PLANTING OF SIBERIAN LARCH IN CANADA, LARIX SIBIRICA. 
At Indian Head, Alberta, where the temperature goes to at least 50 degrees below zero, 
Mr. N. M. Ross, Superintendent of the Forestry Station of the Dominion Government, has a planta- 
tion of this rapidly growing Siberian larch, which is now 8 years old. Its rapid growth and 
hardiness made it seem to be an unusually promising tree for the forest belts of the plains region of 
Canada, but unfortunately a bud moth has become established in the plantation and has interfered 
with its progress. In regions in this country free from this pest it deserves to be further experi- 
mented with. In Plant Immigrants No. 72 is shown a photograph of a large tree of this species in 
Siberia. Photograph, courtesy of Mr. N. M. Ross.
