 Division, who rendered valuable assistauce. 



The principal results of the three years' experiments are arranged 

 in as condensed a manner as possible in the following table. In every 

 case where the rust could not be graded for more than one season the 

 variety is omitted from the table. Nearly every instance of this kind 

 was in the case of a variety that winterkilled or failed otherwise after 

 the first season, but in wsome cases they were simply not at hand for 

 planting more than the one season. As a result of this disposition only 

 about one-third of the varieties actually planted during the three years 

 are represented in the table; hence it shows no varieties from Greece, 

 England, Holland, India, Siberia, Argentina, or Algeria, although they 

 were obtained Irom each of these countries. In the case of the varieties 

 from Argentina and Algeria they were simply received too late to be 

 tested except in the severe season of 1890-07. 



Only those who have had similar experience can form any idea as to 

 the work required to keep the nomenclature of varieties from being 

 confused. It is not claimed that all the names in the table are right, 

 for such a claim would be preposterous; but it is believed that nearly 

 all are fairly reliable, or at least as correct as they can be in the pres- 

 ent confused condition of our wheat nomenclature. Moreover, many 

 apparent errors are really the correct names, the seeming discrepancy 

 arising from translations of the original name into a different language, 

 or they are cases of pure synonyms; for instance, Kaiser and German 

 Emperor are very probably the same variety, while Kubanka and 

 Beloturka, Black Sea and Arnautka, Thick-set and Cone Kivet, Club 

 wheat and Oregon Club, Genealogic and Hallets Pedigree, Soules, 

 Flint and Yorkshire, German Amber and Amber Winter, De Bordeaux 

 and Eouge Inversible, etc., are all cases of synonyms. The peculiarity 

 of some of the names is doubtless due also to bad orthography, as for 

 example, a certain hybrid is not Tamed but Lamed. In French names 

 incorrect spelling is common and in llussian names it is the rule. 

 Sometimes such simple names as Gold Drop and Blue Stem are applied 

 incorrectly to the most widely different varieties, and such names as 

 Turkey and Russian Red either mean very little or may even be mis- 

 leading, giving no clue to the origin of the varieties as one might sup- 

 pose. A thorough revision of the nomenclature of our varieties of wheat 

 is a most important desideratum for this country. 



The two main obstacles to a successful comparison of the rustiness of 

 a large number of varieties according to the method followed in the 

 experiments, are (1) that the varieties being necessarily planted at dif- 

 ferent dates those equally susceptible to rust may nevertheless not be 

 equally rusted at the time of grading, and (2) it is impossible to care- 

 fully grade the rustiness of more than one hundred varieties a day. 

 However, in case of the experiments here described, both obstacles were 

 overcome to a considerable degree by grading the varieties each season 

 in the order in which they were sown; but notwithstanding this, many
