SEVENTEENTH ANNUAL YEAR BOOK — PART IV 305 



One of the new implements to be found in the machinery exhibits 

 was a road scarifier. The Iowa Higliway Commission had this at their 

 headquarters. Several of these scarifiers have been in use on gravel 

 roads this summer, and the commission is very enthusiastic in regard 

 to its qualities. A gravel road, after it has become hard and packed, 

 often gets wavy and uneven. The scarifier, which is attached to a road 

 grader, simply scars the gravel, after which it is leveled with a grader. 

 One of these scarifiers was used on gravel roads at Eagle Grove re- 

 cently, two engineers of the commission being present to look into its 

 merits. It took lots of power to rip up the packed gravel, but after 

 it had been leveled, a smooth-surfaced road, free from bumps, was the 

 result. With the more extensive building of gravel roads, it is probable 

 that these scarifiers will fill a prominent place in the maintenance of 

 roads of this type. 



Twenty thousand fish, which were mostly croppies; several hundred 

 pheasants; a display of fancy colored birds and swans, constituted the 

 exhibit made by E. C. Hinshaw, Iowa's fish and game warden. The 

 department this year has done a great deal of rescue work by seining 

 fish from lakes and ponds which threatened to go dry, and by placing 

 them in rivers. In this way, between 75 and 100 cars will have been 

 rescued, deputies frequently getting 20,000 fish a day from shallow 

 water. About 5,000 ring-neck pheasants have been distributed in dif- 

 ferent game preserves scattered over the state this summer. The hatch 

 from those put out a year ago is very satisfactory, according to the 

 deputy game wardens. 



AT THE COLLEGE BUILDING. 



Each year, the State Agricultural College, at Ames, prepares an edu- 

 cational exhibit for the state fair, and thousands find it interesting to 

 climb the hill to visit the building turned over to the college for this 

 purpose. The college display this year was different than usual, and 

 far better, although there might not have been quite so much of it. 

 In the past, a great many lessons could be carried home if one would 

 stop to copy down some of the data posted throughout the building. 

 Few would take the time to do this, so this year it was arranged so 

 that the information could be distributed in the form of printed cards 

 which fit the pocket. Hundreds of sets of these printed slips were 

 taken away, and it is probable that long after the fair is past, they 

 will be a source of reference and information. 



One of the cards emphasized the importance of good health as an 

 essential of good living. The lesson pointed out the necessity of a 

 pure water supply, and the need of taking care of garbage. It urged 

 that more attention be given to diet, and that this include plenty of 

 milk from healthy cows, eggs, fruit, and vegetables. 



A valuable lesson in landscaping was given in one of the exhibits, 

 and the arrangement of an ideal home yard was suggested in a model 

 that had required much pains in its preparation. The barn, poultry, 

 hog and other buildings were at a convenient distance from the house, 

 which stood the proper distance from the road. The view from the
