316 GARDENING FOR THE SOUTH. 



White Norfolk is another large field sort ; both are good 

 varieties, and much cultivated South, both for their roots 

 and for winter greens. 



Yellow Dutch is very hardy, more so than the forego- 

 ing. Sweet, fine-flavored, and very nutritious. It is of a 

 yellow color, round, handsome shape, firm and sweet, and 

 keeps well. 



Yellow Aherdeen is perhaps the same as the last. 



Ruta Baga, .OF Swedes Turnip is a different variety, 

 (JBrassica campestris var. ruta baga^) of which the foliage 

 differs from those preceding in being smooth and covered 

 with glaucous bloom. There are several varieties, all 

 hardy and good. 



Pu-rple-topped Swede, The roots are very large, of an 

 oval, tapering form, and the greater their size, the sweeter 

 and more nourishing they become. It keeps until spring. 



Skirving's Improved Swede, This is of still better 

 form than the foregoing, the leaves not so large, less 

 smooth, and free from bloom ; flesh fine, yellow, and very 

 nutritious. 



Sweet German Turnip, Called also White Ruta Ba- 

 ga and Cabbage Turnip, (Brassica campestris JVapa 

 Brassica, D. (7.,) resembles the last two, but the flesh is 

 white, very sweet, with somewhat of the cabbage flavor, 

 and is a good keeper. Roots large, but not as regular as 

 the preceding. 



It is found that the most important fertilizer is phos- 

 phate of lime. Either bone dust, superphosphate of lime, 

 or guano, all rich in phosphoric acid, seems to supply 

 everything this crop requires. Manured with either of 

 these, it is soon beyond the reach of insects and casualties. 

 For the spring crop guano or manures rich in ammonia 

 are essential, but for the autumn crop the superphosphate 

 of lime seems to act more beneficially than any other ap- 

 plication. Manipulated guano, honestly prepared, is valu-
