700 Agricultural Experiment Station, Ithaca, N, Y. 



United States; factory No. 18, Sharpies; and factories No, 7 and 

 11, Jumbo. It would seem, therefore, tiiat since it is possible that 

 machines of the various makes that will do perfect work can be 

 made, that it is due the operator to demand from the manufacturer 

 a gnarantee of such perfect work. 



EESULTS OF TESTS AT VAEIOUS STATIONS. 



As has been already noticed, several Experiment Stations have 

 made similar tests of various separators.* In the table below we 

 have grouped together the results of these tests, including both 

 those made at the Stations and those made at outside factories. 

 This table represents work done by live different Stations extending 

 over a period of four years, and including some hundreds of different 

 trials. It would seem that the average would indicate the efficiency 

 of separation that it should be possible to attain with an ordinary 

 amount of care and skill.
