should be fairly representative of the whole state. These 

 samples were taken in tubes which were constructed especially 

 for our purpose, and are of steel bicycle tubing, eight inches 

 long and one inch in diameter. Whenever possible, the earth 

 was removed in a crust of an inch or less in thickness, and 

 the tube forced into the ground beneath, to a depth of four or 

 five inches. About one inch of dirt was removed from the 

 tube with a sterile knife, and the cotton plug readjusted. On 

 being returned to the laboratory the samples were transferred 

 to sterile four ounce salt-mouth bottles, thoroughly mixed, 

 and soil taken therefrom as desired. Experience has abund- 

 antly proven that the whole process of sampling, transfer, etc., 

 can be performed with such exactness that no contamination 

 takes place.

No more samples were taken at one time than could be 

 handled with promptness, therefore necessitating several trips 

 over the state.
