next lower incision, and from there on to the following, etc., until 
reaching the lowest, where it is collected, as explained ‘further on. 
“ (2.) The incision is extended to the same height of the trunk 
as indicated in the first method, but is continuous, and consists of 
cuts, one ecke to the other, always ta iking care never to 
cut into more than two-thirds of the tree's circumference, thus 
leaving one-third of the bark intact. 
“Tt is useless and even dangerous to make the incisions so deep 
as to penetrate the woody part of the tree. On the contrary, great - 
caution should be exercised to preserve the fibres closest to the
