Stove biennials ; sown in a hotbed, in spring, 

 or the end of summer, and carefully kept in 

 stove^ and greenhouses during the winter, they 

 will bloom early the following season.

Stove herbaceous perennials, with white 

 flowers. Cuttings, suckers, and division of the 

 roots ; sandy loam, peat, and decayed, but dry, 

 cow- dung. Summer temp., 60 to 80 ; winter, 

 48 to 55. If forced on in spring, they will 

 bloom in the greenhouse. The plants are 

 poisonous even to the touch, and should, there-

Hardy pea-blossomed yellow-flowered plants. 

 The annuals merely require sowing in the open 

 border, in March or April ; the herbaceous 

 trailers require dividing at a similar period : 

 bnlearica is the only shrub, it resembles and 

 requires similar treatment to the Coronilla, 

 needing a cold pit, or a greenhouse, in winter.

HOE. This is the implement which 

 should be most frequently in the gar- 

 dener's hand, for the surface of the 

 soil scarcely can be too frequently stir- 

 red. The handles should never be 

 made of heavy wood, for this wearies 

 the hand, and is altogether a useless 

 weight thrown upon the workman. It 

 is merely the level*, and every ounce 

 needlessly given to this, diminishes, 

 without any necessity, the available 

 moving power. The best woods for 

 handles are birch or deal. 



1 For earthing up plants, broad blades 

 to hoes are very admissible, and they 

 may, without objection, have a breadth 

 of nine inches ; but for loosening the 

 soil and destroying weeds, they should 

 never extend to beyond a breadth of 

 six inches, and the work will be done 

 best by one two inches narrower. The 

 iron plate of which they are formed 

 should be well steeled, and not more 

 than one-sixteenth of an inch thick. 

 The weight necessary should be thrown 

 by the workman's arm and body upon 

 the handle, and the thicker the blade, 

 the greater is the pressure required to 

 make it penetrate the soil. It should 

 be set on the handle at an angle of (in , 

 as this brings its edge at a good cutting 

 angle with the surface of the soil, and 

 the workman soon learns at what point
