THE DATE PALM. 



stem. The tips of the deepest of these penetrated to a depth of 7 

 to 9 J feet. The permanent water-level in the locality is at a depth 

 of about 80 feet. The tree was irrigated when necessary from a 

 small water channel which passes within 4 yards of it and flows 

 about once a week. One root followed up in another tree planted 

 as a sucker in the Taleri Bagh. Muzaffargarh, five years previously, 

 was 25 feet in length, and ended at a distance of 18 feet from the 

 parent tree. 



With the exception of a comparatively few roots which spread 

 out more or less horizontally, the root-system of the five years old 

 date trees examined in the Taleri Bagh were contained within 

 a radius of 6 feet from the parent stems. The roots ended at 

 depths between 2 and 6j feet. The subsoil water-level at the 

 time of examination was 7 feet below the surface. In the case 

 of older trees in the same vicinity date roots were followed up to 

 Ij feet under the permanent water-level. In view of the special 

 internal structure of the root (see above, same paragraph) this 

 was to be expected. 



The root-system of a date tree planted near Lyallpur 

 21 years previously was examined. The soil was a medium 

 loam. The permanent water-level was 80 feet deep, but there 

 is a large perennial canal 50 feet wide running at a distance 

 of 160 yards from it. About 26 feet from the tree a small 

 channel about 3 feet wide runs almost continually. 



The following data were got :
