CONTRIBUTIONS FROM THE WISLEY LABORATORY. 35 1 
germination is shown by the fact that no radish seedlings appeared 
on the plots subsequent to the harvesting of those present at the 
end of the experiment, though the plots remained fallow well into 
the autumn. 
The weather subsequent to the sowing was favourable to the 
growth of the radishes, and good crops were obtained from the plots 
dressed with pig manure when all the radishes were pulled and 
weighed on July 19. 
The results are shown in the following table : —
