ado, 34.1 bus.; Blue Democrat, 34 bus.; Preston, 33.5 bus.; White 

 Russian, 33.3 bus.; Wellman's Fife, 33.1 bus.; Red Fern, 33.1 bus.; 

 Herison Bearded, 32.2 bus. ; and Seven Headed, 30.1 bushels. Of the 

 newer varieties which have been under experiment for only three years, 

 the following- are among- the heaviest yielders : Kolben, 28.9 bushels, 

 and Climax, 25.4 bushels 



Varieties of Spring Wheat Suitable for the Production of 

 Macaroni. Those varieties of spring- wheat suitable for the produc- 

 tion of macaroni mostly belong- to type No. 3, viz., the hard or flinty 

 wheat (T. durum). Some seven varieties in all have been g-rown at 

 the Colleg-e for several years in succession. The averag-e results of 

 six years' experiments with six of these varieties are as follows : 



It will be seen from the averag-e results of the macaroni wheats for 

 six years, that the Wild Goose variety has given the largest yield of 

 grain per acre, and also the heaviest weight of grain per measured 

 bushel. In the average results for 1904, the greatest yields were pro- 

 duced by the Wild Goose and the Medeah, and the lowest by the On- 

 tario variety. 



Another wheat which has been grown more or less in Egypt, Al- 

 giers, Spain, Italy, and Eastern Europe, and to a very limited extent 

 in America, and which has been used to a greater or less extent for 

 the manufacture of macaroni, is the representative of the species Triti- 

 cum polo7iicutn, and is known under such names as Polish Wheat, 

 Corn Wheat, Colorado Giant Rye, etc. Many extravagant claims have 

 been made for this grain in the Western States within the last two 

 years. The straw of this variety is of medium length and is almost 

 solid. The heads are large, and the outer chaff projects beyond the 

 inner chaff in a peculiar manner. The grains are very hard and are 

 about one and a half times as large as those of the Wild Goose spring 

 wheat. We first grew the Polish wheat at the College in i88g. Care- 

 ful tests of its comparative results, along with other varieties, have 

 been made for at least ten years. In the average of the ten years' 

 experiments, we find that the yield per acre of the Polish wheat is 22.1 

 bushels, and that of the Wild Goose 36.3 bushels per acre. The Wild 

 Goose variety, therefore, gave an average yield of about 60 per cent, 

 more than that of the Polish wheat.
