tageous it is to grow wormwood for making potash ; the more 

 especially as it grows fast, and on any soil. 



54. Account of a Blach Carnation. 

 Extract from a letter of the Society for Fruit-culture, at 

 Gruben. " M. Ulrici raised a perfectly black carnation 

 from seed, which he called the Mohren Konig (Negro King). 

 He had a very large collection of carnations ; but, since it 

 has been dispersed, this black variety has been apparently 

 lost. The Society wishes therefore to know if it does not exist 

 somewhere, as M. Ulrici was very liberal in distributing 

 whatever rare varieties he possessed." 



58. On an Insect {Tenthredo erythrocephala) luhich is very injurious 

 to the Species of the Genus Finus, and particularly to Finus 

 Strbbus ; toith a Figure of the Insect. 



59. M. Bosse succeeded in preserving a bulb of Amaryllis 

 revoluta, which was much rotted, by cutting off the wasted 

 part, without injuring the roots ; on the wound he put pow- 

 dered charcoal, and kept the plant in a dry stove, until the 

 injured parts became dry, when he covered it with wax, 

 leaving an opening in the centre for the leaves to grow 

 through. After being repotted it was put in a warm frame, 

 where it soon began to grow, and attained its former size. 



60. On the Impregnation of the Species of Passion- Flo'vuer. 

 By M. Bosse. 



He approves of impregnating with the pollen of different 

 species or varieties ; in this case they produce fruit more 

 freely than when impregnated with their own pollen ; he has 

 also, by this cross impregnation, originated several varieties. 



61. Observations on the Character of the Regular and Natural 

 Styles of laying out Gardens, and their Application. By M. Sckell, 

 Inspector of the Royal Gardens in Bavaria. 



The different styles in which gardens are laid out may be 

 distinguished by the two appellations, the regular and the 

 natural. The first, and oldest, is also called the French 

 style, from its having been so much in use in that country, 

 and also for the great perfection to which it was brought 

 during the time of Louis XIV. and the great genius Le 

 Notre, wherefore all gardens laid out similar to those of 

 Versailles, St. Cloud, Marly, St. Germain, Meudon, Sceaux, 

 Chantilly, the Tuilleries, and the Luxembourg, are called 

 French. 



Another kind of regular style, a subdivision of the former, 

 is the Italian garden, which, although regular, differs greatly
