In the present year a good many other stations will probably be added. With a 

 car at their disposal the points could be readily reached and often much time saved. 



The investigation might also be extended beyond the province of Ontario. The 

 St. John river, N.B., has a large area that may possibly be suitable for mussel cul- 

 ture. Ten miles above Fredericton the Keswick stream enters from the north, and 

 below this point the bed is literally choked with alluvial islands. At Sugar island, 

 tlie largest of the group, the river measures 2-5 miles from bank to bank. From 

 Fredericton to Gagetown, a distance of 34 miles, the surrounding land is very low. 

 On the east a mere alluvial flat of great extent separates the waters of the St. John 

 from those of the Jemseg. Some farmers here obtain annually a crop of fish and 

 vgetables.^ A few of the upper sinuses that branch o£F to the east from the river 

 might also be suitable for clams. One would not expect to find our larger species 

 there now, but it does not necessarily follow that they would not thrive if introduced. 

 The greatest difficulty would probably be found in procuring the proper species of 

 fish to act as hosts. Here it may be mentioned that in the flood areas of the Missis- 

 sippi many fish, cut off from the river when the flood subsides, are caught, infected 

 and liberated again. In this way the double purpose of restocking " the river with 

 clams and reclaiming the fish is served. 



In Manitoba there seems to have been an immigration from the upper waters of 

 the Mississippi region. I am informed that in the Journal of Conch ology (Leeds, 

 Eng.) IV., pp. 339-346, 1885, there is an interesting account of the Mollusca of Mani- 

 toba by R. M. Christy. In a letter received from Dr. Bryant Walker, Detroit, Mich., 

 relative to this article, it is stated that the author (Mr. Christy) lists nineteen species 

 of which six are unidentified. They are: L. recta, radiata, luteola, horealis, and alata. 

 Q. ruhiginosa, plicata, lachrymosa, (and asperima) , undulata and heros. Symp. com- 

 planata; Siroph. edentula. Mussels in that region were abundant and especially in the 

 Shell river, which runs into the Assiniboine from the east, abcut fifty miles above its 

 junction with the Qu'Appelle. Hundreds of dead shells beloi. 'ing to many si)ecie3 

 occurred.
