Bulletin 68. 



Professor Craig, of Ottawa, writes of the species : "I have 

 been sending out cuttings of these so-called Russian poplars to 

 Manitoba and the Northwest Territories for the past four years. 



The species 

 which has given 

 best satisfaction 

 so far is onecalled 

 Populus Certi- 

 nensis. It resists 

 drouth and cold 

 remarkably well, 

 and is looked 

 upon by the 

 settlers of the 

 Northwest Ter- 

 ritories as one of 

 their most valu- 

 able shelter and 

 timber trees." 



The Certinen- 

 sis poplar was 

 used in the la- 

 goon plantations 



at the World's Fair, but because of its rapid growth in the direction 

 of its leader, it made a less picturesque small tree than either the 

 Cottonwood or balm of gilead, which were similarly planted.
