The first of these trials with Blue Stem in Aroostook resulted 

 in a loss of protein of nearly 4 per cent; yet on the following 

 year a planting from the same seed and another from the original 

 Minnesota wheat brought the protein back to within one per cent 

 of the parent wheat. What the result from another planting 

 might be, it is impossible to predict. 



Equally inconclusive are the results obtained with the Minn. 

 181 wheat. This variety planted in Maine lost over 3 per cent 

 in a single season ; planted in Minnesota, it lost over 4 per cent. 

 The Minn. 851 lost no protein when grown in Aroostook, 

 although the western grown crop experienced a slight reduction. 



These curiously varying results seem to admit but one safe 

 conclusion, viz. : That merely temporary or extremely local con- 

 ditions of season and soil may obscure or counterbalance a ten- 

 dency the existence of which can be fully established only by
