The leaves from Plat II contained 27 per cent more lime, 23 per 

 cent more potash, 49 per cent more iron, and 35 per cent more silica 

 than the leaves from Plat I, and an equal amount of magnesia, 

 phosphoric acid, and nitrogen. The leaves from Plat III tliffered from 

 those of Plat I in containing 17 per cent more lime, 48 per cent more 

 iron, 27 per cent more silica, and 8 per cent more potash; the leaves 

 from Plat IV differed in containing 17 per cent more lime, 15 per cent 

 less magnesia, 22 per cent less phosphoric acid, and 22 per cent more 

 iron. 



The stalks from Plat II differed from those of Plat I only in con- 

 taining 10 per cent more potash; the stalks from Plat III differed in 

 contaming S per cent less lime, 13 per cent less magnesia, 14 per cent 

 more potash, 15 per cent less iron, 18 per cent more silica, and 26 per 

 cent less nitrogen; the stalks from Plat IV differed in containing 14 

 per cent less lime, 24 per cent less magnesia, 14 per cent less phos- 

 phoric acid, 9 per cent more potash, and 20 per cent less nitrogen. 



As the green weight of the stalks averaged twice the green weight 

 of the leaves, it can be seen that the lime content of the combined 

 leaves and stalks from Plat II was a little higher than that from Plat 

 I, while the lime content of the leaves and stalks from Plats HI and 

 IV varied little from the lime content of those from Plat I. The ash 

 constituents of the combined leaves and stalks of Plat II differed 

 from the ash constituents of the leaves and stalks of Plat I in contain- 

 ing about 10 per cent more lime, 15 per cent more potash, 20 per cent 

 more iron, and 15 per cent more silica; the combined leaves and stalks 

 from Plat III differed in containing some 8 per cent less magnesia, 10 

 per cent more potash, 20 per cent more iron, 20 per cent more silica, 

 and 20 per cent less nitrogen; the leaves and stalks from Plat IV 

 differed in containing about 20 per cent less magnesia, 17 per cent 

 less phosphoric acid, and 13 per cent less nitrogen. 



RADISHES. 



Long Scarlet Short Top ratlishes were grown to the marketable 

 size, which took about 30 days. Roots and tops were weighed 

 separately, but as the proportion of root to top was unaffected by 

 the different soils only the weights of the whole plants are given in 

 Table XIV.
