have passed from the tropics to our par- 

 terres, and even to those of higher 

 northern latitudes. The horse chesnut 

 is a native of the tropics, but it endures 

 uninjured the stern climate of Sweden.

 we all remember to have passed from our 

 stoves to the greenhouse, and now they 

 are in our open gardens. Every year 

 renders us acquainted with instances of 

 plants being acclimatized ; and in addi- 

 tion to those already noticed, we find 

 that Mr. Buchan, Lord Bagot's gardener, 

 at Blithfield House, in Staffordshire, has 

 an old cinnamon tree (Cinnamo'mum 

 Cassia] under his care which ripens seed : 

 from these many plants have been raised 

 that endure our winters in a conserva- 

 tory without any artificial heat. Then, 

 again, there is no doubt that all the 

 conifers of Mexico, which flourish there 

 at an elevation of more than 8000 feet 

 above the sea's level, will survive our 

 winters in the open air. Among these 

 are Pi'nusLlavediw, P. Teoco te, P. pa tula, 

 P. Hartwe'gii, Cupre'ssm thurifera, Jum- 

 per us Jla'ccida, and some others. We 

 have kept Phimba' go Larpe ntce in an open 

 border at "Winchester during the severe 

 winter of 1849-50, and it is now (Sept- 

 tember) covered with its blue flowers. 

 In this instance and the course should 

 be pursued in all other cases we selected 

 a light soil thoroughly well drained ; 

 and we began early to introduce the 

 plant to our climate by bedding it out in 

 May. As to all plants of shrubby or 

 tree character, there can be little doubt 

 that a proper solidification of the wood 

 by gardeners termed ripening is the 

 true basis of acclimatization. The way 

 to effect this is by encouraging a some- 

 what early and free growth, and an 

 early and decided rest. Light shallow 

 soils, thoroughly drained, necessarily ac- 

 complish this, by promoting -an earlier 

 root action, and by exposing the roots 

 more to the influences of the atmosphere, 

 whereby the very droughts of summer 

 become beneficial by checking luxuri- 

 ance, and bringing on the resting period 

 betimes. In annual plants it must be 

 confessed that scarcely so much progress 

 has been made as in those of a woody 

 character. It is not quite plain that our 

 kidney-beans, cucumbers, capsicums, to- 



matoes, &c., are any hardier than they 

 were a century ago. Such facts, how- 

 ever, should by no means deter those 

 who possess opportunities from trying 

 very new plant, as above suggested. 



A'CER. The Maple. (Acer, hard, or 

 sharp; because the wood was used for 

 Lances. Nat. ord., Maples [Aceraceaej. 

 Linn. Sys., ZZ-Polygamia 1-moncecta). 

 Nearly all hardy deciduous trees and 

 shrubs, with trivial flowers. Propa- 

 gated by seeds sown as soon as ripe ; 

 layers in autumn, and grafting, or 

 budding, on the common maple. Cut- 

 tings will strike in open ground, if in- 

 serted in spring or autumn. Sandy loam.
