TWELFTH ANNUAL YEAR BOOK— PART XI 573 



of aeroplane factories peace commissions will go out of business. War 

 will be simply impossible with these great birds of the air carrying high 

 explosives and flying at will by daylight or in the dark of night over cities, 

 fortifications and battleships. The enemy in the air will hold lives in 

 the hollow of his hand. 



There was no lack of entertainment features. In addition to the aero- 

 planes, which made two flights daily and could be seen from all parts 

 of the ground, there were the races and vaudeville stunts in front of the 

 grandstand by day, and an elaborate fireworks display at night. In the 

 stock pavilion a very good show was held each evening, while the seats 

 were filled by an interested crowd which watched the stock judging 

 closely. There were the usual side show attractions on the ground, not 

 particularly elevating, but not of the distinctly reprehensible sort. The 

 Iowa Fair management has for years exercised a close censorship over 

 side shows and concessions of all kinds. 



The Agricultural College had a fine exhibit, one of much value to every 

 farmer who inspected it. It is impossible to compute the money value of 

 an exhibit of this sort to the state of Iowa, but we would estimate that it 

 would run into the thousands of dollars. Besides this, many farmers 

 and farmers' boys received an inspiration to strive for the higher things 

 of farming that should stay with them for a long while. The extension 

 department at the Agricultural College is certainly to be congratulated 

 on the way in which it has learned to present graphically agricultural 

 truth. The extension department has been conducting dairy test asso- 

 ciations in the northern part of the state. The results are very inter- 

 esting. These were represented by what appeared to be huge blocks of 

 butter. One block labeled 430' pounds represented the butter yielded in 

 .one year by the best one of the 688 cows in the five dairy test associations. 

 A small block labeled 89 pounds represented the butter yield for the year 

 of the poorest cow in the associations. The best 200 cows in the test had 

 representing them a block nearly twice the size of that representing the 

 yield of the poorest 200 cows. The average yearly profit of the best cows 

 was $52, while that of the poorest was $20. One of the Holstein cows at 

 the dairy department of the Agricultural College produced in one day 

 fifty quarts of milk. Fifty quart bottles represented this fact, so that 

 the eye grasped it at once. There was no particular moral to this rep- 

 resentation, but it was interesting, especially to the small boys, some 

 of whom would make exclamations such as "Gee! Did one cow give all 

 that in one day?" If each of these quarts of milk could have been sold 

 at eight cents, the present retail price, the one day's milk of this cow 

 would have been worth $4. Her feed cost 25 cents. Butter-fat sufficient 

 to make 717 pounds of butter were piled in a pyramid. These repre- 

 sented the wonderful yield of butter made by a Guernsey heifer last year 

 at the dairy barns of the Agricultural College.
