424 Review of Loudon's Gardener^ Magazine. 



Gray's work in the hands of all persons, as an elementary text 

 book, who really wish to acquire a knowledge of the most useful 

 and interesting branch of human knowledge. For the future 

 gratification of such, we are happy also to be able to state that 

 the long expected work by that distinguished botanist. Professor 

 Torrey, viz. a " Flora of JS^orth ^merica,^^ arranged in the 

 natural method, is in course of rapid preparation, and the first 

 volume will probably be published in the coming spring. Its 

 completion will be looked for with an anxiety commensurate to 

 the arduousness of the undertaking, and the high and well known 

 abihties of the author for such a difficult and laborious work. — D.

 gator of plants and, also, an excellent landscape gardener, he 

 having laid out the public gardens at this place. 



Of the many amateur and private gardens which abound in 

 Frankfort, are mentioned those of the Baron Von Bethmann, 

 Baron Von Rothschild, M. J. Andreae, sen., &c. The garden 

 of the last named gentleman contains a fine collection of succu- 

 lent plants. Cereus senilis, said to be a splendid species, is cul- 

 tivated in the following simple manner: — 



" The old plant is cut in two (transversely we presume), and the head 

 planted, which produces a magnificent plant: the parent stem after- 

 wards puts out young shoots every year, which are cut off when they 

 are about the size of a large hazel-nut: and, after they have lain for 

 some weeks in a dry place, they are planted in sand, and kept in a damp 

 state till the young roots appear; when, by frequent watering, the plants 

 will continue to grow well. It is necessary, however, to observe, that 

 this operation should take place in a warm dry house, by which means
