The Seeding of Grain. 



Size of Seeds. 



Another disturbing element in the quantity of seed which 

 should be sown in order to produce a certain thickness of 

 crop, is the size of the grain of each particular variety. The 

 following table clearly illustrates this, the grains referred to 

 being the produce of 1898, the weighing being done by me 

 the following spring.

t This variety is usually under this weight in the districts where it is most largely 

 grown, but in most localities capable of producing good grain it may weigh from 

 40 to 42 lb. per bushel. 



The above table shows that given single bushels of the 

 same weight and percentage of growth, as many plants 

 might be expected from a seeding of 2 \ bushels of American 

 Beauty, similar to that tested above, as from 4^ bushels of 

 Abundance similar to the sample from Paisley. Also a 

 seeding of 3 bushels per acre of the Potato oats grown at 

 Newton in that year might have been expected to give as 

 many plants as 4 \ bushels per acre of Abundance from Paisley. 

 It does not, however, follow, even where the germination 

 is similar, that the plants from large or small seeds will be 

 equal in strength. This difference in the size or plumpness 

 of particular varieties of grain, or of the same variety from 

 different districts, explains a good deal of the variation in the
