KNIVES. 



Garden knives are of various forms according to 

 the purposes for which they are used. In all cases 

 where a ('lean cut is required they should be of the 

 best quality that is, of well-tempered, steel, so 

 that they may take and retain a good edge when 

 sharpened. Pruning knives should be fairly strong, 

 with a buckhorn handle and a curved blade for 

 rutting large branches when necessary, and for 

 removing spurs and dead snags from fruit trees. 

 Propagating and budding knives should be lighter, 

 but of the best quality, with an ivory handle and 

 a straight blade, rounded off at the point in the 

 case of those used for budding. Knives for cutting

A genus of hardy annuals (ord. Chenopodiacerc),

 plant for the cool conservatory, as it has delicate 

 Fern-like foliage and grows to a height of 2'. 

 The flowers are greenish white and inconspicuous. 

 The foliage, which is soft green in summer, 

 becomes rich red in autumn (seep. 4U4).

KOHL RABI. 



The Turnip-stemmed Cabbage (Brassica oleracea 

 caulo-rapa) is also known as Knol Kohl and Cape 

 Cabbage (ord. Cruciferse). The stem grows to 

 various heights, according to the variety and soil, 

 tl>en swells out at the top in globular form, re- 

 sembling a Swede, with the leaves distributed all 

 over the sides and top. Propagation, by seeds in 

 beds from March to July for succession, and the 

 seedlings planted out when fit, 8" apart in rows IS" 

 asunder, the treatment throughout being precisely 

 like that given to Cabbages. Any well-manured 

 and good garden soil will suit them. The varieties 

 vary in size ami colour The very large forms are 

 grown in the field to feed cattle. Early Vienna 

 (un-rn) and Early Purple are good for table use; 

 and, if cooked when young, make a delicious veget- 

 able as a substitute for, or a change from, Turnips.
