Tree — An arboreous or arborescent plant

Trench'ing— In a garden this is always 

 necessary, so a simple mode of per- 

 forming the work may be given. Open 

 a trench about two feet wide, one full 

 spit, and the shovelling deep, and 

 remove the soil from it to where it is 

 intended to finish the piece ; then put 

 in the dung, and dig it in with the 

 bottom spit in the trench ; if the 

 ground is very hard, break up with a 

 pick before putting in the dung ; then 

 fill up this trench with the top spit of 



the second, treating it in like manner, 

 and so on. The advantages of this 

 plan of working the soil are— The good 

 soil is retained at the top, an important 

 consideration where the subsoil is poor 

 or bad ; the bottom soil is enriched 

 and loosened for the penetration and 

 nourishment of the roots, and, allowing 

 them to descend deeper, they are not 

 60 liable to suffer from drought in dry 

 weather ; strong soil is rendered cap- 

 able of absorbing more moisture, and 

 yet remains dry at the surface, by the 

 water passing down more rapidly to 

 the subsoil, and it ensures a thorough 

 shifting of the soil. 



Tri, in compounds, signifies three, as
