90 PRACTICAL FOREST MANAGEMENT. 



been recorded. The marking with whitewash is usually done by 

 separate workmen allotted to an individual calliperman. When 

 the other end of the compartment or enumeration section is 

 reached the line turns and measures a strip adjacent to the one 

 already done. The marks on the trees counted should be placed 

 on the side of the tree facing the direction in which the work will 

 progress so that when working in any strip the marks on the trees 

 of the last strip are clearly visible. In most cases a man carrying 

 drinking water for the gang will have to be provided. 



Wherever possible the compartment to be enumerated should 

 be divided by clear physical features such as ridges, nalas or paths 

 into enumeration sections. The ideal section is one that can be 

 counted in one day, so that it becomes possible for the officer 

 responsible for the work to check the work of any one man in one 

 day. Such check is absolutely necessary and the permissible 

 percentage of error is a maximum of 5 per cent. If this is exceed- 

 ed the work of that recorder must be rejected and the man 

 dispensed with. As a matter of fact, the percentage of error found 

 on checking is normally very much less than 5 per cent. On 

 completing each section or compartment the recorder hands in his 

 results to the working plan officer or the assistant in special charge 

 of this work after signing the form. Recorders usually work in 

 separate sections or compartments, they have however been 

 concentrated in one section spread out in a long line, this was 

 found of advantage on difficult ground as complete supervision by 

 a responsible man was then possible. A standard day's task should 

 be fixed by the working plan officer and the work kept up to this. 

 The custom of recording trees as sound or unsound in the enumer- 

 ations has been found by past experience to be most unsatis- 

 factory and to have served no useful purpose. Trees obviously 

 worthless should be omitted from the count, trees which, fork below 

 broast height are counted as two trees. The recorder must 

 see that the calliper is properly applied to the bole, the rule 

 of the calliper should touch the stem and the measurement*
