A NEW TYPE OF RED CLOVER. 



cloudburst, more than 5 inches of rain faUing. The neighboring 

 creek overflowed its banks, inundating the whole bottom and sub- 

 merging the jlover plats with from 6 inches to several feet of water. 



This misfortune threatened to make impossible the securing of 

 further data concerning the varieties. However, the excellent drain- 

 age of the field saved it from serious injury, and at the end of a week 

 it was possible to proceed with the harvest. 



The following table shows the yield of cured hay produced by 

 each of the strains used in the experiment at this place:

COMPARISON OF YIELDS. 



The low yields of the samples of clover from western Ohio and 

 northern Indiana are due to the injury they received from the 

 flooding previously mentioned. A ''run," or former creek bed, 

 which extended diagonalh^ across these two plats was transformed 

 into a torrent and did considerable damage to both of them. With 

 these exceptions the injur}^ by water was equal on all plats. The 

 comparatively low jneld of the New^ York and Pennsylvania strains 

 may be explained, in part at least, by the fact that the west side 

 of the field, along which these were sown, had not been under culti- 

 vation as long as the remainder of the field and hence was not so 

 well subdued. 



The total yield of cured hay from the 22 acre plats was 87,982 

 pounds, an average of 3,998 pounds, or nearly 2 tons, to the acre. 

 Leaving out of consideration the plats that suffered from apparent 

 external injuries, the plat sowm with Wisconsin seed gave the lowest 

 yield of the domestic varieties, while that sown with seed from 

 eastern Ohio gave the highest yield. The yield of the former was 

 2,970 pounds, something more than 1,000 pounds below the average 

 for all plats, while that of the latter, 4,640 pounds, was about 650 

 pounds greater than the average. 



As was the case in the experiments at Oakland, Nebr., the hairless 

 Orel clover No. 16 gave not only the heaviest yield among the
