THE CONDUCT OF ENUMERATIONS. 



89 



classes have been adopted in the United Provinces and each 

 diameter class has been given a corresponding colour on the calliper 

 for enumeration purposes, vide the Forest Pocket Book. 



Diameter class 



The extent to which the growing stock is to be enumerated 

 having been determined, it now remains to carry out this work. 

 At the outset it is laid down that in working circles organised on 

 a periodic block system, in which the yield is calculated by volume 

 for the regeneration area and by area elsewhere, a complete or very 

 nearly complete enumeration of the 'regeneration area must be 

 made. In forests where the yield is regulated by area, no enumer- 

 ations are generally necessary, but in special cases where an 

 accurate forecast of the probable outturn is wanted they may have 

 to be carried out. 



The actual counting of the trees is done as follows : 

 Each recorder is given a book ruled in the standard diameter 

 classes already mentioned, and two or at the most three calliper 

 men work with him. In the plains a couple of linesmen are also 

 necessary. Starting from the edge of the compartment a strip of 

 forest is taken along which the 2 linesmen walk tying bands of dry 

 grass along the line, but keeping pace with the rest of the gang. 

 The recorder takes up his position in the middle of the strip and 

 the calliper men measure at breast height and shout out the 

 species and colour of the trees on the callipers, the recorder entering 

 each tree with a dot under its proper species and Jcolour. After 

 each tree h5s been measured it is given a spot of whitewash in the 

 case of sal, or the bark is marked with a scribe or light axe in the 

 case of suitable species like cliir or deodar, to indicate that it has
