The fap thereupon fhlfts it*s otherwife def- 

 tin'd employment, and feeks, and flies to the 

 crowd of little port holes next adjacent in 

 the bark, in order for ligneous produdllons 

 of another kind — And even where fuch co- 

 hsefion of the bark is not over great.; by 

 what means foever the elaftic airy flatus in 

 the fap becomes over violent, it may alfo 

 be driven to the unnatural ufing of the a- 

 forefaid means. But more of this in the fe- 

 quel. For it follows firfl: I fhould fubjoin to 

 a topic before mentioned, that in regard to 

 the number of boughs at firfl: trial, to be 

 debarked^ great care is to be taken not to 

 exceed therein ; and it is no lefs proper to 

 intermit two years at leafl:, before fuch fur- 

 ther attempt is made on the fame trees. 

 Tho' no doubt improvements may be made 

 on my prad:ice, it may not be improper to 

 intimate, that I never exceeded three boughs 

 in number the firfl: operation — nor debarked 

 any more on the fame trees, till the third 

 fpring after — at which time alfo, I never 

 made freer than to debark two more — for 

 what caufe may be readily apprehended, at 

 leafl: will be readily found, on any young 

 operator's overdoing : After which I moftly 

 refl: three years, before I debark any higher 

 I boughs^
