Experiment II. 



A very interesting experiment, the finest lot of trees whs un- 

 doubtedly No. 3 morning, whose best tapping was 13 ounces and the 

 1 8th tapping 10 ounces. Single incisions comes out very poor and is 

 in each group the lowest result. 



After 14 tappings it was necessary to stop or the trees would have 

 been scored too severely. It may be thought 10 cups on each tree 

 were too many, I do not think so, see Experiment III, Number IV. 



The advantage of tapping on alternate days is shewn in the dif- 

 ference between Nos. 1 and 2, both in morning and evening tap_ 

 pings. It will be noted that No. 2 morning was tapped 18 times 

 against 16 times of No. 1.
