10 HATCH EXPERIMENT STATION. [Jan. 



This serves as a work room in connection with pot experi- 

 ments. We have this year carried on experiments with 

 potatoes, onions, soy beans, corn and millet as crops, in 

 which we have used 286 pots. The results are of much value, 

 having assisted toward the solution of a number of important 

 problems ; but, as there remains much chemical work to be 

 finished in connection therewith, these experiments cannot 

 be reported at this time. Of the value of this method of 

 experiment, which has so approved itself with European 

 investigators, there can not be the slightest doubt ; it will 

 prove a most important adjunct to field work. 



We have further carried out a number of experiments in 

 cylinders 4 feet deep and 2 feet in diameter (without bot- 

 tom), plunged to the rim in the open air and filled with 

 equal amounts of carefully mixed earth. In these experi- 

 ments we have employed sixty-three such cylinders, dealing 

 with some important problems. This too proves a valuable 

 method of work. Results are not yet sufiiciently worked 

 out for publication. 



The report will touch in detail only upon experiments the 

 results of which are sufiiciently definite to permit practical 

 deductions of value. The report on such experiments 

 follows. 



Soil Tests. 

 Two soil tests have been carried out upon our home grounds 

 during the past season, both in continuation of previous 

 work upon the same ground. The same kinds of fertilizers 

 have been applied to each plot and in the same amounts as 

 last year. In addition, each plot in the first test received 

 an application of slaked lime, at the rate of one ton per acre ; 

 in the second test, one-half of each plot received an applica- 

 tion of lime at the same rate. The lime was spread evenly 

 early this spring, and harrowed in, both fields having been 

 ploughed the previous fall. 



Soil Test with Corn. Amherst. 

 The past is the eleventh season that the experiment on this 

 field has been in progress. The crops in order of rotation
