EXHIBIT OF TREE PLANTING ON A MODEL PRAIRIE FARM AT THE 

 LOUISIANA PURCHASE EXPOSITION. 



THE FARM. 



The model farm forms part of the open-air exhibit of the Bureau 

 of Forestry at the Louisiana Purchase Exposition, and is designed to 

 illustrate the use of forest trees for windbreaks, hedges, and woodlots 

 in the Prairie States. It comprises a tract 264 feet square, laid off to 

 represent a southeast quarter section reduced on a scale of one-tenth 

 the actual linear measurements. The model shows, therefore, a prac- 

 ticable arrangement of fields, farmstead, and forest plantations on a 

 prairie farm of 160 acres, all of which is tillable. The relative loca- 

 tion and extent of woodlot, hedges, and windbreaks have been care- 

 fully planned with reference to actual needs and conditions. The field 

 crops are arranged in accordance with a plan of rotation suitable to 

 the Middle West, the details of which are explained in a circular issued 

 by the Bureau of Plant Industry. 



HEDGES AND FIELD BOUNDARIES. 



In accordance with the common practice of the Prairie States, the 

 public roads run on the section lines. They represent a width of 4 

 rods. Lines of shade trees planted at 4-foot intervals, corresponding 

 to 40 feet of actual distance, stand in the edge of the public highway. 

 The farm is bordered on all four sides by hedges of Osage orange a 

 tree which, in spite of the considerable prejudice against its use in 

 many parts of the Middle West, has such advantages for windbreaks 

 and other protection as far to outweigh the objections brought 

 against it. 



The farmstead, providing for the location of the house, barns, yards, 

 orchard, garden, etc. , occupies the southeast corner of the farm, and 

 is separated by hedges of Osage orange from the adjoining fields on the 

 west and north. The north and south hedge is prolonged to the north- 

 ern boundary of the farm, setting off field A, north of the farmstead, 

 from fields B, C, D, E, and F, which run east and west in equal 

 strips across the remainder of the farm and are separated from each
