time of sowing, and that lience no definite date can be given. Of the varieties under 

 test for 3 years, KeHaljle has jtroduceil the most grain. In 1900 this same variety 

 was again the leader in j^roduetiveness, followed by Dawson Golden Chaff, the yields 

 being 22.29 and 17.64 bu. per acre respectively. 



The comparative values of Ontario wheats for bread-making purposes, 

 R. Harcourt ( Ontario Agr. Col. and Expl. Farm Bui. 115, pp. 6) . — For the purpose 

 of making this comparison 37 ten-bushel lots of wheat were gathered from different 

 sources. All lots were grown in Ontario in 1900, with the exception of a l(jt of 

 Turkey Red imported from Kansas. These lots were ground and the tiour saved 

 from the last part of the run to assure the accuracy of all samples. The results of 

 the work are set forth in the following table:

In connection with this report the value of heavy and light wheats, the importance 

 of gluten, the effect of baking, and the yield and quality of bread fnjm flour are 

 discussed, and notes on environment, season, soil, fertilizer, locality, and change of 

 seed, so far as these factors influence the bread-making value of wheat, are given. 



Varieties of winter wheats, C. A. Z.witz {Ontario Agr. Col. and Expt. Farm 

 Bui. 115, pp. 7, 8). — This report presents the results of tests with 40 varieties of win- 

 ter wheat, the most promising of 94 kinds tested for 5 years or more on about 800 

 different farms. These include 20 bearded and 20 beardless varieties, 32 of which 

 are red and 8 white sorts. The average results of these different groups are given in 

 the table below.
