alba L. Very common on the sand-hills and in the 
bluffs on the prairies. It is a scrubby species, and seldom exceeds 
thirty feet in height, bnt yields very hard wood. I saw no other 
2 Stein vi the genus in Manitoba. 
erus virginiana L. Known as the “Ground Juniper.” 
A Sharactaristic and abundant species ee the sand-hills and on 
sandy portions of the prairie. Were it not for this plant, large 
areas of the sand would be perpetually shifting with the wind. The 
juniper covers the ground as with a dense carpet, which often 
extends over many square yards toge Siew. Its branches never rise 
more than two or three inches above the ground, but run along its 
surface, crossing and recrossing one another, and throwing out 
os branches, which prevent the sand from drifting. When 
eine ones are left upon the ground and look much like so many 
charred ropes. A useful list of the trees growing in Manitoba, by 
Dr. Robert Bell, will be found in the first (1882) ": Baport of the 
Department of Agriculture of the Province.’
