CULTIVATION. 



95 



in assisting the germination of cotton seed while, for the 

 after treatment of the cotton, the ridges make the crop 

 easier to lightly water and the bottom of the stems are 

 protected against repeated wettings. 



In January, nine days after watering, the north side of 

 a ridge contained 24*3 % of water, and the south side only 

 22' 6 %. The following table will sufficiently show the 

 difference in temperature of different sides of ridges. The 

 side temperatures were taken at four centimetres under the 

 surface the others at a depth of ten centimetres. It will 

 be noticed that the south side is always about four degrees 

 centigrade warmer than the north, and that the west is 

 slightly warmer than the east side.
