EXPERIMiENT STiATION REPORTS. 225 



UXrUDLISHED DATA. 



The manajiemeiit of farms in the Detroit wliole milk area has been 

 a subject of intensive study since the (le])artment was or<>anizeil, and 

 preceding that time the Dairy l^epartment had carried on route work 

 for two years on 50 farms to determine the cost of producing market 

 milk for Detroit. There are, therefore, three years of unpublished data 

 covering the farming section of tlie State commonly known as the Detroit 

 Milk Area. This data is now being prepared for publication. 



There is also a year's record completed on each of 07 farms on three 

 other types of farming; namely, general farming in Central Michigan, 

 potato farming in the northern part of the State, and feeder farming in 

 the southern portion. These records were completed in April and are 

 now in the process of compilation. 



An extended study has also been made of units in farm investment 

 with the purpose of working out basic facts that farmers may use in 

 arriving at conclusions about investments with which they have had little 

 or no experience. 



An amount of data for the use of high school teaclier.s of Agriculture in 

 teaching farm accounting has been assembled, mimeographed, and dis- 

 tributed to a group of such teachers. This work has been done in co-oper- 

 ation with Mr. E. E. Gallup, State Supervisor of Agricultural Instruction. 



A limited survey of Farmer's Mutual Insurance Companies has been 

 made during the year by Mr. I). T. Musselman.

College. 

 Dear Sir: 



Following is a report of the experimental and investigational work of 

 the Farm Mechanics Section for the year 1021-22. 



The woTk of this Section is reivorted under three major groups of work. 

 Farm Buildings and Conveniences, Farm and Power Machinery, and 

 Drainage and Land Ctearing. 



Increased interest in building within the last six months has brought 

 new angles on the building problem. Mr. Fogle has continued the study 

 of barn plans and had hoped to have them ready for publication before 

 this. Study of potato and root storage warehouses was begun two years 

 ago. The last year there has been considerable demand for this material. 

 When potatoes are stored in large quantities the need of some means of 

 control of temperature and humidity of the air has become apparent. 

 Insulation of the building and control of the air movement within seem
