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 8 1 '.3" and evening 91' .3" 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 eontinued.
