 stem. On the other hand, it admits of the most complete 

 utiHsation of the Ki"ound between the lines, and facilitates 

 thinnings and the removal of the material ;• the i)lants are 

 also easier to find. 



On the whole, these advantages and disadvantages are not 

 of much importance, because after the early thinnings the 

 three forms stand practically on the same footing. Many 

 foresters prefer line planting to the two other forms, because 

 it is easiest to carry out, and perhaps the cheapest. Others

prefer the square form, while the triangular form is perhaps 

 less frequently chosen. 



The marking of the planting spots is done with two lines 

 (or chains), the so-called directhuj liitr and the planthifi line. 

 The latter is divided according to the planting distance, each 

 division point being marked in a suitable way, either by a knot, 

 or by drawing a coloured tape through it. On the directing 

 line the distance between successive rows is marked in a 

 similar manner. In the case of square planting the marking 

 is the same on both lines, but different in triangle and line 

 planting. In the latter each division of the directing line is
