Jacob  walks up from behind a flat  ligne  of the dune, directly towards us. Looks like an ambush, shoot him down before he gets near (says someone in your pioneer party, the one who steals  eau  in the evenings).     Le lendemain matin me trouva à White Sands, les Sables Blancs, une vaste étendue de gypse pulvérisé, l'ingrédient principal du plâtre.
