were washed with distilled water until all their free soluble salts were 

 eliminated and then samples of these washed soils were placed in glass 

 tubes, then water content was brought up to the ratio of 1 of soil to .7 

 water and then freezing point depression determined as usual at various 

 intervals. The results obtained are tabulated in table 22. The typical 

 results of a few soils are graphically represented b}^ figures G to 10 

 inclusive.
