The remaining varieties were sown later, and were kept back owing to a 

 fall in market prices. As a result of the dry weather they finished badly, 

 and are not reported on here. 



It is exceedingly difficult to lay down anything very definite 



as the result of one year's trials. It is hoped that these trials 



will be continued on a commercial scale over a number of 



years. As a result of the first season's trials many problems 



have arisen. In addition to the main commercial results, such 



as yields and eariiness, there are other points which require 



investigation, such as those mentioned in the paragraph on 



eariiness.

Mycologist, Pathological Laboratory , Ministry of Agriculture, 



Harjpenden. 



The discovery in England of the disease known as Pink Eot 

 adds another name to the already lengthy list of fungus diseases 

 which attack potatoes in this country. Pink Rot was until 

 recently known only in Ireland where, by destroying the tubers,
