place of that which the crop of the past : 

 season may have in some measure , 

 exhausted. 



Bastard-Trenching is thus performed : j 

 Open a trench two feet- and- a-half j 

 or a yard wide, one full spit, and the I 

 shovelling deep, and wheel the soil j 

 from it to where it is intended to finish 1 

 the piece, then put in the dung and : 

 dig it in with the botttom spit in the j 

 trench, then fill up this trench with the j 

 top spit, &c., of the second, treating it ; 

 in like manner and so on. The ad- 

 vantages 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 so liable to suffer 

 from drought in summer; strong soil 

 is rendered capable of absorbing more 

 moisture, and yet remains drier at the 

 surface by the water passing down J 

 more rapidly to the subsoil, and it | 

 insures a thorough shifting of the soil. 



In all trenching, whether one, two, j 

 or more spades deep, always, previous j 

 to digging, put the top of each trench 

 two or three inches deep or more, with 

 all weeds arid other litter at the bottom 

 of the open one, which not only makes 

 clean digging, and increases the depth 

 of loose soil, but all weeds and their 

 seeds are regularly buried at such a 

 depth, that the weeds themselves will 

 rot, and their seeds cannot vegetate.

All yellow - flowered, and annuals, except 

 Cistoides. Sow in a hotbed, in March, harden 

 off, and put in a sheltered place in the garden 

 towards the beginning of June, or flower in 

 pots in the greenhouse; rich, light, sandy loam ; 

 a little peat will be required for Cistoides, which 

 is easily increased by cuttings, in the spring.
