the vines cover the ground. In the fall, the vines should 

 be mowed and w r hen dry worked into the soil with a 

 disk harrow. The fertilizers used for young trees and 

 spring application on bearing trees should have an or- 

 ganic content. This should be of tankage or Peruvian 

 guano not cotton seed meal. By this method of culti- 

 vation the land will become heavier and darker and less 

 thirsty every year, for the humus content will be in- 

 creased. In starting young trees special attention should 

 be paid to establishing a deep root system. With all 

 these precautions, undoubtedly the difference in growth 

 and fruit secured by irrigation would make an irriga- 

 tion plant a most profitable investment. 



Heavy, Wet Land A direct opposite condition to the 

 above is found in the groves w r here the water table comes 

 within three feet of the surface. A natural growth of 

 grass soon occurs on such land and this is allowed pos- 

 session of the middles. Circles should be hoed around 

 the trees and covered with heavy mulching. Strictly 

 chemical fertilizers are adapted to this soil. They can 

 be spread broadcast and left for the rains to carry down ; 

 there will be no waste. All the land will have to be 

 worked for about three years after clearing to reduce 

 the virgin growth and to secure right physical condi- 

 tions, but great care must be taken not to puddle the 

 soil by disturbing it when too wet, especially in hot 

 weather. Such land invariably needs extensive drainage, 

 and even then w r ould be too wet during the summer rains 

 were it not for the vast amount of w r ater thrown off by
