Hazon Ish - Two letters in Halacha in his handwriting

Two handwritten letters on the halachahs of shemittah from the author of Chazon Ish.

* Letter in which the Chazon Ish responds as to whether it is permitted to trim weeds so as to distance snakes from gathering there during the shemittah year, he determines that is is permitted under two conditions: that the trees don't need the weeds, and that the location is not meant to be sown: 'Weeding because of snakes in places where trees don't need those weeds, such as when the place is far from trees and all the weeding is just so that snakes don't gather, is permissible, and when that place is not meant to be sown.' After that, the Chazon Ish refers to chemical fertilization, which he had permitted during the shemittah year, he qualifies his words - that if without the fertilization the plant would not be completely lost, he is not deciding whether to forbid or permit: 'The chemical fertilization I permitted - my heart hesitates - perhaps even without fertilization, no plant would be lost, just that their development would be weak and thin this way. I'm not saying that it is forbidden, nor that it is permitted, it is difficult to decide. And when it is uncertain whether some of the plants would be lost, it is permitted.

* Letter in which the Chazon Ish responds regarding grafting a tree and the ban of hybrids (issur kilayim). Slightly damaged with damage to text at the beginning of the top line.
