THE TAMARACK SWAMP. 
This section lies between the lowland on the south and the marl bog' 
on the north and a few years ago was a typical tamarack swamp. The 
trees have been cut off, the land has been thoroughly tiled, like the 
rest of the wet sections of the valley, and is now a dry field. It is a 
nearly level stretch, slightly rising toward the east end where it merges 
Into the lowland. The vegetation is still characteristically that of 
the tamarack swamp.
