The Bulletin. 27 



Take some variety of corn, say Cocke's Prolific, that has been bred 

 carefully and intelligently through a number of years for high yield 

 of shelled corn per stalk, and grow it continuously in or adjacent to 

 a field of inferior corn, and in a very short time, especially if proper 

 seed selection is not practiced, it will give much smaller yields, when 

 grown under the same conditions, than the original pure-bred corn ; 

 this being due to the fact that you no longer have pure Cocke's Pro- 

 lific, but a mixture of "scrub" and Cocke's Prolific corn. This fact 

 emphasizes the importance of securing seed from reliable parties. 



EARLY MATURING VARIETIES. 



Iowa Silver Mine, Eiley's Favorite, Learning Yellow, Eeid's Yel- 

 low Dent, Boone County Special and Boone County White are six 

 of the earliest varieties in maturing that have thus far been tested on 

 the farms of the Department. These were all originated in the north- 

 ern-central States, where they have been accustomed to a compara- 

 tively short growing season, which accounts largely for their inherent 

 tendency to early maturity when grown under North Carolina condi-. 

 tions. Earliness, however, we do not consider an important requisite 

 with corn for this climate, except, possibly, where corn is grown in 

 the mountainous section of the State, or where corn, of necessity, has 

 to be planted late, after the maturity of some crop like Irish potatoes 

 or other truck crop. Under these circumstances it may be well to use 

 one of the varieties mentioned above, especially if experience has 

 taught the farmer that local varieties do not thoroughly mature before 

 frost. 



MEDIUM MATURING VARIETIES. 



Biggs' Prolific, Craig's Prolific White, Cocke's Prolific and Craig's 

 Prolific Strawberry mature at a medium date in the fall, and some 

 of these are our most prolific varieties. All these will mature on the 

 different types of soil of the State if planted before July 1. 



LATE MATURING VARIETIES. 



It has been found that Holt's Strawberry, Marlboro Prolific, San- 

 ders' Improved, Weekley's Improved and Mosby's Prolific are the 

 latest maturing varieties tested during the past five years. These 

 varieties generally produce a large and tall stalk when grown under 

 conditions as represented by the Iredell farm, i. e., the results of the 

 past five years' tests at that place indicate as much. 



VARIETIES ADAPTED TO THE EAST SECTION. 



A study of the results of the variety tests conducted at the Edge- 

 combe farm during the past seven years indicates that the varieties 

 of corn best suited to the fine loamy soils of the eastern and south-
