showing the nature of a, given sample of seed it has some drawbacks. 

 In the first place the illustration does not show the striking difference 

 in the sizes of the grains composing the various piles. Again the 

 method of piling is not the most effective way of showing the precise 

 relative amounts of the different grades. However those accustomed to 

 wheat are so used to seeing it in piles that this method has been adopted 

 as one that will appeal to the senses through the ordinary channels. 



A better method is that adopted in Fig. 14, on this page, in which 

 every grain is shown, and in its natural size, as is explained in the small 

 paragraph relating to the illustration.

How to Judge the Tabulated 

 All the grains of the lower grades in any sample will 

 lower its quality as seed wheat, the very lowest grades 

 of course being a greater defect than those immediately 

 higher. In harmony with this criterion the samples in the 

 tables may be classed as good or bad according as a majority 

 of their grains are found in the upper or lower grades. 

 Thus a sample that graded : 



would be classed as medium, while one that graded as 

 follows : 



would be called poor or bad. One grading into the lowest 

 grades, as follows : 



would be called very bad, especially if it contained, as would 

 probably be the case, dirty rubbish and split grains.

Fig. 14. A well-nigh perfect sample of a Purple Straw 

 wheat, Farmer's Friend, graded and photographed 

 natural size. None of the small grains have been 

 removed from this sample. It will be noted what 

 a large proportion of the grainsT>elong to the two 

 highest grades. This is the same 

 sample that produced illustration

it is possible to show the actual size of 

 the grains belonging to the various 

 grades a point not brought out in
