CH. IX.] DEATH AND DECOMPOSITION. 317 



Doiiglasii have been found to sumve our \\-inters in 

 our garden borders ; the first in Scotland and Suf- 

 folk, and the second in Herefordshire ^. 



Another fact is, that many tropical plants of 

 every order and species have been found to re- 

 quire much less heat, both during the day and 

 during the night, than gardeners of a previous 

 century believed. Other plants than those already 

 noticed have passed from the tropics to our par- 

 terres, and even to those of higher noitheni lati- 

 tudes. The horse chestnut is a native of the tropics, 

 but it endui'es uninjured the stem climate of Sweden, 

 Auciiba Japonica, FcEonia Moutan, we all remember 

 to have, passed from our stoves to the green-house, 

 and now they are in our open gardens. 



Every year renders us acquainted with instances 



of plants being acclimatized ; and, in addition to 



those already noticed, we iind that Mr. Buchan, 



Lord Bagot's gardener, at Blithfield House, in 



Staffordshire, has an old cinnamon tree {Laurus 



Cinnamonum) under his care, which ripens seed: 



from these many plants have been raised that 



endure our winters in a consers'^atory without any 



artificial heat^. Then, again, there is no doubt that 



all the conifercB 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.
