176 AGRICULTURAL EXPERIMENT STATION. [Jan. 



entire vines. The crop was harvested without delay, yet 

 proved a total failure ; the tubers, almost without an excep- 

 tion, were full of scab and soon rotted. 



The experiments regarding the cause of scab on potatoes, 

 which for several years past have been carried on upon this 

 part of our field, have been transferred to Field E; they 

 have been placed, since the beginning of 1889, under the 

 special direction of Prof. J. E. Humphrey. His elaborated 

 report regarding his studies of scab and other plant diseases, 

 which forms a part of this report, cannot fail to engage 

 the attention of all parties interested in the subject. dis-

Minnesota King Corn. — Two samples were sent on by 

 Northrup, Braslan & Goodwin of Minneapolis, Minn. Two 

 rows were planted May 14 ; the plants reached a height of 

 6') inches and matured during the first week of September. 

 They compared well with other medium-sized varieties 

 current in our vicinity ; no special merits were noticed. 

 The general character of the corn may be judged from a 

 short description and photograph which may be found 

 farther on. 



Oats. — Three varieties were planted. The seeds of two 

 varieties — " Hargett's White" (Seizure) and "Improved 

 American " — were sent by the LTnited States Department 

 of Agriculture; the third variety, commonly called "Con- 

 necticut Valley Oats," was secured from a farmer in our 

 vicinity. The latter, one of the most prominent home 

 varieties of oats, was included in our observation for the 

 purpose of comparing the individual merits, if any, of the 

 different varieties on trial, as far as practicable under cor- 

 responding circumstances. The seeds were planted, each 

 fifteen rows, two feet apart. The main difference in the 

 advancing growth consisted in a deep-green color of the 

 Improved American. The latter exceeded the other varieties 

 hy three inches in height at the close of the season. All 

 matured about the same time, and were cut on the same day, 

 July 19. When harvested, July 23, the entire crop of the 

 Hargett's White weighed 800 pounds; of the home variety, 

 weighed 350 pounds ; of the Improved American, weighed 

 390 pounds.
