disease is at work, and plays a prominent part in the spread of 

 some of the most dreaded of fungus diseases. 



The above discoveries, indicating hitherto unsuspected 

 methods of perpetuating and diffusing fungus diseases, may 

 at first sight appear to the practical man, who naturally desires 

 a cure for every ill, as anything but reassuring. This, however, 

 is not the case ; before any certain method of prevention can 

 be formulated, Vv'e must be in possession of all the facts that 

 render such prevention necessary. At all events these dis- 

 coveries have clearly indicated the futility of treating barley 

 seed for the prevention of smut, when it is known that 

 infection takes place in the flower, and have shown the great 

 risk incurred in using seed, tubers, bulbs, &c., produced in an 

 infected area, in the case of those plants known to be capable 

 of perpetuating a disease by means of hybernating mycelium. 



TRIFOLIUM INCARNATUM. 



Italian or Crimson Clover. 



In the economy of the farm the members of the family 

 LeguminoscB — and in particular the genus Trifolium — offer to 

 the farmer a somewhat wide range of valuable fodder crops, 

 varying perhaps in their feeding value, but well suited by their 

 diverse characteristics for different purposes and soils. Among 

 seed-merchants both at Mark Lane and in country markets 

 and also among the farming community, the generic name 

 "Trifolium" is, however, commonly applied to the species 

 Trifolium incarnatum or Crimson Clover. 



Crimson Clover is a native of the South of Europe, and was 

 introduced as a field crop into this country some time about 

 the second decade of last century. It was about that time 

 that Sir John Sinclair encouraged, or at least interested himself 

 in, its culture in Scotland. Afterwards it was grown in many 

 parts of England with more or less success. Previous to its 

 introduction as a field crop, and doubtless owing to the size 

 and beauty of the flower head, horticultural writers and gar-
