others to follow in the same track. It may he as well to observe, that all 
the ordinary styles of grafting, inarching, or budding are performed for the 
sake of giving the scion a suitable stock to grow on, and the elongation of 
its own parts is just stronger or weaker in proportion to the suitableness of 
the stock on which it has to grow.

SILVER WHITE AND NONSUCH CELERY, 
the meeting of the Fruit Committee on the 20th of November I860, 
a large collection of Celery was exhibited. From this collection 
Veitch’s Silver White, and Ivery’s Nonsuch Red were selected as the 
two best sorts; and from the favourable way in which they were 
spoken of by the members I was induced to give them a trial in 
comparison with other popular varieties, all of which were subjected to the 
same routine of culture. I am very glad to he able to confirm practically 
the favourable opinion expressed, as these two sorts very materially sur¬ 
passed the others, not only in flavour and solidity, hut also in good-keeping 
qualities. I did not attempt to prove them for size, although I have no 
doubt they might he grown as large as any other variety, by the same 
process of gross feeding, hut I am old-fashioned enough to have hut little 
faith in the utility or economy of growing very large Celery. On the 
contrary I find that which is of a moderate size will he most useful in a 
gentleman’s family. Great size can only he attained at the expense of 
quality—more particularly of the keeping quality, which is very important. 
In practice I find that sound firm leafstalks in a small compass and well 
blanched, are very much preferable to large and coarse sticks, which before 
they come to table must often have more than two-thirds cut away as use¬ 
less. Therefore considering that it requires as much space to grow one 
hundred large plants, as would suffice to grow two hundred of a more 
moderate size, I think the palm on the score of economy and usefulness 
must fall to the latter.

AERIAL ROOTS UPON VINES. 
2jT)T is remarkable how many different opinions have been advanced 
from time to time as to the cause of Vines emitting air roots, and 
recently several correspondents of acknowledged ability have pub- 
lislied their views in the pages of this valuable periodical. One says 
it is occasioned by unripened wood; another that it is for w’ant of 
reciprocity between root and branches ; and another that it is entirely owing 
to a warm humid atmosphere. Now, as far as my own observations 
have gone, I unhesitatingly adhere to the latter view; hut the most
