146 MAINE AGRICULTURAL EXPERIMENT STATION. I914. 



The threshing machine used is the so-called Baby Vibrator, 

 made by the A. B. Farquhar Company. This machine has a 12 

 inch cylinder. In threshing a series of small plots containing 

 different varieties it is necessary to see that the machine is 

 thoroughly cleaned after each plot. If this is not done the vari- 

 eties very soon becom.e badly mixed. In order to facilitate 

 cleaning it has been necessary to remodel this machine in sev- 

 eral respects so that now it is possible to open up all parts of 

 the machine and remove any lodged grain after threshing each 

 plot. 



RECORDS. 



An important element in this kind of experimental work is 

 the keeping of accurate notes about each variety. To facilitate 

 this work we have devised a system of printed loose leaf blanks.

Figure 54 shows a facsimile of the Plot Record blank. This 

 blank, which may be used for any crop, provides for the size of 

 plot, fertilization, seed used and for general notes about the 

 plot.
