"Les jouets. Le Toton" (manuscript).
The primitive fountain, the "antique appliance" transmitted by inheritance, "the invention perhaps of some little unemployed herd-boy," consisted originally of three apertures and three straws; two similar apertures on one side, with two short straws, which dipped into the water, and a single orifice on the other side for the longer straw which delivered the water. Happening one day to use only two straws, one on each side, the little Fabre perceived that the device worked just as well, and "so, quite unconsciously, without thinking of it, I discovered the syphon, the true syphon of the physicist." Loco cit.
