July 58/
Droves of New Forest Ponies are driven for sale over the southern part of England, & on them handful of the Forest Fly can be scraped off, & yet these flies, though thus imported & with horses all round them, do not spread. In some districts, as in Ash-down Forest in Sussex, are they occurring every few years, & few are seen, whether or not due to the importation of N.F. ponies, & on what utterly unknown causes must this increase be due.—
