THE WHEAT CULTUEIST. 



from a winter, to a spring grain that the plants will not 

 endnre severe freezing. Spring wheat of this charac- 

 ter, should never be sowed until the ground has become 

 thoroughly warmed. This accounts for the fact, that in 

 numerous instances, certain farmers have always had 

 better success when they have sowed their spring wheat 

 quite late in the spring. On the contrary, when a va- 

 riety of spring wheat is still so much of a winter wheat, 

 that freezing does not injure the young plants in the 

 spring, the seed should be put in as early as practica- 

 ble ; and the crop will be the better for early seeding. 



These thoughts will explain why it is best to sow 

 spring wheat very late, sometimes j and early in the 

 growing season, at other times. A farmer must know 

 his seed — of what sort it is. Then, he must understand, 

 most thoroughly, the habit of growth, and how far the 

 variety has been changed from a winter to a spring 

 grain. When he possesses a perfect understanding of 

 these" points, he will experience very little difficulty in 

 growing fair crops of spring wheat, provided his seed is 

 right. (Read pages lYO and 171.)
