tion in South Missouri is the Gartner variety. For the past sea- 

 son it will be noted that it was tenth in yield while averaging the 

 last three years it stands fourth in order of yield in South Mis- 

 souri. 



In comparing the tests for the years 1906, 1907 and 1908 with 

 the past season we can not but be impressed with the fact that 

 each variety is particularly adapted to a certain set of conditions 

 and the variety which does best one season may not do as well as 

 some other variety with other seasonal conditions another year. 

 The Reid's Yellow Dent the past season compared with the aver- 

 age of three years, also the Gartner brings this point out very 

 strongly. After this has been said, however, one should again 

 consider the fact that taking the yield of all of the different years 

 together there are two or three varieties which have been shown 

 to be very high yielding ones under all conditions whether in North 

 Missouri or South Missouri or with varying seasonal conditions. 

 These varieties would, of course, be the Gommercial White, Boone 

 Gounty White and St. Gharles White. Most of the other varieties 

 seem to be influenced more or less largely by seasonal conditions, 

 climatic and soil differences.
