The article below was published in the daily newspaper Le Progrès, Lyon, France, on April 29, 1978.
A farmer from Lays-sur-le-Doubs, near Pierre-de-Bresse, Mr. Ernest Joly, aged 52, discovered in the middle of a plot sown with barley, with an area of one hectare and whose shoots reached six centimeters in height, a furrow 8.60 meters long and two meters wide, with a depth reaching 40 centimeters in the center! Each end of the furrow ends in a point. Within a perimeter of 10 meters around this cavity, several cylindrical anchor points, six to eight centimeters in diameter and 12 to 14 centimeters deep have been identified.
On the walls of the furrow and the extraordinarily polished anchor points appears a gray substance. Samples were taken by the gendarmerie.
There were no signs of footsteps or burns near these mysterious tracks. This happened 400 meters from the nearest thoroughfare and a great distance from any dwelling, between Pierre-de-Bresse and Lays-sur-le-Doubs.
