or " crow foot" millet, gave ten and one-half tons per acre. One- 

 fourth acre of each was fed green to cows, with very satisfactory 

 results. It would appear to be fully equal to good corn fodder, 

 and is more closely eaten, there being absolutely no waste. The 

 crop from three-fourths of an acre of each variety was put into a 

 silo, which has not yet been opened. I consider these very 

 promising fodder crops for the purposes for which we have used 

 them, but not for making into hay, as they are too coarse for that 

 purpose. 



Three varieties of soya beans have been under cultivation. 

 These have given yields of from about twenty-two to twenty-eight 

 bushels per acre. It is significant that the yield has been greatest 

 where the tubercles which are connected with the assimilation of 

 atmospheric nitrogen were most abundant. The cause for the 

 wide differences noticed in the number of tubercles upon the roots 

 in different fields will be studied another season. At present we 

 are unable to determine whether these differences were due to 

 variety of b^an, or to location ; though it is believed that the fact 

 that soya beans had previously been grown where the tubercles 

 were this year most abundant is a sufficient explanation of the 

 phenomena noticed, for this would mean a greater number of 

 germs in the soil, as the certain consequence of the previous culti- 

 vation of the crop upon which the tubercle bacilli develop. 



The large white Japanese radish has been under trial as a field 

 crop. This seed is generally sold in this country under the name 

 Chinese radish, as the Chinese as well as the Japanese make 

 extensive use of this root as food. The crop can have no impor- 

 tance here for this purpose, as its flavor is too strong ; but it is of 

 possible value as a crop for cattle or sheep. It grows in about 

 the same length of time as the larger English turnips, and gives a 

 heavy yield. Although our seed was far from the best, we got in 

 different fields from fifteen to twenty-two tons per acre. Sheep 

 and cattle eat it greedily, and its food value is probably about the 

 same as that of English turnips. It will be analyzed for the 

 determination of this point. 



Small areas of hemp and flax of several varieties have been 

 successfully grown, but do not promise to be profitable. White 

 mustard gave us at the rate of twelve and one-half bushels of seed 

 to the acre, the yield being very light, on account of injury from 

 worms at the root while the plants were growing. This crop is 

 under careful experiment as a nitrogen conserver and soil im- 

 prover.
