and deeper 













Of these trees, No. 2 grew in soil with a very compact 

 stony subsoil below 35 cm., and No. 3 in soil without 

 stone to a depth of 120 cm. The number of roots 

 calculated for the entire circumference of the tree, at 

 the distance at which the trench was dug, ranged from 

 592 (No. 1) to 2464 (No. 5). Very many counts of 

 this kind have been made at the College of Agriculture. 



No roots will grow to any distance into water, nor 

 into a level of the soil where free water stands ; and a 

 rise in the water-level ultimately kills the submerged 

 roots. Neither can they grow in very dry soil ; a few 

 centimetres of the surface is in most places dry so 

 much of the time that roots cannot grow into it. 

 Sand is drier than heavy soil, and the roots accordingly 

 maintain a deeper level in it. The best conditions are 

 obviously those which permit the growth of the most 

 ample root system. So the soil should be deep, and
