Horses at plow so teized by flies as to be quite frantic. Horses are never tormenteed in that manner ’til after midsumr: the people say it is the nose-fly that distracts them so. I can discover only such flies as haunt the heads of horses: perhaps at this season they lay their eggs in the nose & ears. I never can discern any oestrus on those days, only swarms of small muscae.
