and on the severity of the threshing. Thus, as in oats and other grains, the 

 shorter and thicker the kernels -the more closely they may be packed in a 

 given measure and consequently the higher the weight per bushel. Severe 

 threshing produces a shorter, blunter kernel and is often resorted to as a 

 means of increasing the weight per bushel of a mediocre ware. The objections 

 to such a practice are clearly pointed out in that not only is the apparent 

 value of sorts so treated exaggerated, but at the same time there is great 

 danger of injuring the germs of the kernel and thus reducing the germinating 

 power. The weight per bushel of the leading two-rowed sorts at Svalof 

 is given later in connection with the table of yields. 



The time of development is an important consideration in barley culture 

 in Sweden as even in the most southern parts the grower desires as early a 

 sort as possible so long as earliness be not obtained at the sacrifice of yield 

 or other practical qualities.

 trial plots of barley (Aug. 9, 1910). 



Of the large number of two-rowed strains isolated and tested during 

 the nineties, the following are the most important: 



Princess out of the old English Prentice; Chevalier II out of American 

 Chevalier; Gute out of a native barley peculiar to the Island of Gotland; 

 Primus and Swan-Neck selected from a mixed stock said to have been the 

 product of a crossing between Imperial and a common two-rowed sort; 

 Hannchen out of the Austrian sort known as Hanna.
