232 THE BEAN CROP. 



often remain of a small size, though occasionally spread- 

 ing far and wide, especially when occurring on the stem. 

 Though, however, the red spots remain of small size, and 

 therefore comparatively innocuous, the disease does not 

 always cease entirely. Other spots of a brown tinge occur, 

 irregular in outline, but extending in concentric rings, so 

 as frequently to leave slight traces behind, and involving 

 in their course the smaller patches. Though the growth is 

 evidently concentric, the strictest search does not detect 

 any fungoid growth, as might at first be suspected. If 

 the brown patch extends to the stem, decay rapidly ensues. 

 This is not, however, always the case; but though the 

 crop looks miserable, the fruit may still be perfected, 

 though not without exhibiting here and there traces of 

 the disease in the shape of irregular brown spots affecting 

 the subjacent tissues. The disease described in the Gar- 

 deners Chronicle for 1851, is probably of a similar nature. 

 Supposing the disease to be arrested by weather unfavour- 

 able to its growth, another enemy now steps in, complet- 

 ing the exhaustion of the plant. We have now before us 

 specimens, in which not only are the leaves covered 

 with the red and brown blotches, but in which a third 

 set of spots occurs, snuff-coloured in the centre, and white 

 or pale in the circumference, the central mass consisting 

 of perfectly smooth, sub-globose, brown, stemless spores. 

 These are in fact due to the Uredo Fabce (De C). When 

 possessed by the three kinds of blotches at once, the crop 

 wears a very wretched aspect, and the prospect of the 

 farmer is by no means encouraging. It is well, however, 

 that proper precaution should be exercised before the crop 

 is utterly condemned. We have this year seen a crop of 

 winter beans which seemed in an utterly hopeless state, 

 and which were accordingly destined one fixed day to be 

 ploughed in. Happily, however, the farmer, who is very 

 intelligent, thought that there were signs of the disease
