The choice of a tapping system was considered from an economic aspect. An analysis was made of cost price and tapping labour. Suggestions were advanced to change the tapping system on the ground of this labour analysis.
At that time the trend of development of the tapping systems was still towards less damage to bark. Economic considerations had little influence on the choice of tapping system. But sometimes less frequent cutting was more profitable, even more so on occasion by larger cuts.
