Having known these facts for several years, I was agreeably surprised to encounter a large group of hackberry trees (Figure 1) while I was fishing along the Mississippi River at Carleton Place. I have never heard this grove mentioned in conversation with field naturalists and I am convinced that this is the exact locality that Mr. Groh stated in his article (1942): "Ontario: south side of Mississippi River, near foot of rapids, Carleton Place, A. H. D. Ross, June 11, 1909 (Can)." The nearest com- parable grove is on Point Pelee, in southernmost Ontario, 500 miles to the southwest.
