Dans le miel ou le lait bleu de l’agate, les dendrites esquissent souvent des paysages: collines, vallons ou combes, toujours plantés de sapins que la distance rend minuscules et qu’on reconnaît à leur silhouette pointue et aux branches basses un peu relevées.

[Within the agate’s honey or blue milk, dendrites often depict landscapes: hills, valleys or ravines, sown always with fir trees which are rendered minuscule in the distance and which one recognises by their pointed outlines and their slightly elevated lower branches.]
