Consider Her Ways by Frederick Philip Grove

[Containing our adventures with slave-making Rubicundas and Polyergus, and the marvellous speculations of Bissa-tee on the same; a report of the single combat between Assa-ree and an Amazon; the supreme disaster of the human road; further evidence of Assa- ree's treasonable practices; the crossing of the great river by means of metallic threads spun by great spiders; the trial and execution of Assa-ree; and my own speculations with regard to the final stage of degeneration perhaps not yet reached by any slave- making ants.]

It was a strange coincidence that in course of time we should once more have run across our old human enemy the Wheeler. But one day, a month or so later, there he was again, crossing our very line of march a few thousand antlengths ahead, riding on his two wheels. I promptly gave the signal to halt and to lie low.
