lot at Edinburgh, it was rather prevalent in the field crops in Mid and 
East Lothian in 191 7. It is most injurious to the crop, and if it occurs 
badly again will demand investigation. Many of the varieties gave 
an average of 4 lb. a root, which at 3 feet X 18 inches represents a 
crop of 18 tons an acre. 
Professor Seton, discussing future trials, says : "It becomes a 
question as to the relative merits of a repetition of the same experi- 
ment or a test as you suggest between new varieties and the older 
varieties that have done best this year." Professor Seton favours a 
repetition of the 191 7 trial because " one season's results are not 
sufficient to determine which are the best." In these times of labour 
shortage and so many calls on one's time I feel loth to ask busy men 
to undertake extra work, but most, I think, will agree that we should 
do something in 191 8. 
The following table shows the total crop at each of the stations
