which we planted out in December, 1869 (see Sy 
above) have grown very well, and now look very 
healthy and handsome, but the two in the 
pleasure ground have not yet grown high enough 
to be beyond the shelter of the shrubbery.

Lambert, Pin. v. 1. 24. table 26 and 27. 
Loudon, v. 4, 2252. 
This tree will not bear the winters at Barton. Pinus

We have some plants raised from seed, which are 
treated like Rhododendron arboreum ; plunged 
during summer, and kept in a cool house during 
winter. Thus treated, the foliage looks healthy 
but the stem grows very slowly, assuming the 
character of a dwarfed old tree, like I’inus halepensis 
and others when growing on very barren rocks.

‘level in the Himalaya and ‘‘is a common tree 
“throughout the whole region” (the temperate 
region of those mountains) ‘‘from the mountains of 
“the Punjaub to the East of Bootan. It is confined

‘“mountains, and commences as low as one thou- 
‘‘sand feet above the level of the sea, rarely, if ever
