EXPERIMENT STATION BULLETINS. 351 



It is not likel}' that any of the foregoing varieties, even had tli^y 

 been planted in a more favorable location, wonid have jiroved superior, 

 or even equal to the four varieties in the next i)receding table, though 

 the Xortlnvestorn and the North Dakota would have jirobably- ripened 

 as well as Dakota Sunshine. The tests of this and preceding season 

 clearly indicate that until varieties have become acclimated or bred 

 under conditions of moisture and temperature which obtain in the 

 Upper Peninsula, the safest varieties to begin with are those which 

 have originated or have been acclimated in North Dakota. Early Adams 

 is the next safest variety, and this no doubt because the variety has 

 become qilite cosmopolitan, being used in many states as an inferior 

 sort of table corn. Gehu as a flint and Golden Dent as a dent variety 

 may well be considered the most reliable for the beginner who there- 

 after has it in his own hands to hasten the process of acclimation by 

 constant selection in which the question of earliness must be rigidly 

 applied. A'arieties Avliich have already ripened in the Upper Peninsula 

 Avould, of course, be much better, and four of these have been found 

 after diligent inquiries and personal investigations during the past five 

 years. Unfortunately there is little if any seed available, for they have 

 been grown merely in small patches, and although they have ripened 

 continuously regardless of seasons, the owners still raise them as a 

 matter of curiosity rather than of economy. All of these four are 

 flint varieties, either white or straw color, and during a personal visit 

 one or two ears from each have been secured, namely from Martin 

 Heim who states tjiat he has ripened the variety during the past 13 

 years in Alger county, J. R. Ryan, who has ripened one in ChippeAva 

 county during the past 17 j^ears, stating that he obtained the original 

 seed from Wm. Greenough, one of the oldest settlers, who secured it 

 from the Indians in the northern part of the county, where it had 

 ripened previously for 80 years or more. The third variety was secured 

 from Ira Carley, who has ripened it in Menominee county during the 

 past nine years, while the fourth was obtained from John Barron, who 

 has ripened it in Delta county during the past 21 years. The difl'erence 

 in moisture, if not in temperature conditions, suggests that the future 

 type of Upper Peninsula corn Avill diff'er from the North Dakota type, 

 and with the material now on hand, it is hoped that valuable results 

 may be obtained from breeding experiments Avhich will be started during 

 the next season. 



In addition to the varieties described. Extra Early Adams was tested 

 during the past season, 20 hills 4 fe*et apart being planted May 25 and 

 giving a yield of 111/, pounds of well-ripened ears, or at the rate of 

 22.36 bushels per acre. 



As a variety better adapted to localities with extensive clearings, 

 such as are found in Delta and Menominee counties, and especially for 

 the purpose of siloing, Dakota Sunshine, recently originated in North 

 Dakota, may be highly recommended. The stalks average 8 feet high 

 or better, generally carry two very large ears T^/o inches long with 

 12-18 rows of kernels and broad leaves of more than average length. 



One row of 20 liills 4 feet apart of Mercer, a yellow flint heretofore 

 tested, was planted May 2G. The row was upon a plot Avhich had a 

 small amount of strawy manure ploAved under for the purpose of observ- 

 ing the effect o|; soil temperature upon field beans. The ears were har-
