The advantages to be derived from this method are numerous, and 

 must be evident even to the casual ol)server; the principal of these are 

 5 the regularity of the sup|)ly of moisture, 



without any chance of saturation; the pow- 

 er of examininj; the state of the cuttinjfs at 

 any time, without injuring them, by lifting 

 out the inner pot; the superior drainage, 

 so essential in propagating, by having 

 such a thin layer of soil; the roots being 

 |)laceil so near the sides of both pots; antl 

 the facility with which the plants, when 

 rooted, can be |)arted for potting off, by 

 taking out the inner pot, and with a com- 

 mon talile-knife, or the like, cutting out 

 every jdant with its ball, without the awk- 

 ward, but often necessary, process of turn- 

 ing the pot upside down to get out the 

 cuttings.

 potsherds, or broken crocks; c the sand or other soil in which the cut- 

 tings are inserted; and rf, the water in the inner pot." 



Art. 5, entitled "Notices of remarkable trees growing 

 near London," contains nothing of interest to our readers. 



The sixth article is a "list of trees, with their prices, in 

 the London nurseries, for planting an arboretum, on a 

 comprehensive scale, with the smallest number of plants, 

 &c. By the Conductor. Li the introductory remarks, he 

 states : 



"So many of the names in the nurseryiDen's catalogues stand as those 

 of species, while, in fact, they are only those of varieties, or are synono- 

 mous, that we think we shall be rendering a service to those who intend 

 planting arborelums this season, by giving a list of trees, which, accord- 

 ing to our o[)inion, will comprehend almost ail the species procurable in 

 the London Nurseries, and also some of the best and most distinct va- 

 rieties, 



" It must not be supposed, while we contend for limiting the species, 

 that we deny the distinctness of many of the varieties: as well might 

 we pretend to say that all the garden varieties of the apple and pear 

 were exactly the same thing as the crab, and should be neglected accor- 

 dingly. All that we wish is, that varieties should not be passed off as spe- 

 cies; partly to simplify the business of planting arboretums, and jjartly to 

 prevent gardeners and others from puzzling themselves to find specific 

 distinctions, when in reality, none exist. It is this rage for making species, 

 and parade of nice technical distinctions, which, with many, has turned 

 practical botany into ridicule. Acctording to our ideas of a s[)ecies, there 

 is none which may not be distinguished, as such, in the seed before it is 

 sown, and in the infancy and maturity of the plant, and at every season 

 of the year. We are aware that this will not be agreed to by many acute 

 botanists; but we shall hereafter, in the Arboretum Brilannicum, explain 

 ourselves at length, and trust to the common sense of our readers." 



The list is too long for insertion here, it containing about 

 800 plants. It includes eight species of Magnolm, fifteen 

 of maple (J.^cer), thirty-eight of Cratte^gus, and about twelve 

 of oalf (Quercus), and many evergreen trees and shrubs. 

 The cost of such, in England, of small size plants is about d£30 

 sterling ; but they would cost here double or treble that sum.
