Erasure or blotting out of written words. Obliteration is not limited to effacing the letters of a will or scratching them out or blotting them so completely that they cannot be read. A line drawn through the writing is obliteration, though it may leave it as legible as it was before. See Glass v. Scott, 14 Oolo. App. 377, 60 Pac. 186; Evans’ Appeal, 58 Pa. 244; Townshend v. Howard, 86 Me. 285, 29 Atl. 1077; State v. Knippa, 29 Tex. 29a
