The other species of flies, we called Pontiacers. This is a Michiganname, and originated I was told, from one being caught near Pontiac witha paper tied or attached to it having the word Pontiac written upon it.

These flies were not fairly numerous; occasionally there were three or fouraround at once. When they were coming we could hear and look at them for somerods. Their fashion was to circle around the oxen before lighting onthem. I frequently slapped them to kill them, occasionally I caught them, inthat case they were apt to lose their heads, proboscis and all. Theseflies were fairly large, some were black and some of the largest werewhitish on the front of the back. I have seen some of them nearly aslarge as youthful humming birds. The Germans tell me they have this kind offly in Germany. But with the mosquitoes, these flies have nearlydisappeablack.
