crops, samples of different kinds of soil found in loAva with a statement 

 of nitrogen and phosphorus content, a large soil map of the state made of 

 soil brought from the different counties and laid off in counties so that 

 the variation in soils could be seen at a glance. There was a collection of 

 the different insects injurious and beneficial found on the farm, varieties 

 of grain from a number of the county farms, devices for the purpose of 

 testing seed corn, a large plat showing how to make a test of individual 

 ears, and charts showing the yield from individual ears. There were also 

 charts showing the crop production by different counties, and a large 

 amount of statistical information of general interest. In the horticultural 

 booth insect pests at different stages of their life history were shown, as 

 well as spraying materials and apparatus. Samples of posts from different 

 varieties of wood and treated by dipping in pres.ervatives were shown; 

 also creosote blocks. In the dairy department was a map showing the lo- 

 cation of the creameries in Iowa, fat testing machines, moisture test 

 for butter, samples of a daily record sheet for keeping the weight and 

 test of individual cows, etc. The department of farm engineering ex- 

 hibited a model farm power plant, with a small gasoline engine running 

 a churn, washer, separator, and other small farm machines. Small models 

 of concrete and tile silos were shown; also a great variety of different 

 sorts of horse shoes, farm tools, etc. In the booth occupied by the highway 

 commission were models of concrete culverts, bridges, and specifications 

 showing the cost of constructing them. It is unfortunate that this college 

 exhibit was not located in a more conspicuous place.
