84 AMERICAN WHEAT AND CORN. 



As regards variety, the Dent, as would be expected, averages heavier 

 per hundred kernels than the Flint, and with it also lie the extremes of 

 weight, sixty-four grams per hundred and thirteen. In southern lati- 

 tudes the Dent kernels are much heavier than in the northern, between 

 the Middle States and the Southern there being a difference ot ten 

 grams per hundred. In New England Dent corn is hardly ever raised, 

 but the Flint which is raised nearly equals in weight the Dent of Penn- 

 sylvania. Conversely, Flint is only raised in the North and Northwest, 

 and there excels in weight. 



The heaviest corn comes from Virginia, North Carolina, Kentucky* 

 and Tennessee, and from the last-named State the heaviest single speci- 

 men. The weight per hundred kernels in the larger corn-producing 

 States averages about thirty-two grams (or an ounce), Missouri being 

 somewhat higher forty grams. 



Further study of the table will readily show those interested other 

 peculiarities which it is unnecessary to comment upon at length. 



CONCLUSION. 



In ending this report it is merely necessary to call attention to sources 

 of error in work of the kind just described. The chief one is from analyses 

 of samples which misrepresent the locality or substance for which they 

 ^re taken. It is difficult always to avoid such errors, but it is hoped that 

 no mistakes of this sort have crept into the present bulletin. The 

 methods of analyses were such as have been described in previous re- 

 ports, and all results in doubtful instances have been confirmed by 

 duplicate. 



My assistants have been Mr. Edgar Richards, Mr. A. E. Knorr, Mr. 

 Miles Fuller, and Dr. William Frear, and to them is due the credit for a 

 large portion of the analytical work. The baking experiments have 

 been carefully carried on by Mr. John Dugan, while my personal super- 

 vision has extended in all directions. 



In another bulletin the results of further investigation of the cereals 

 will be reported upon.
