IN THE JURA
A FLYING SAUCER!
PORRENTRUY, 24 (C.P.) -- Mr. and Mrs. Périat, mechanic in our city, state to have seen in the night of Monday, a flying disc resembling a "lumineux sun" [like those] used at the 1st of August, placed horizontally. The witnesses, worthy of faith, say that the saucer flew at the speed of a jet airplane and disappeared towards the south-west after having flown over Porentruy.
