therein at least three inches under the surface^ 

 the tongue should be gently twisted sideways

 made, let the whole have a moderate watering 

 to settle the mould, and be set or plunged in a 

 good growing heat ; as it is of considerable im-

There are many plants which produce roots

 acquainted with by their natural efforts, and 

 therefore, will find it sufficient for their increase 

 merely to insert them in the mould : noting

 ments, that the layer, which is inserted to a 

 proper depth, roots sooner and better than that 

 which is layed near the surface ; the self-evident
