DEPARTMENT REPORTS. 65 



Instruction in the several courses given by the department may be 

 summarized. The number of students receiving work is as follows: 



Farm Structures 60 



Farm Conveniences 24 



Power Machinery 99 



Farm Machinery 43 



In the short courses the numbers are: 



Building Designing 53 



Farm Engineering 50 



Wood Work 147 



Forge Work 148 



Creamery Mechanics 19 



Gas Engines (Horticultural) 13 



Practical work was done by the class in Farm Conveniences. One of 

 the problems worked out was tlie construction by the class of a concrete 

 manure pit for the Bacteriology department barns. A new and much 

 needed course in Farm Drainage is to be added next year. This course 

 will present work which is of particular interest on the farm considered 

 as a unit. 



INVESTIGATION. 



Many inquiries concerning methods of removing marl from submerged 

 beds has brought tliis problem to our attention. Some thought has been 

 given the problem for two years or more. Last spring, however, the 

 interest in this was greatly increased, and Mr. D. H. Flower was engaged 

 to work on the problem. No practical results have been attained as yet. 



Much valuable information is still being collected by the Extension 

 Eepresentative in Household Engineering on sewage disposal. An effort 

 has been made to keep in touch with tractor development. There are 

 now one hundred and fifty different sizes and types of tractors to be had, 

 though none have proved their place in more than a limited way. 



EXTENSION. 



The work in Extension has been confined quite closely this year to 

 Household Engineering, a report of which is made under the Extension 

 division by Mr. O. E. Kobey who has had charge of this work. With 

 the call for greater production last spring, the work in Household En- 

 gineering was reduced and work in drainage taken up. The interest in 

 drainage has increased wonderfully and provision should be made to 

 meet this increasing demand. About 250 sets of blue-prints on various 

 subjects principally barns and other farm buildings have been sent out 

 besides those handled by the Extension representative. Greater demands 

 are being made on the department for information and great opportuni- 

 ties are ahead if these demands can be met.
