FIFTEENTH ANNUAL YEAR BOOK— PART IV 257 



On the west side of the building, Professor Buchanan, in charge of 

 the cooperative experiments for the college, has his exhibit. He arranges 

 with those farmers who so desire to make cooperative experiments. For 

 instance, he will send out a small amount of improved varieties of wheat 

 or oats. Or he will give direction for an experiment with limestone or 

 rock phosphate. By talking with men like this farmer visitors to the 

 fair this week are learning many new things. 



The wireless telegraph at the Iowa State College building was a new 

 feature. The click of the Instrument which flashed messages from the 

 fair grounds to city newspapers could be heard for long distances. This 

 was said to be the first use ever made of the wireless telegraph for news- 

 paper purpose in Iowa. Demonstrators were on hand to explain the 

 principles of wireless telegraphy, and the sending station was a point 

 of general interest to hundreds of visitors daily. 



One exhibit shows the different varieties of knots; another common 

 Iowa weeds; and another some of the plants which may some day be 

 grown on Iowa farms, but are not grown much as yet. For instance, 

 there are specimens of field peas, soy beans, cowpeas, sweet clover, Ger- 

 man millet, Hungarian millet, common millet, Japanese millet, and barn- 

 yard grass. By careful examination of these different exhibits it is 

 possible for one to learn many new things. 



In the poultry building the poultry department of the Iowa Agricul- 

 tural College gives demonstrations every day of caponizing, killing poul- 

 try and dressing, handling eggs and grading them for market. Exhibits 

 indicate the difference between the grade of eggs known as selects, the 

 grade known as firsts, and that known as seconds. The selects sell for 

 five cents more per dozen than the seconds, and for from one and a half 

 to three cents more than the firsts, and it is the object of the poultry 

 demonstrator to bring about the marketing of as many high-grade eggs 

 as possible in Iowa. He wants wide-awake creameries to establish egg 

 departments. He has been greatly encouraged in this work because one 

 Iowa creamery, in taking this up, has managed to make $600 in six 

 months over what the eggs would have brought if marketed in the ordi- 

 nary way. Tlie poultry demonstrator is worth talking to. He will tell 

 you about the advantages of the different models of poultry houses that 

 are on exhibit and the best ways to kill lice and mites. 



In past years the state fair grounds have been policed by several 

 hundred civilians from various parts of the state, whose appointment 

 was secured for them by their friends among the officers of the state fair 

 management. This year the management arranged with the state militia 

 to furnish two companies of guardsmen for this duty. In their neat
