is given in the bulletin. Sixty-one varieties were sown, 56 on this field 

 and 5 on other land. The results obtained this year are given in tabu- 

 lar form for 55 varieties. Another table contains a conij)ilation of re- 

 sults of tests of GO varieties for ten years, showing the yield of each 

 variety for each year it has been grown at the station, and also the aver- 

 age yield for the period it has been grown here. A third table 

 gives the yearly and average yield of 15 of the most reliable varieties 

 grown at the station for six years. The following are especially com- 

 mended : "The Valley, Nigger, Penquite's Velvet Chaff, and Diehl Med- 

 iterranean among the red bearded wheats ; of the smooth, red wheats, the 

 Eed Fultz, Poole, and Finley ; of white wheats. Silver Chaff (smooth), 

 Eoyal Australian (Claw.son),Martin's Amber, and Democrat." 



In another table are contained the results obtained in 1890 with fif- 

 teen varieties of wheat planted on the river bottom on clover sod and 

 after corn, beets, and oats in rotation, and on second bottom-land which 

 had been in wheat nine years. 



The results, as shovrn by the table, do not iudicate that the land on which the ro- 

 tation was followed has been materially impoverished by the successive cropping; 

 but in the south lield, where continuous cultivation has been followed, the etfect i» 

 much more marked. 



Not ouly the total product of straw, but the number of pounds of straw to each 

 hundred pounds of graiu is much less on the high ground than on the bottom-land. 



The grain from the secoud bottom was iu each case equally as good and in most 

 varieties perceptibly better iu quality than that from the lower ground. 



Synonyms. — [The following statements are by the director of the station. ] Sibley's 

 New Golden aud Tasmanian Red appear to be the old Mediterranean under new 

 names. Reliable, Valley, and Egyptian closely resemble each other in the field, but 

 show slight differences in the graiu. We have not been able to distinguish Red 

 Fultz and German Emperor from Michigan Amber. Poole resembles these closely, 

 but is distinct. Witter was classed with them last year, but is distinct aud inferior. 

 The only point of distinction we have yet found between Hungarian aud Geneva 18 

 the excessive smuttiness of the former. Diehl Mediterranean, Golden Cross, Mis- 

 souri Blue Stem, and Seneca Chief are one and the same variety. Royal Australian 

 is the old Ciiiwson under a new and high sounding name. Finley aud Fultz are not 

 distinguishable, whether iu the field or granary. Silver Chaff, Martin's Amber, and 

 Landreth resemble each other so closely that we can not j'et describe their points of 

 dilference, if they have any. Martin's Aujber may prove to be slightly different after 

 further comparison. Of other varieties we are yet in doubt. It is not always pos- 

 sible to decide positively whether two differently named lots of wheat are identical 

 or otherwise from a single season's observations, especially if the seed has been ob- 

 tained from different localities. 



Large vs. small jylats. — The results on the tenth-acre plats in 1890 are 

 compared with those on ])lats of from h to 1.3 acres for four varieties. 

 In only one case is there any material difference in the rate of yield per 

 acre on the large and small plats, and that was probably due to the 

 lodging of the wJieat. 



Bearded vs. smooth and red vs. ivhite wheats. — A table gives the aver- 

 age yields of bearded aiul smooth and of white and red varieties for 

 each of ten years and for this whole period.
