tato with the eye of another. On July 14 I examined two sets 

 an eye of Royal Albert (a handsome, round, white potato) grafted 

 on Paterson's Scotch Blue. The eye had held perfectly fast to 

 the tuber, giving hope of some influence being exerted between 

 the stock and the graft. I made the graft fit as perfectly as pos- 

 sible into the wedged-shaped cavity in the tuber ; but at the above 

 date the graft had swelled out of its first position, though not suf- 

 ficiently so to disunite itself from the cicatrix of its own skin and 

 that of the stock on one side. I gave several good tugs at the 

 graft, but could not displace it ; and I sent it to Dr. Masters for 

 verification. Dr. Masters wrote, " in one case the cohesion was evi- 

 dent ; but I do not see that the new tuber or haulm is at all 

 affected. We must have more conclusive evidence. I see the 

 union is not merely along the rinds, but in the cellular mass of the 

 Potato as well. I have forwarded the tubers to Chiswick. The 

 whole subject is very interesting." 



The other sort sent to Dr. Masters was the eye of a Paterson's 

 Scotch Blue grafted on Royal Albert. No cicatrix or union of the 

 skins had been formed ; but some of the young tubers were half- 

 coloured, others less coloured, and one was perfectly white, none 

 of them showing blue all over like the grafted sort. I asked Dr. 

 Masters to forward them tojMr. Barron, and request him to plant 

 them and note whether the colouring was permanent. 



Noav " for more conclusive evidence." I wrote on July 14 

 that I durst not meddle with the roots of my last year's grafted 

 Potatos. Their appearance I noted thus : — Penn's Onwards on 

 Almond's Yorkshire Hero : an Onwards haulm, but earlier and 

 very diminutive in comparison. Hero on Onwards ; I can per- 

 ceive no difference in the haulm as compared with those not 

 grafted, except perhaps that the foliage of the grafted sets is of a 

 more glazed green. Yorkshire Hero on Pluke : haulm looking 

 like that of the true Yorkshire Hero, with not a symptom of that 

 dark-green tinge of the Pluke foliage. Milky "White on York- 

 shire Hero : haulm like that of a diminutive Milky White, quite 

 ripening off, whilst its namesake by its side was in full vigour of 

 leaf. Milky White on Pluke (this by mistake ; I intended to graft 

 the Milky White on itself, to try what would be the effect, if any) : 

 haulm showing quite a different character from that of Milky 

 White, not so branching, and of a darker, more upright, and ro- 

 bust habit. All the above examples in 18G8 uuited at the riuds 

 more or less completely soon after they were planted out, a fact 

 which I proved by inspection.
