288 REPORT OF THE F'ARM SUPERINTENDENT OF THE ~ 
pletre 
The data has been obtained for this table by taking the cost of 
fertilizer at the purchase price, without cartage or cost of appli- 
cation, and calculating hay at ten dollars per ton, a common rate 
in our market. 
«. There are many interesting points and deductions which might 
be drawn from the data here presented, but, without entering into — 
any detailed discussion, it seems best to present here only the 
most salient points which were the end sought for in this 
experiment. 
1. On this farm, with our heavy clay soil, nitrogen in an easily 
soluble form is the predominant element for the grass family. 
2. Together with other elements, phosphoric acid and potash do 
not seem to be needed by this soil, though applications of these 
two elements, separately and combined, add a considerable per- 
centage to the crop, yet not enough to bring a profit for the 
application. 
3. Of the easily soluble but ee nitrogen salts, light applica- 
tions are more profitable than greater, ovat the cheaper and more 
soluble sodium nitrate than the other forms tried. 
4, It is probable that two or three applications, preceding light, 
rain, would prove more profitable than a single application 
especially if it should be followed by heavy rain. 
5. This single season’s trials of cotton-seed meal and wheat 

bran indicate that they can be profitably used as sources of — 
nitrogen for top dressing grass lands. 
6. The effect of spring applications of easily soluble nitrogene- 
ous fertilizers seems to be about exhausted during the season. 
7. The second season’s influence of phosphoric acid and potash 
seems to have been to increase the clover, or leguminous plants 
relatively to Timothy or graminaceous plants. 
RELATIVE YIELDS OF FOUR VARIETIES OF BARLEY. 
A small bag of Black Hulless barley was received from D. H. 
Talbot, Sioux City, with the request that it be sown in a com- 
petitive test. 
At the time there was too little space left for many varieties, so : 
two plats, C 7 and 8, were given to the test, and three other — 
varieties of barleys grown here were compared with that received 
from Mr. Talbot.
