additional net profit of $9.08. Comparing the data in the case of 

 plots 17 and 21, it will be seen that an expenditure of $9.32 for 

 nitrate of soda resulted in an additional net profit of $25.30 per 

 acre. In order to show more clearly the increase in the profits from 

 the use of liberal amounts of nitrate of soda, the value of the 

 crop over that of the manures is given for the plot without nitrate 

 of soda, for that with a one-third ration, and for that with a full 

 ration of the nitrate. These data show the results secured for the 

 entire period of four years already covered by the experiment, as 

 follows :

Pasturing Timothy. Timothy is not well adapted to 

 being pastured. Animals grazing it close soon destroy it. 

 The bulbs must have chance to develop and store them- 

 selves with nutriment for the following year, and pastur- 

 ing would not allow this. It is injurious to a timothy 

 meadow to pasture it after the hay has been cut. The 

 one exception to this rule is, should there be danger of 

 so much aftermath lying on the ground that it will en- 

 danger smothering or harbor too large a number of field 

 mice, it may be well to pasture lightly in the fall. There 

 is a time in late spring when the weed commonly called 



*Potash and phosphoric acid. fPotash. phosphoric acid, and 

 nitrogen.
