If these figures may be considered as representative, it would appear that the 

 number of trees per acre along the base is 60 per cent greater than along the top of 

 the ridges ; i.e. the reproduction along the base of the ridges is more promismg. 

 There is practically no reproduction of coniferous species on this area except balsam. 

 This, however, together with cedar, is plentiful in the moister situations. The 

 stumps on the ridges disclose the fact that pine, now entirely absent, once occupied 

 them at the rate of 60 trees to the acre. 



In a thin strip next to the highway along the Hastings Road grants, however, 

 second growth white pine may be found in sufficient numbers to indicate future 

 commercial quantities. In the old bum to the eastward of Bass lake, one finds 

 patches of good reproduction in lots 17 and 18 in the 17th concession, where the 

 stand is of the following composition :

There were about 50 acres in this stand and, with the exception of a few small 

 patches, this stand contained the only white pine reproduction discovered in travel- 

 ling two miles through the old burn. 



Limerick and Cashel. — North of Salmon lake and Devil lake in Limerick and 

 Cashel, an old burn covers some 16,000 acres within the watershed and extends 

 beyond it on the eastern and western sides. The area has been burned at least three 

 times, 35, 20, and 10 years ago. A few patches of pine reproduction, however, 

 appear to date from a fire 75 years ago. These were probably too small to be cut 

 when the region was lumbered about 35 years ago, and escaped the subsequent 

 fires. In order to determine what might be expected after 75 years on an area burned 

 but once, sample plots were made in these stands with the following results.
