192 Canadian Forestry Journal. 



Dr. Jas. Fletcher, the Entomologist, gives descriptions of 

 the principal forest insects observed to have been destructive 

 during the year. The Ash Leaved or Manitoba Maple appears 

 to have had the largest number of enemies. They include the 

 Basswood Looper, which destroys the leaves, the Negundo Twig- 

 borer, which the name sufficiently describes, and the xNTegundo 

 Plant Louse. In regard to the last. Dr. Fletcher states that 

 when not controlled by spraying with kerosene emulsion or 

 whale oil soap solution, these plant lice do serious injury to the 

 trees they infest ; and they are so persistent in their attacks that 

 many lovers of trees in the West have given up the cultivation 

 of the desirable and quick growing Negundo for other trees less 

 subject to insect attack. 



Summary Report of the Geological Survey for 1904; Dr. Robert 

 Bell, Director. Pp. 392. 



This report contains the accounts by the different officers 

 of the survey, of the explorations and surveys made through- 

 out the Dominion during the season. While they relate mainly 

 to the geological features of the country there are some notes 

 in regard to forests and timber that are of interest. 



The district at the headwaters of the Albany and Severn 

 Rivers, which will be near the line of the new transcontinental 

 railway, presents some interesting features in tree distribution. 

 Spruce, poplar, banksian pine and birch are found everywhere 

 over the whole district. White and red pine were noted only at 

 the southern part of Lac Seul. One solitar\^ white pine tree 

 occurs on Slate lake, and this appears to be the northern limit 

 of the tree in this district. Ash trees were observed here also 

 for the last time on the way north. The white cedar is a rare 

 tree; and this is its northern limit. 



Large areas have been burnt along the route of the Wenasaga 

 river, notably at Wenasaga lake, ten or twelve years ago, and at 

 Big Portage lake, about five years ago: also on Gull lake. North 

 of Cat lake, we enter, at the lower end of Cedar (Kishikas) lake, 

 an area that has been burnt probably eight or nine years ago, 

 and this extends to a few miles below the mouth of the Francis 

 river, or a distance of over thirty-five miles. Eastward it 

 extends at least to Windigo lake, ten or twelve miles to the right 

 of the river, and westward as far as could be seen from the tops 

 of the highest hills. This is generally being reforested with a 

 second growth of banksian pine and poplar. 



In very few places, either on the north or the south sides of 

 the height-of-land, do the spruce and tamarack attain such a 

 size as to make them economically important to the lumbering
