Experiment I. 
In this experiment the single incision comes out best, but each 
group so tapped were large and outside trees, and for large trees, 
gnarled and hard, the single incision will always be a convenient 
method. 
The difference between morning and evening tappings is not 
conspicuous, a matter of 2 ozs. only, but the aggregate girths were 
morning 81/.3" and evening gi'.f and also workman No. 4 spoiled 
his morning tappings the reversed oblique incisions being much too 
close, and with his evening tappings, single incisions, he had the 
luck with tree 27 which, in respect of yield, surpasses any other 
tree I have observed. 
For the sake of uniformity, the experiment ceased as soon as the 
simple incisions were completed, and these, No, 5 morning and 
Nos. 4 and 5 evening, represent completed tappings. 
The reversed oblique incision shows no advantage over oblique 
incisions and has not been continued.
