 that of the olive and poppy. Owing to the valuable property 

 belonging to the plant of enduring winter and spring frosts, it 

 may be sown either in autumn or in spring. The crop should 

 be reaped as soon as the earliest seeds acquire a grey colour, 

 and disposed in handfuls to facilitate drying, after which it 

 should be immediately threshed out, as, if stacked in the haulm, 

 the viscid matter which adheres to the foliage would cause 

 fermentation. The seeds should be afterwards washed in warm 

 water, to cleanse them from the same viscid, strong-smelling 

 substance." Professor Lindley says, " Madia sativa is a 

 Chilian plant lately introduced with success into the agricul- 

 ture of the drier parts of Europe. Madia oil, expressed with- 

 out heat, is described as transparent, yellow, scentless, &c., and 

 fit for salads. Its cake is said to be good for cattle." Mr 

 Lawson concludes some observations on madia thus : " There 

 seems every probability that in ordinarily favourable seasons
