A very good way for an amateur in the country to give an 

 order to his nurseryman, is, to write for one sort of each 

 class, and that sort the cheapest ; sixteen plants, which may be 

 purchased for less than 4l., will thus give a very good repre- 

 sentation of the entire collection in the Chiswick garden. 



Mr. Smith offers nothing new on the cultivation of dahlias, 

 unless it be that they do not succeed well when placed more 

 than once in the same soil, " and that, if it is desirable to have 

 them always in one situation, it is necessary to renew the soil, 

 by trenching it deeply the second, and taking it out and 

 replacing it the third and succeeding years. It will seldom be 

 found advisable to add manure ; fresh soil is all that is 

 necessary." 



In a postscript it is observed that M. Poiteau, in the Bon 

 Jardinier for 1827, has described 115 sorts of dahlia, the 

 greater number of which, Mr. Smith thinks, " are perhaps 

 strangers in our gardens." Another proof of the endless vari- 

 ation of this flower. 



15. On the Cultivation of Camellias in an open Border. In a 

 Letter to the Secretary. By Mr. Joseph Harrison. 



A double red, double white, and double striped camellia 

 have stood two or three winters in a sheltered part of the 

 shrubbery at Wortley Hall. The soil is a brown loam, upon 

 a rocky substratum. We saw the plants in October, 1826, 

 and found them healthy bushes, between three and four feet 

 high ; and Mr. Harrison informed us that they flower freely 

 every year, from April to July. The white variety is the least 

 vigorous in its growth. When camellias are to be grown in 

 the open air, Mr. Harrison recommends the choice of strong 

 bushy plants, well supplied with roots ; to loosen the fibres 

 outside of the balls, and spread them out in direct lines from 

 the ball, so as they may push forward immediately into the 

 soil of the border ; and to place the balls so low that, when 

 the soil is levelled, the top of the ball may be four inches 

 below the surface. These directions we know from experience
