Nos. 30 and 33. Do not fail to turn to all these 

 pictures while you have this question in mind. 



Cut No. 40 is another demonstration of in- 

 creased fertility by summer tilling. Here are 

 five heads out of 31 from one grain or stool, and 

 there are 341 grains in the five heads or an 

 average of over 68 grains each. This is not only 

 remarkable but very unusual. There were four 

 grains in every group, a fact that is very un- 

 common. This was grown near Morcroft, Wyo- 

 ming, in 1915, on land that was summer tilled in 

 1914 and seeded, as we advised, with 20 pounds 

 per acre. By an unavoidable combination of 

 conditions the seeding was done late, therefore, 

 very little stooling in the fall. The field started 

 off in the spring seemingly so thin that the 

 owner decided it worthless and plowed up about 

 two-thirds, leaving the balance to prove that 20 

 pounds was not seed enough, but to his amaze- 

 ment he cut from this small field, what he ad- 

 mitted to be the largest yield per acre of the best 

 wheat he ever saw. The five heads referred to 

 were from this field. This is seemingly evidence 

 in favor of the correctness of three principles or 

 theories; first, that tillage of the right kind at 

 the right time is a greater factor in influencing 

 growth; second, that with ample available plant 

 food, plants are much aided in that all important 

 continuous growth that brings the big yield; 

 third, that thinner seeding for the more ideal 

 seed bed that is supplied with a liberal amount 

 of available fertility is of great importance. The 

 story also brings out the interesting fact, that
