At the Jack- 
son Station the effect of lime on soy beans and cowpeas was 
unusual, the crops being practically doubled. Soil and fer- 
tilizer problems continue to be of first importance, both on 
account of the demand of the agricultural interests of the 
State and the large numker and wide divergence in plant food 
requirements of the soil types.'’ 
Dairying. 
The following from the report of the dairyman should be 
interesting in view of the fact that a model dairy is projected 
by the College of Hawaii, from which as good results for the 
dairy industry here as those that the University of Ten- 
nessee is offering the dairymen of that State may be expected : 
‘‘Feeding experiments wdth the dairy herd were conducted 
throughout the months of January, February, and IMarch. 
Home-grown feed stuffs were compared with commercial feed 
stuffs with reference to efficiency and economy of production ; 
also different home-grown rations were compared one with 
another ; while special attention was given to increased pala- 
tability of the rations during these three months of experi- 
mental feeding. The work as a whole should be repeated be- 
fore the results appear in bulletin form. A few conclusions, 
however, stand out preeminently. They are as follows : 
‘T. Home-grown rations are just as efficient as commer- 
cial rations, and more economical. The secret of successful 
dairying in Tennessee is to reduce the cost of production by 
feeding these home-grown rations. 
“2. Soy-bean meal is equal to cotton-seed meal for milk 
production and is cheaper, Avhile the bean stover is more 
relished by stock than corn stover. 
“3. Palatability will imnrove the efficiency of any rough- 
age ration by increasing the digestibility of the components 
of the ration and stimulating the appetite for greater con- 
sumption. This desired feature in feeding was secured by 
mixing the cut stover, hay, and straw with corn and sorghum 
silage in alternate layers and sprinkling each layer of the dry 
roughage with salt and water and allowing the wdiole to 
stand twelve hours before feeding. 
“The herd of 30 cows for 1909 shows considerable improve- 
ment over 1908 in milk and butter-fat production and profits. 
The average cost of keening each cow Avas $5.66 greater than 
for 1908. This was due to the fact that they Avere rather 
more liberally fed on grain, and consumed more roughage 
as a result of palatable rations. The aA^erage increased pro- 
duction for each coav over 1908 Avas 375.2 pounds* of milk and 
23.14 pounds of butter-fat, equivalent to 26.99 pounds of but-
