1908.] Swedish Red Clover. 607 



to be free from it. The Chilian variety was most affected, 

 about one-half of the plants disappearing, the other two beds 

 losing about one-third of the plants. Two other plots sown 

 with Swedish red clover in another garden, and respectively 

 -* treated " and " untreated " with affected soil, also appeared 

 free from disease. 



An inspection of the six beds on 9th September, 1908, showed 

 that the untreated Swedish bore the strongest crop, the 

 " treated " bed being about the same, but perhaps a little 

 weaker. The cow grass and the English red clover were about 

 equal, but the plants were not so numerous, the Lincolnshire 

 grown clover was poor and going off, while the Chilian variety 

 was weak. 



The Swedish clover was much later than the others at the 

 time of cutting and produced only a small after-growth. Up 

 to the middle of September it had not shown disease and 

 appeared to be lasting well. The diminished yield of the 

 second crop was due to the smallness of growth, and not to the 

 disappearance of the plants as in the case of the Chilian variety. 



The reports received from the other centres were less satis- 

 factory. Professor Seton of Leeds University states that the 

 sample was sown in May, 1907, in soil which had carried red 

 clover since 1901. During that period the clover had been 

 once renewed, and distinct damage by Sclerotinia was noted in 

 several years. The plot sown with Swedish seed showed no 

 striking features, but in September last it was very thin and 

 becoming impure owing to the growth of weeds. No trace of 

 disease had been observed, but it did not seem to have estab- 

 lished itself so well as the previous sowings with British seed. 



The manager of the experimental farm of the Department 

 of Agriculture, Cambridge University, Mr. H. Henshaw, reports 

 that the seed was sown at the farm and carefully watched, 

 but instead of having any special properties in the way of 

 resistance, it appeared to have none at all, for whereas a partial 

 crop was obtained from double- cut cow grass grown alongside 

 and under the same conditions, the Swedish clover did not 

 yield a single plant, all having died off during the spring. 

 The crop also failed at the Harper- Adams Agricultural College. 



The Swedish red clover sent for trial would appear to be a, 

 compact and hardy form of cow grass or " single-cut clover."
