EXPERIMENT STATION RECORD. 



The wheat was wet and at the close of the sproiitiug period was dried 

 until it had the same water coutent as before wetting. The loss in 

 weight for different periods is shown in the followiog table: 



Loss in weight of wheat sprouting for different lengths of time.

"Aside from the loss iu weight which occurs iu the sprouting of wheat, marked 

 cliemical changes are brought about which decrease greatly the value of the article 

 for bread-baking purposes, and probably, also, as a food for stock. 



"The importance of protecting the wheat by proper stacking or storing iu barns 

 as soon as possible after it is ripe and dry is, great. The expense of stacking will 

 often be small as compared with losses which may occur by attempting to wait till 

 a machine cau be procured for the purpose of thrashing direct from the shock." 



Composition of the ash of ^vheat and its mill products, G. L. 

 Teller {ArMnsas Sta. Bui. 42, pp. 70-72, 75-80). — Complete asli anal- 

 yses were made of the whole wheat, the flour, and other milling products 

 from one of the milling tests mentioned above. The results are shown 

 in the following table : 



Ash oftvinter wheat and its milling products. 



Sodium oxid was not found in the ash in any case. 

 The presence of alumina iu wheat has been attributed to the wearing 

 down of the millstones. 



"This could not have been a source of the material iu these mill products, as the 

 wheat Avas crushed entirely by irou rollers, and an examination of the amounts of 

 alumina found iu the mill products and in the whole grain iudieate that it is no 

 more foreign to the true ash than any of the other constituents named. To bring 

 further proof on this pomt, 100 gm. of the unground wheat was carefully washed 

 with distilled water, and after drying, was burned without being pulverized. The 

 same amounts of both alumina and zinc were found as in the wheat which had not 

 been washed. It seems a little remarkable that the zinc should have accumulated 

 to the greatest extent in the ash of the bran while the alumina and silica should 

 have reached their largest proportion in the ash of the finer flours. Alumina is 

 found to be of frequent occurrence iu the mineral waters of this State."
