A typical pirogue trail through the marsh used by trappers in making their trap rounds. 



muskrat grasses have three sides, and the common designa- 

 tion of the marshes, "three-cornered grasses," comes nearer 

 being a correct term. 



Planting 



To replant an area with the known and proved muskrat 

 food grasses would call for a great amount of labor if the 

 replanting were done by transplanting and it is doubtful if 

 it would prove an economical plan. 



It would appear that such planting could be best done 

 by sowing seeds of the three-cornered grasses and cattail. 

 To find out the germination periods our field biologist was 

 directed to make the proper experiment. Seeds of the leafy 

 three-cornered grass (Scirpus robustus) and the broad and 

 narrow leaved cattail (Typha angustafolia and T. latifolia) 

 were placed in germinating bottles set in a sunny window.
