cropper, but the quality is disappointing. It would probably 

 reach a passable standard on some farms, and fall short of this 

 on many others. 



The varieties in the group classed good are at least equal to 

 Up-to-Date in quality, and some of them surpass it. Quality 

 in potatoes, of course, will vary considerably with soil and 

 cultivation. On some farms the varieties classed here as good 

 would be very good indeed, while on others they would be no 

 more than tolerable. Their defect is a slight tendency to soft- 

 ness in the heart. The three heaviest cropping varieties fall 

 into this group. 



All the varieties styled very good were very satisfactory as 

 regards quality ; but when broken they fall short of the firm, 

 flaky texture which is characteristic of the Langworthy, and 

 which, along with fine flavour, entitles this variety to be ranked 

 as excellent. 



Comparing these results with those obtained at Leeds,* it may 

 be noted that the order of merit in which some of these varieties 

 were arranged in two tests in 1904 and 1903 was British Queen, 

 Empress Queen, Up-to-Date, King Edward VII., Royal Kidney, 

 Goodfellow, and Evcrgood. 



Some account of the experiments carried out in France with 

 a species of tuber of the potato family has already been given in 

 this Journal (Vol. XI., p. 412, Oct., 1904). 

 A New Tuber. This tuber, originally obtained from Uru- 

 {Solamon Com iner- guay, was cultivated experimentally by M- 

 so7ii.) Labergeiie, and produced in 1901 several 



distinct varieties, one of which, the violet 

 type, attracted much attention, and gave promise of proving 

 a useful edible variety, yielding heavily and being entirel}^ 

 resistant to disease. The cultivation of the different varieties 

 has been continued under very careful supervision, and it may 

 be noted that the varieties, as well as the orignal type, appear
