44 RELATION OF THE DISEASE 



in its own way ; some varieties will be more diseased than 

 others, and some will die down earlier than others. 



(170.) Some potatoes require more leaf than others, and 

 I have no doubt that those which require an extensive crop 

 of leaves are more prone to be influenced by the disease 

 than others. 



(171.) There is one kind of potatoe which has been 

 lately raised, which is called by the gardener a " go-be- 

 fore," which arrives at maturity earlier in the open bor- 

 der than any kind before known, and which has a top only 

 eight or nine inches high. The haulm is said to be ripe 

 by June, and thus does not exhibit the disease. 



(172.) At the Horticultural Society's potatoe-ground, 

 many kinds were found to have the tubers quite healthy, 

 while others were much diseased. The white-eyed red 

 was of the former class ; the Sourris Jaune of the latter. 

 I dare say that it will be found that the more nearly the 

 tuber reverts back to Gerard's old type, the more capable 

 it will be of resisting the disease. The white-eyed red 

 was in some respects similar to the old species in the 

 Chelsea Garden. 



(173.) I applied at the Horticultural Society's Gardens 

 for a return of the relative number of good potatoes to bad 

 ones in each sort cultivated by them, but was unable to 

 obtain it, as a similar return was ordered to be printed in 

 their own Transactions. 



(174.) However, after I had examined their potatoe* 

 ground, I found that I incurred no great loss by being 

 debarred from obtaining the above-mentioned return, for I 

 found that the disease had visited them with a compara- 

 tively lenient hand this year, and that it did not exhibit 

 itself in its most destructive form.
