In England, as we are informed in Sweet's excellent com- 

 pendium, the Botanical Cultivator, the Morina is generally 

 kept in the green-house, in any light rich soil, and is increased 

 by dividing at the root, or by seed. 



55. On the Steele Apple, or Codlin. By M. F. Wiederhold, of 



Hochster. 



The apple alluded to is our Carlisle Codlin, which is said 

 to be abundant in Westphalia, but not very common in 

 Prussia. It is recommended to be generally cultivated, as 

 being easily propagated by cuttings, as ripening in August, 

 as seldom tailing to bear a good crop even in bad seasons, as 

 applicable to various culinary uses, not bad for the dessert, 

 and as keeping six months. 



56. Observations on the Culture of the Double Georgina, Georgma 

 variabilis, our Dahlia sambucrfolia. By M. Fintelmann, Royal 

 Gardener in the Island of Peacocks at Potsdam. 



The dahlia received about the same time two different 

 names from two different botanists, unknown to each other. 

 Cavanilles, who discovered the plant, dedicated it to Andrew 

 Dahl, a Swedish botanist, author of a small volume of botani- 

 cal observations, while Willdenow named it in memory of Dr. 

 Georgi of Peters-burgh. The name of Cavanilles having been 

 first given, and also given by the discoverer, according to the 

 etiquette of naturalists claimed to be preferred, and dahlia has 

 accordingly become the general name, and is adopted in sub- 

 sequent parts of the Prussian Horticultural Transactions. 



M. Fintelmann has given a complete course of dahlia 

 culture ; but, as it differs little from that in general use in 

 this country, we shall merely glance at his divisions of the 

 subject. 



liaising from Seed. — A moderately warm dung-bed is formed 

 in the beginning of March, and the seed thinly sown in leaf 

 mould, in pots or boxes, and covered with the same soil, mixed 

 with river sand, to the depth of half an inch. If the seeds are 

 fresh, the plants will be fit to prick out early in April, and 

 they should be nursed in another bed till the beginning of 

 May, when they may be planted out in the open garden. 



Soil. — Any garden earth, but it must be well supplied with 

 moisture. M. Fintelmann uses one part of the natural sandy 

 soil from his garden, one part of soft clay, containing 10 per 

 cent, of marl, and one part of rotten wood earth from the 

 carpenter's yard. In this mixture both young and old plants 

 grow vigorously. Holes, in the situations where dahlias are
