DISCUSSION OF ANALYTICAL DATA. 



Among domestic samples the largest and finest kernels were found in 

 a sample from Wyoming. One hundred kernels weighed 6.19 grams, 

 or one-fifth of an ounce. The smallest kernels were in a sample from 

 Illinois. The sample containing the most moisture, strange as it may 

 appear, was from E^ansas, and likewise the driest sample. In regard 

 to albuminoids, Nebraska leads with a sample containing 17.15 per cent, 

 and Oregon has the smallest portion in any sample, namely, 8.58 per 

 cent. In respect of moist and dry gluten, the Nebraska sample showed 

 the largest percentages, namely, 39.05 and 14.65, respectively, and Ore- 

 gon furnished a sample showing the smallest percentages, namely, 

 12.33 and 4.70, respectively. 



In the Canadian samples, the one having the largest kernels gave a 

 weight of 5.335 grams, and the one having the smallest, of 3.242 grams 

 per hundred kernels, respectively. In albuminoids the extremes were 

 16.10 and 8.23 per cent, respectively; in moisture, 13.98 and 9.38 per 

 cent, respectively; in moist gluten, 38.94 and 6.38 per cent, respectively, 

 and in dry gluten, 15.24 and 2.29 per cent, respectively. 



Of the other foreign wheats, Australia furnished the sample having 

 the largest kernels, namely, 5.723 grams per hundred. The smallest 

 grains were from the Argentine Republic, namely, 2.920 grams per 

 hundred. 



The sample containing the largest percentage of moisture, namely, 

 12.97, was from Australia, and the one containing the smallest percent- 

 age, namely, 8.52, from the Argentine Republic. 



In albuminoids, a sample from the Argentine Republic takes the lead 

 with a percentage of 14.53, while a sample from Australia shows the 

 smallest amount, namely, 8.58 per cent. 



In moist gluten, a sample from Spain gave the largest amount, 

 namely, 32.57 per cent, and one from Australia the smallest, namely, 

 18.72 per cent. Spain and Australia also afforded the maximum and 

 minimum percentages of dry gluten, namely, 12.33 and 7 per cent, 

 respectively. 



For convenience of comparison, the following table of maxima, 

 minima, and means of the Worlds' Fair samples, compared with the 

 means given by the previous work of the Department and by other 

 authorities is inserted.
